Can confirm - Filled up at Morrisons Saturday, car is now in pieces on the drive.

All pump fuel sold in UK has to pass EU specifications!!! So supermarket fuel will not destroy your car at all. 'Premium' fuels may exceed EU specs and have better detergents or better anti knock properties but you are paying for them.
just think back when Shell introduced 'Formula Shell' that was unleaded petrol but there was no British Standard for unleaded! Shell didn't tell people it was unleaded with a lead substitute. They also charged regular or higher prices for the 'Formula Shell' and due to UK tax laws they paid less duty and thus more profit on the petrol! Subsequently it was proved that 'Formula Shell' was destroying engines (lots of Rovers if I remember).
Hence why pump fuel now sold in the UK has to pass EU test.

Sorry for long post, I used to test fuel and lubricants and it always bugs me when people say XXX brand of fuel destroys or damages engines.

Best advice is vary where you buy your fuel from. If you can feel the effect of premium fuel, can afford it, your vehicle specifies it, or think you will be keeping the car for many years then the extra cost may well be worth it.

Should've gone to spellchecksavers

Yes I will, thanks.

OK, so you are now becoming rather boring and tiresome.

The link you posted quite clearly states that the petrol was contaminated with silicon at the refinery/storage stage. This has nothing to do with the quality of the fuel itself, contamination of goods happens in all industries (horsemeat lasagne anyone?).

Admittedly if I could afford to drive (never mind own) a 'supercar' I would probably put 'Superfuel' in it. By 'supercar'; I mean Aston Martin, Bentley etc. or very top-end German/Italian. I cant afford one, so I dont and it doesn't matter. IF I could afford one I wouldnt give a toss about fuel costs anyway, and I dont think I would worry too much about adapting my driving style to make sure I get the best MPG either.
I drive an ordinary 7 year old average family car that doesnt give a flying **** what I put in it, or how much it costs. It just works - and it does about 45-50 to the gallon and thats all i want it to do.

Filled up this morning at this price!

Thanks for this, I'm touring in uk this month so this will save me a good few quid.

I don't know why but I find Asda tesco fuel doest last asking as other the established brand's own stations

OOooo thats so nice of them,what a lovely gesture,they must love their customers to do this ?

Or is it because the price of oil has dropped from $51 a barrel to c. $44 barrels right now. A 10% drop and they only knock off a penny or two.

Finally going in the right direction again

Marketing con. You`d save more instore by buying a buy one get one free box of cornflakes.

​It obvious that sky is on a tablet or phone, it's because of Android /spellchecker that the sentence came out like it did.

On the subject of fuel quality all the supermarkets buy their fuel on the "spot market" so the quality of fuel will vary (but not by much). Motion lotion pricing is still a bit of a rip off although the government is mostly responsible as it taxes by the litre not by the cost of the raw material.

Typical. Always in time for the english holiday. :disappointed:

Heat added anyway

False economy - you'd better off filling with a superior quality fuel given that Asda fuel is a much lower grade. Shell V-Power Nitro Plus, for example, has higher octane, so it gives more torque at low revs and more power at high revs. If you use the greater torque at low revs to upshift earlier then you can enjoy upto a 10 per cent improvement in economy. That pays the extra cost of the fuel. The other benefits of a clearer fuel system (valves and injectors) comes free of charge.

I did notice that prices had started dropping very recently.

High Octane Shell costs around 115.9p where I am... The amount my GTI drinks, I assure you it'd cost a hell of a lot more to use the premium fuels :wink:

Supermarkets fuel will destroy your car. You'd rather go to shell. Pay a small amount more for a higher quality fuel which will give you a few more miles to the gallon but won't mess up you car either.

​aslng as u gt wht I waaz syingh :smiley:

​yep on a android phone

Why not just post the Shell promotional leaflet that told you all this ********?

Meanwhile here in the real world, if fuel is 10p a litre cheaper right now at ASDA than it is at Shell stations then I, along with most other people, will make my savings right now (average car about £5 - £8 a tank) over some hypothetical, unproven in the real world, unspecified savings that Shell claim I might make in the future (as long as I adapt my driving style to accomodate Shells' 'super-fuel').

does redex work like premium quality fuel or is it something else

typical been on holiday and back then it comes down

No - I've personally tested this and not only notice the performance difference, but when coupled with Shell vouchers and using a cashback card, then it works out cheaper: I get 9% better mpg for 7% extra cost.

Supermarket fuels are cheaper for a reason: lower grade fuel.

Same price in my local Morrisons last Saturday when I filled up

What's your mpg?

What he said /||\

I'll stick with my local jet garage who match the prices of the local supermarkets.

Ignorance is bliss - Don't remember this then?

Sure supermarket fuels have to pass "EU specs" but it's a lower grade fuel, resulting in poorer lubricity and poorer economy.

You conveniently ignore key points: Firstly, premium fuels like V-Power keeps the engine fuel system clear of hydrocarbon deposits that can cause damage costing thousands as noted previously by somebody else. Secondly, it gives more torque at low rpm and if you use that to shift up earlier then you will be using less revs for the same performance and will enjoy an improvement in fuel economy as I've mentioned and benefited from for years. Thirdly, all modern engines are certified for mpg and CO2 in the ECDC lab tests on the best fuel available (to give them the best chance). Fourthly, you also get more top end power, typically 10% more, and if you want to use that rather than the increased torque you can enjoy better performance but, of course, by using more revs you won't get better fuel economy.

But hey, keep using cheap fuels if you wish to.

always wondered how the price to customers can fluctuate daily even though the delivery of fuel is weekly or longer! :stuck_out_tongue:

Cheaper if you got a Costco near you I payed 103.9 on Saturday

Why bother using if its already contained on some premium fuels?

Don't you need a Costco card?

Yes I will, thanks.

That's not exactly answering the question, is it? Plus for the price of a bottle, often £2 in my local supermarket, it offsets the cost of filling up with premium fuels/

Well I use a mix of 3 tanks or normal (usually Asda as a) Its closest and the only one with 24h pay at pump. b) cheapest) to 1 premium (Either Shell or BP but on occasions Tesco99).

This gives me a mix of good price and some extra cleaning (probably). While the engine defiantly sounds happier and probably produces a little more (unnoticeable) power I find I get less miles per gallon (guessing engine is running a richer mixture). As I claim expenses from work I pay lots of attention to mileage and fuel usage.

I also use redex for two tanks of fuel before service times (twice a year) of which one is before its MOT.

This routine has served me well for many years and will continue.

Because I'm right? Diddums...


Well it was found in supermarket forecourts wasn't it. People don't fill their cars in refineries do they?


It's not only about fuel economy. Also about performance. Do F1 cars use Asda fuels?


But you could get more at no extra cost, that's my point.

Wrong given you can often get superior economy as a percentage for the marginal cost. But don't let that stop you...

I won't, but thanks for your concern. I drive around in the wife's American, petrol drinking POS. So an extra 5mpg is neither here nor there for me.

It might not be, but more torque for "free" would be, no?

Being honest here, I have no idea what you mean. I literally drive my son to and from school, with the occasional dropping my wife to work etc. I don't drive anywhere else, as I work from home - I don't commute, or do lengthy journeys.

Good thing you don't drive a diesel then... :confused:

I'm actually eyeing up a diesel Smart Car, purely because of the minimal distances I drive. I don't know if my wife (she's disabled) will be able to get in and out of the thing though.

I literally work from a laptop, with my daft Basset hound as a company mascot/logo. Drives me mad; but without here, I'd not have a company name or focal point:)

What a load of crap bla bla Supermarket fuel will destory your engine. Supermarket fuel won't destory your car at all.. If you buy Standard Shell fuel it's exactly the same as the supermarket apart from a few additives to help clean the engine out of carbon build up. If you start looking into buying VPower that kind of fuel your looking at a higher octain level than your standard fuel and again contains addatives. No point putting Vpower in your car unless it's designed to run off 99 Octain (Will say on the inside of your fuel cap) as in most cases standard cars ECU's can't adapt to the fuel making it run exactly the same as supermarket fuel...

Factually incorrect. All modern engines are certified for mpg and CO2 in the ECDC lab tests on the best fuel available, i.e. RON 99.

That makes no sense

Why? Small engine, designed for short distance drives and hugely economical. Where's the lack of sense?

Because you'll be likely to end up with DPF or EGR problems. You don't need a diesel for that type of driving...

Check out the Golf GTE, got one in our household. Awesome for blitzing around town on electric, but with the ability to switch over to hybrid power for longer journeys. Making good savings on fuel so far when it comes to popping out into town etc, where stop start traffic hammers economy.

How much extra did the hybrid cost you?

i would advise to stay clear of supermarkets fuel if you want to save money in the long run.

Filled up this morning :smiley:
Heat added

I think that'd be above and beyond my budget, tbh bud. Also, with it being electric - I'd have to charge the thing? I have no way of being able to plug the thing into the mains. No drive way or parking in the garden:(

@m5rcc - I've not looked into any issues with the diesel variations yet. Like I said, they were designed purely for urban, short distance driving. So I imagine that if there were problems, they'd have been ironed out in the following generations of the car?

Its an inherent problem with all modern diesel cars. You would be better suited to a small petrol car.

I'll look into it. But bear in mind, the missus will probably drive the thing too (providing she can get in and out of it), so it'll be thrashed on the motorway at least three or four times a month...my wife's got a bit of a lead foot.

No because sadly there EU rules in the amount of CO2 and NOx that can be spewed out by cars and in order for those levels to be reached, filters such as the DPF have to be installed, as of a decade ago. The problem you will be likely to have is getting choked with soot from repeated short runs from cold and the effect that can have on the DPF active regeneration that can pump so much fuel into the engine that it blows itself up.

Then get the petrol equivalent. If she needs ease of access, maybe a Mazda 5 or a Ford C-Max. They are all 'walk-in' cars, best with flat unbolstered front seats...

Well that will certainly help. But I'm guessing the main pull is saving money. Sadly the MPG figures (especially in winter) over the first 3 miles or so are pretty dismal. So in real world money in the tank you will probably see little difference, while you will have paid more for the car and likely slightly higher service costs and higher ongoing costs (Tyres, brakes as car is heavier) you have not saved any money forgoing the potential DPF issues.

But in the end cars are a big lottery. I had French and Italian cars that have been great, but German and Japanese that have had many problems.

Not a deal.

I passed my test quite late in life. I drove around in the wife's Scenic for years, incredibly reliable thing. I'm in the process of considering so many different cars, from Aygo to Mini to Smart. Budget's limited - the joy of being self employed:)

not bad price op heat added but i usually get mine from applegreen in roi as it works out 98p.but for ni and ukthis is the cheapest you are going to find i think.

Out of the three the mini will be the most refined. The Aygo is likely to be the cheapest to own (fuel costs, service, parts and insurance). They are pretty much bulletproof too. The main issues are clutch issues on pre 2009 cars (upgraded to bigger 190mm ones on later cars, so make sure older car has had upgrade) and water ingress from door seals and also from the third brake light. To lesser extent some old high mileage cars will use a little oil due to old valve stem seals (inherent of many Toyota engines) but its not economically viable to replace them. Obviously look at the Peugeot 107 and Citroen C1 too as they are the same car.

Asda's is the cheapest for petrol and diesel.

Good to see prices still coming down despite the incredibly weak pound.

My local Asda was 108.7 for both fuels on Thursday so this is a decent price cut.

Well the funny thing is petrol is cheaper now than 6 weeks ago yet the pound has lost 12% of its value (Based on Brent crude trading price). So in reality its not making a difference and never does. The reason why Asda have dropped the price is Saudi Aramco announced their figures yesterday that demand had slowed and the inventory was high.

But in general the best things to do are, walk a bit more, drive a bit slower and look further ahead down the road. :smiley:

Awesome! Better get meself down to Costco

Captain Obvious over here!

If you're going to blame anyone, blame the government for the enormous duty placed on fuel.

As you're so superior let's look at the statement I was replying to i.e.

"i would advise to stay clear of supermarkets fuel if you want to save money in the long run."

The statement says that I will save money in the long run if I stay clear of supermarket fuels but doesn't say why.

If it was purely down to getting more mpg by buying non-supermarket fuel then it would not exclusively save money in the long run but would save money all the time.... therefore implying there is some other reason.

If it is down to fuel efficiency I don't believe supermarket fuels are less efficient than non-supermarket fuels for the normal octane stuff. I have looked independent tests in the past and there is little to no difference.

There may be an increase in mpg with the higher octane stuff with additives but it costs more - and there is no mention of this in the statement I am replying to... it simply says supermarket fuel costs more in the long run.

I tend to find I get a much better mpg in my Land Rover from Shell compared to Supermarket fuels but in my Nissan Micra it makes very little difference.

Each to their own however.

If you're driving around it's worth looking at http://www.petrolprices.com to check whose selling petrol or diesel at the best price.

If supermarket fuel is so rubbish why do you never hear about anyone having problems with it?

I do 20,000 miles per year (petrol) and always fill up at tesco or asda, not because it's cheap but it's convenient. Used to fill up on esso every week but got fed up of going out my way to get it. Mpg seems to vary more on amount of traffic and speed for me rather than what fuel I put in.

I passed within a 100 Yards of an ASDA Petrol Station today and my car, and the four behind it, spontaneously combusted. This Fuel is EVIL and must be destroyed; burn it I say!!!!!

my local BP station is always 112.9 in the week but only on Saturdays they put it to 108.9! which is the same as tesco's prices. only time I fill up is then ! its a steal I think for bp price on a Saturday !.

Oh dear - they saw you coming and welcomed you in, didn't they!

If you have one of the (few) vehicles on the road which needs premium fuel then use it (sorry, your seven year old Golf doesn't count). For the vast majority it's simply wasting money.

Just read the last lease deal you posted - don't think I'll take any motoring advice from you, thanks!

again deals with petroil..... when it was 97.0p ..it was deal but not now...also ....oil goes down... 2 weeks ago was 51 dolar..now 41....so expect same 1 pound price soooon
cold!

Cold only shell v power for me, supermarket fuel is watered down scum fuel

Cold only shell v power for me, supermarket fuel is watered down bad quality stuff

You're kidding right? This guy is a hotshot baller!

He already made like £1 million pounds in betting this year probably (or so he would like to have random people on the internet believe). I reckon all of his Ferraris need premium fuel.

No, it doesn't. Scots' summer holidays started weeks ago. They're nearly finished, in fact. Thanks, Asda, but next time take regional variations into account. You know, like you doe from branch to branch the rest of the time.

Oo Get you :laughing:

I may have missed it but does anybody know if asda fuel is better than shell fuel or not i cant decide

Typically Diesel engines don't enjoy short journeys. Wouldn't you be better off with a small sub 1 litre petrol? The extra cost of the car will surely negate any savings you make. Have a look at the Hyundai i10. Fantastic little car.

For premium diesel, it has 2 Ethyl Hexyl Nitrate (a cetane enhancer) added in addition to something not too far off injector cleaner (a detergent).

While the cetane enhancer will improve the burn of the fuel meaning less pollution, the additive cost is well under £1 per tank. The detergent, while being beneficial, is not needed constantly. So if you can't be bothered putting in your own additives, filling one in three times with premium fuel should keep the engines parts equally clean.

Its also worth keeping track of your fuel consumption, as some people claim they get far better MPG. But you don't know unless you risk that extra £8 to try!

After seeing all the comments i can't decide if this deal is for Shell or Asda fuel lol
i can't believe supermarket fuel destroys cars, locally to me the only options are Tesco and Morrisons petrol with out going miles out of my way for Esso if supermarket fuel did destroys cars nobody in my town would bother owing one

Its funny how they announce the price decreases but silently put them back up not long after

It was £1 not so long ago and then they put it up to 108- more in some places, was 122on the m5 the other day- why do we stand for these ludicrous price increases in this country ?

I've done tests on different fuels in my car (12 year old 2l Diesel) Shell fuel gave me no extra MPG (compared to Sainsburys where I normally fill up) at all. I record how many miles I do and always brim the tank till the pump cuts off so I know exactly how much I have used. Then work out the MPG from there.

I filled up 3 times consecutively at Shell and no difference other than a lighter wallet. All the hype around premium fuels may be true for some with premium cars but is pure BS for the average driver. I'm doing almost 15k miles a year and my aging Peugeot has no complaints running on garden variety diesel.

Q: Why do Asda think price fixing is a promotion when the price of crude is falling (again)?

Gosh you think we have it bad in the UK, Kuwait as put prices up 80%, how will they cope at 55cents a liter

https://www.theguardian.com/world/2016/aug/02/kuwait-announces-petrol-price-hike-of-83-to-55-cents-a-litre

For once a correct statement - homologation testing is done using the best possible fuel - for a reason ...... to get the best possible results

BUT - durability testing is done using the worst grade fuel for a particular market - again for a reason ...... to protect the product!

EliTom

Just about to do a sponsored road trip from Lands End to John O'Groats and back again for Guidedogs, this'll help!

He's right about the short distances not being good for diesel. I had a diesel c-max, in fact two both 1.6tcdi, the economy wasn't that great and nothing like advertised especially round town. In fact I recently swapped to a 1.2 tsi petrol and get much better economy round town and slightly better on longer journeys. I have a fairly large Skoda Rapid, just slightly smaller than an Octavia- get a Fabia, Polo or Ibiza and it should be even better. It performs as well if not slightly better too. Mostly on supermarket fuel too!

My Galaxy struggles a bit with Asda diesel so we have to use Redex occasionally or Shell V-Nitro to stop the injection flaps gluing up and stalling the car. Twice had to have an expensive special part replaced at garage due to this. To be fair I don't think its exclusively Asda, and I think the Galaxy is more choosy about its fuel than our Renault which you can throw anything in and it doesn't mind.

Again - factually incorrect. How can it cost more when it gives you 9% better fuel economy for a 7% increase in price? You are a net winner.

Refer to post #29.

Who has a seven year old Golf?

Says someone who refers himself as the "Illuminati".

Bit tricky with a visually impaired wife, 9 year old son & Guidedog! Looking forwards to it though :smiley:

Have to agree , years ago my driving instructor advised never to use supermarket fuel - false economy

Typical supermarket announcements to attract more custom for their stores, of course you might save a few pence initially but do you even think other supermarkets will just sit back without matching it.

I shop at Aldi and save a hell of a lot more than I would on fuel, plus the garage I use is one which is not out my way, is family owned, and diesel last week was 107.9, and I don't need to queue for 10 minutes to get it

**** off Asda for wherever I go, the prices are low, that's Aldi price *Dink dink*

Our Asda store here in Pershore doesn't sell fuel, so I popped round to Morrisons and got some at this price instead. :smiley:

Voted HOT, HOT, HOT, anway. Always needing fuel sooner or later. Who knows, I may be near an Asda store next time that does sell fuel

When does this end?

The fuel is safe! It is of minimum quality/grade, is okay for most vehicles in the UK

My average experience of 10 years of driving:
1 tank Supermarket fuel ~ 550miles (always mix fuel, different additives, all clean)
1 tank Esso/Shell ~ 600miles (worth it for motorways)
1 tank premium grade - 630miles (not worth it)

It always annoys me when people speculate about supermarket fuel and its quality based on idle gospip and passed on information. Anyone that works in or near a fuel supply depot will confirm the number of different tanks that fill up from the same supply. I worked near a texaco supply depot and different tankers for different companis were always filling their tankers.
Supermarkets offer cheap fuel, not because of the quality, but because they are not tied down to the same supplier and can shop around for the best price. So one week they may purchase several thousand gallons from Texaco, and the following week it may be Shell.

​Will do

Thanks :smiley:

Come down from £106.7 to £105.7. What a fantastic deal. Come on people, wake up. It's less than 1%.

My BMW motorcycle will run on ordinary unleaded or the premium stuff, it detects knocking when standard fuel is being used and retards the ignition timing to suit the fuel.
I suspect many modern cars do the same.
The effect is noticeable and the engine feels smoother and accelerates faster with the premium go juice.

Drives a "hot hatch", uses mediocre fuel. Kwality with a kapital K!

Also - cheap mass reared overcrowded chickens sold in some supermarkets with hock burns on their legs also have to pass EU regulations , doesn't mean they're as good for you and quality meat as a free range organic chicken . I don't buy organic chickens , and I don't buy premium diesel , just standard diesel but not from a supermarket .but I buy decent chicken not value chicken . Point I'm making is chicken is chicken fuel is fuel but there is a difference in quality .

A house could be worth £600k. A full tank could be worth £60. A big difference don't you think?

Why people are so keen to save a solid 100 pence is beyond me

Thank you for that clarification... :confused:

:confused:

I think the point he is making is he can 9.5% more off only 2% cost with regular.

TBH I'm amazed at his figures and be interesting to find out what he drives. Turbo petrol are usually benefit most from higher grade fuel. Be interesting to see some figures for some hybrid cars that use the engine for electric generation.

All modern engines are certified for mpg and CO2 in the ECDC lab tests on the best fuel available (to give them the best chance).

Not sure what a house is worth has anything to do with it!
My biggest expenditure over the year are in this order. Petrol, food, holidays, council tax.

Yes I grant you its not a huge saving and driving slower will save me more, but it's still a saving. :smiley:

0.25% on 600k is £1.5k. 1% on £60 is 60p. People getting too excited to save 60p on a tank, as previously mentioned by many on this very post.

:neutral_face:

Giraffe.

Yes that has nothing to do with anything as well.

Why pay 8% more for 5% more milage for him buying premium over branded regular. That makes no sense?

He wouldn't: he'd be paying 10% more for 14.5% more mileage with the cleaning and performance benefits chucked in for free.

A mortgage maybe but not what the house is worth. The whole point is is still a 1% saving.

Which is still 60p...

But he is only paying 2% more for 9.5%. How is that not better!? :confused:

Cos it excludes the performance benefits

31 extra miles is 31 extra miles.*

*Will vary depending on car mpg and driving style and conditions. :smiley:

Well as most who have posted on the thread either they see no performance benefit or are not in the situation to use it then paying 8p per/L extra is not worth it.

.
But others have. Again one is a net winner if they paying only 7% extra to get 9% better fuel economy - there is NO extra cost, is there?

This is a deal?

Ah yes, because I'd trust some gullible fuel-obsessed know-it-all on HUKD more than the manufacturer of my vehicle, who recommend standard unleaded...

You drive a hot-hatch for which reason? Performance or to look good on an Asda forecourt?

Shell might sell better fuel but they are a bunch of sharks. I was heading home late one night and my car was running on fumes. I had approx 5 miles to go but had already been running on 0 miles estimated range for about 5 miles. I spotted a Shell station so pulled up just to splash and dash to get home. Took in 6 liters ( so a bit over a gallon) and continued on my way. Didn't make it, ran out of fuel after 4 miles, less than a mile from home. My car does 45 MPG, so no matter what that extra 6 litres should have got me home. Can only assume the pump never actually delivered the fuel, or there was 6l all over the forecourt. After getting a tow I filled up my 52 litre tank with 56 litres of fuel at Sainsburys later that same day.

Shell aint ever seeing any of my cash again.

Ps if you're wondering why I only took 6l, it's because I only had some spare coins in the car and my wallet was at home ... took as much as I had the cash for.

My commute is country roads. Gets boring in a Fiesta.
Used Shell performance fuel for the first month of ownership after having the same mentality as you. Realised the economy gains were negligible. Now she gets a once per two month 'flush' with a premium tank.
Queried the manufacturer at the last service and was informed day to day running does not require a premium fuel.

Edit: Also, would be interested in knowing what you drive to have this mentality?

wow, they've lowered it to the price that it was a few months ago. what a bargain!

Supermarket diesel gunks up your fuel supply. BMW 320 diesel. Used supermarket diesel exclusively for about 18 months. Started having engine management warnings. Feared something expensive, put car in garage, received phone call from mechanic telling me to stop using supermarket fuel. So there's certainly something it does for him to know I'd been using it. Had fuel line and filters cleaned/replaced. Now use only 'garage' fuel, not necessarily shell, esso or bp. Car runs and starts better and economy has improved by about 2mpg on the same journey.

Supermarket diesel lacks some additives that are added to premium fuels to improve cold flow. That's a fact. Everyone should realise that you get what you pay for in this world. I'm not interested in defending this, it's purely my experience. I work for neither a supermarket or a fuel company so I have no interest in it either way.

Would I still put the odd supermarket tank full in if there was no other fuel nearby, yes of course I would.

But continuous use of supermarket diesel gunked my car up, fact.

How much do you people normally pay for fuel , this is expensive, i thought it had gone up...

this is cold unless im missing something ??

Fuel is never a deal, even if it went down to 90p, you would still kill any savings if you bought a single undersized mars bar from the garage when you paid.

I don't think think there is any evidence at all to suggest that supermarket fuel is detrimental to our car in the usual course of matters, very occasional contamination aside, and this article and the one it links to suggests the same
http://www.motoring.co.uk/car-news/is-supermarket-fuel-bad-for-your-car_65626

Sorry mate, i never said it was 90p a litre, just that if it was it still wouldn't be a great saving,

This thread is not about motorway prices, its supermarket so i cant see that the price of fuel there is the critical info i am missing, i was thinking more along the lines of it being hiked before hand or that you get some mega free gift or other benefit for purchasing it that actually makes this a good deal....





And if you are buying fuel on motorway it fair enough its expensive, but a normal garage o.0 as i said seems high to me - i saw it at this price at the garage and though fuel has noticeable gone up again.

Personally I stick to ESSO fuel, because in my experience (my car - 2015 Polo GT) it lasts longer then even the other branded fuel.. As it 's now the summer I get around 450-480 miles on their standard fuel.. I think if I put their Supreme I would hit 500+ but it's expensive right now unfortunately (around 120p or more)

Forget paying inflated price for premium fuel, just fill up at ASDA and every refill add a shot of Millers Eco Petrol or Diesel to keep your engine clean, improve power and reduce emissions, essentially the same stuff they put in premium fuel but for a fraction of the price. I've used it for over a year now and swear by it.:wink:

Simple it's 10% more for premium compared to THAT forecourt BUT actually more like 20% to the supermarket. Look at the basic numbers around you rather than create stats for others. P.s. I drive economically too, slow acceleration whenever possible, engine breaking, anticipation.... Hence good miliege with dodgy vw scandal engine :laughing:

Calm down, sometimes it's worth premium especially with vouchers offers etc but not always. Now, deals like this are much better, just compare cold vs hot voters for this thread.

Don't forget to add on the £1 charge from Asda if you pay by card.

Is it? Merely using a national average, premium is 8.65% dearer than supermarket, before you take into account Shell discount vouchers via its Drivers Club loyalty club and before using a cashback credit card like Santander's 123 card that offers 3% cashback on fuel.


This is a non-deal.

The Last time I put-in Asda diesel in my beamer... an error message came up immediately, and my car went into 'Safe Mode' restricted to a max speed of 50 miles/hour. Took the car to a trusted workshop (Bosh), they said because of low quality fuel your car's "EGR Solenoid" has fried. Don't really know what that is but it took £350 to replace and flush the tank.

Moral of the story:: Stick to Shell or BP and never ever put in supermarket fuel - cold.

For a third time, all modern engines are certified for mpg and CO2 in the ECDC lab tests on the best fuel available, i.e. RON 99.

Our resident Ford lawyer has appeared...

Okay sure, but let's not duck the question?

I only come in the supermarket fuel threads to see the doomsday myths pedaled by premium fuel enthusiasts . And as usual we are not left disappointed . We have people in here who have literally swallowed the Shell marketing spiel and treat it as gospel . We had religious extremism ,now we have petrol station extremism , committing a supermarket petrol jihad soon at a forecourt near you .
Id probably rather not trust somebody who essentially copies and pastes their information from other websites with no original analysis or commentary of their own , that course of action may well be questionable in the eyes of copyright law .

I'm still on my Golf R lease.

Despite the fact I have been using V-Power for almost ten years and calculate manually my MPG against what I actually pay and what mileage I have done.

Try harder son...

and yopur point is ? ...

EliTom

A car which has a specific requirement for 98 RON fuel. Sigh. Are we done here?

You have a car which requires premium fuel hence you use premium fuel.

Most other people don't, hence they don't.

Let's wrap this up.

Did you used to use shell optimax as well when that was what they called their increased RON fuel? Because we all know what the various independent tests found out about that stuff . And we all know the subsequent action the ASA took against Shell for their marketing of that fuel

Have you heard of the placebo effect ? . You've previously alluded to the fact that you modify your driving style when using these fuels because you believe that they provide increased torque . I wonder ....

Take a breath, look at what you are writing and not reading

You are entitled to your opinion, so are others, as the gentleman above points out you are approaching preacher level, this is a forum for deals. You have your opinion and a sizeable proportion have our own

For anyone else who is pedantic , work out how many pennies per mile and make your own mind up, as we live in different areas, different vehicles and cost of fuel

I think this is a great deal for the moment, if the main forecourts lowered their prices than it's also a no brainier to jump ship. Without competition in a capitalist system, prices will just rise with any excuse and no real justification

Good for you mate! I am just not risking Asda again with my BMW and prefer Shell. Though I do, occasionally, use Tesco petrol in my wife's Toyota Yaris which runs fine. Depends on the car, I guess.

I pay with debit card and £1 charge shows on my bank statement separate from the fuel costs, morrisons does the same.

Something not right with that then - I'd ask your bank.

What a load of rubbish, it all has to meet a EU standard, if your car engine packed up, get a decent car in first place, nothing wrong with supermarket fuel, Ive used it for 15 years plus and never had an issue with it !

exactly - some folk on this thread are talking complete BS ....

and yes I know - engines are my job :smiley:

EliTom

I hope you guys aren't SERIOUSLY believing that I filled up my fuel at ASDA and it literally destroyed the engine?

If so, that's a bloody impressive lack of sarcasm-detection.

actually not refering to you ... just some others who thisnk they were quoting so called facts

EliTom

Ah ok, think the guy you quoted was though! :stuck_out_tongue:

"Lubricity" eh?
Cool. :laughing:

​Anywhere from 52-58mpg.

Cobblers!

Yeah.
Cobblers!
It wouldn't have got that far.
I filled up at ASDA and all my tyres blew up. :confused:
And all my springs went "Boing"!

Even some things that wern't even springs went "Boing" too.

Careful bigraz69, you might get accused of having an impressive lack of sarcasm-detection, :smiley:

who cares mate, keep lovin your cheapass Adsa fuel for your cheap car living a cheap lif......

That's a shame because you'd need unleaded.

I used on a Golf V 1.4 TSI and I still use it on a Honda SH300. All modern engines are certified for mpg and CO2 in the ECDC lab tests on the best fuel available.

When did I say that I actually modify my driving?

Yet this isn't a deal...

A deal is an agreement on a price for an object or a service etc. a deal does not mean it has to be reduced in price.You can deal cards you can have deal furniture you can deal in antiques but nowhere in the English dictionary will you see it saying for a lower price than normal.

While premium fuel with its increased cleaning will help it is more likely an internal contaminant leak that is likely ongoing. This means at some point regardless of fuel used it will happen again.
I would either clean it on its annual service yourself or get it done at a garage. It should take a mechanic 20 min of chargeable time and £5 for the cleaner so £25 to £55 depending on the garage.

you said

"False economy - you'd better off filling with a superior quality fuel given that Asda fuel is a much lower grade. Shell V-Power Nitro Plus, for example, has higher octane, so it gives more torque at low revs and more power at high revs. If you use the greater torque at low revs to upshift earlier then you can enjoy upto a 10 per cent improvement in economy. That pays the extra cost of the fuel. The other benefits of a clearer fuel system (valves and injectors) comes free of charge."

Then later went on to allude to getting 10% increases in MPG from your premium fueled car . Seems reasonable to me then to suggest that you are practicing what you preach . That being said it does not prove that it is the premium fuel that is causing the increases in MPG . I'm sure if I did a test with my supermarket fueled car first driving it with a heavy right foot , then driving it in the most economical way possible I would see increases in MPG as well . If you are having to modify your driving style to see those MPG gains(in the belief that you have more torque at lower revs so are shifting up earlier ) then it is obvious what is giving you those gains

Lets face it the torque gains are going to be negligible . I mean the fifth gear test using their gti fueled with different fuels showed us that the overall HP gain from non premium to the best premium fuel is at best 2% . A handful of increased HP is hardly anything to write home about sat in traffic on our over congested roads .

Big deal. :smile:

O dear!
I've hit a nerve there. LOL
Of course YOU wouldn't be "cheapass".
Not you, who uses HOTUKDEALS to get "cheapass" deals.
Thank you for proving me right. ROFLMAO :smile:

Yet people are waxing lyrical on here about saving 1p/litre? If I am not paying more for increased MPG and better performance, then I'll stick with what I know best. You are of course free to do with what you like.

im guessing because you only replied to that part of my post that you do alter your driving style . In which case imagine the money you could save increasing your MPG by driving with a lighter right foot and using cheaper fuel .

Of course you would have to do without the "increased performance" 2% at best lol

Again - only you think this. I don't need to alter nor have altered my driving style to benefit, but naturally, keep beleiving what you think you have read and/or understood.

So your claiming that fuel efficiency is increased by 10% , just by using premium fuel with no alteration to driving style whatsoever . If so then yes thank you very much id rather believe facts verified by my own experience VS some fairy tale you seem to be trying (with little success) to peddle

You've not once provided any facts in rebuttal to mine . Which is a clear sign of a weak argument .

Well done. Took you a couple of days to work that one out.


I'm not the only person who has also benefited from this, dear.


Wrong. I've pointed them out repeatedly. I can't be bothered to repeat myself to someone who cannot put the effort to read the whole thread.[/quote]
Try harder next time...

Try harder next time...[/quote]
Chucked a tank of Shell Nitro+ into the Pug today, drove to work exactly the same as always. Cruise control at the same points, same amount of throttle, same amount of gear changes.

The result? 2MPG increase!!!!!!! Over the moon I'm gonna save loads!!!!

... Nope, fractionally more throttle response, but yeah, 2MPG gains...

Not going to work instantly after one tankful. You need keep using it.

Try harder next time...[/quote]Lol your attempts at patronizing tone might actually be insulting if you had proven yourself as posessing any intelligence . Instead they look like rather futile attempts to undermine my arguments without providing any factual basis .

Thus far all I have seen you point out is that you have well and truly followed the shell marketing spiel about their premium fuels . And you have the ability to copy and paste word for word someones opinion from another website .

Even to the point where you believe that your 10% increases in MPG are just down to the type of fuel you use .

Either way the topic at hand . It seems the heat this deal has attracted speaks for itself . Why not post a deal with you special V power fuel and see the heat it attracts ?

Looks like you lack some given your spelling.


I've proven nothing but facts. Are you still trying to tell me supermarket RON 95 is better than Nitro+ RON 99? Are you?


Given that I have used both Optimax, Nitro and Nitro+ for a decade with multiple vehicles including motorcycles and noticed the performance differential and the improvement on mpg. I always base these on tank full to tank full checks since average mpgs from trip computers are notoriously optimistic.


Whom? Honest John? Deary me, really?


So an independent motoring journalist who has a Q&A with readers who themselves point out the benefits is also rubbish, yes? OK...


Yes it states that most people are blind and think that a 1p/litre discount on supermarket fuel is a "deal".


a. I don't need to.
b. A fuel price is not a "deal"

Being as you claim to only use premium fuels for a decade with various vehicles how can you notice the difference. I think you killed your argument there.
By virtue of the dictionary definition any agreement between buyer and seller is a deal, may not be a good deal but it is a deal.
P.S. As I stated before I did get improved MPG going from Tesco to Shell normal so didn't see the benefit of going for + fuels.

Having used company cars where other people have the same car on fleet where they have used a supermarket fuel and/or comparing it to true mpg figures published on websites.


This is neither a "good deal" nor a "deal".


Congratulations

Maybe the same cars but the feet and the mentality are different and as for your response comparing with true MPG figures on other websites then you would have noticed the wide range of figures for the same make model engine that are published.

I used a Gaussian average to calculate my mpg against the others.

P.S. Use your dictionary for a definition.

Doesn't matter what average you used it's still a load of horse manure.

Thank you for your insightful knowledge!

Interesting question.

Would you use regular 87 (91RON) if it were available here and was cheaper? (I know you won't m5rcc)

It's probably a good thing we don't have the kind of choice they have over the pond. 87, 89, 91, 93/93.5, 100.

Many places only have 91 as the best available (95 RON). Although many are dropping 89 to stock 93/93.5. (98 RON). Most places have 3 grades available.

It wouldn't come here as it wouldn't pass EU regulations.

There is of course E10 RON 95 in Germany for example, but, even though ethanol can improve the RON, its impact on the environment is debatable as vast swathes of virgin rainforest in places like Indonesia are being ripped out and replaced by palm oil plantations that actually has an adverse effect on CO2, as well as on a lot of endangered species.

Funny that I was in America 3 months ago and I only saw 2 grades of fuel and just for good measure went onto a site that said 91, 95 and lead replacement at 96, so where you get all those different rons from I don't know.
Lets leave it at that now shall we sick and tired of all your nonsense answers.

Not sure why the attitude but it was a question not an answer. Would people use cheaper petrol if it were available. It seems more useful and constructive than what you posted over the last few pages.

I'm guessing you were down south? 93/93.5 accounted for over 10% of gas (petrol) sales last year. They seem to sell it more in the northern states. Generally where there is a large uptake in performance European and Japanese cars.
VP100 (or Street Blaze) depends from state to state. Finding it at the pump in places like California is pretty easy. Others finding it in a 5 gallon can is pretty hard.

Anyway the whole point of the question was if there were a cheaper choice would you take it if your car would run on it.

Oh wow I made a typo the sad thing is , if that is all you can pick up on then that right there is validation of the merit of my arguments thank you .

For the record I am not saying fuel from any source with a RON of 95 is "better" than fuel with a RON of 98 with additives . What I am saying is given that the evidence points to increases in HP of 2% at best , and extremely modest increases in MPG the extra 10-15p a litre is just simply not worth it . I certainly call BS on your claims that it"pays for itself" But then if you think that it does good luck to you . I suggest hunting out a deal for a decent calculator because yours is obviously knackered .

As for your claims to have been using premium fuels for 10 years . Okay if you say so , I dont believe it . But then that right there is not the matter at hand .

I am glad you have finally admitted to copy and pasting from another source . Your inability to add any original comment or input on those paragraphs you have lifted word for word from another source display the intellectual credibility of your arguments . Might as well have posted word for word extracts from the shell V power leaflets you must carry in your car to try and convert any infidels you come across ...... Oh wait you did that as well .

In that decade (yeah right) of using premium fuels , particularly during your usage of shell optimax (98RON) have you never come across the Tesco momentum (99ron) fuel . As it happens Tesco was selling 99RON fuel in the UK whilst your beloved shell was still only offering 98RON fuel as its best . As others have just pointed out , comparing other vehicles used , run in by and owned by other people is not a sound methodology for comparing MPG from different fuels . My version of driving with a light right foot may well be entirely different to your version of driving with a light right foot .Also if someone is driving a car that has not been properly run in , or if your car has not been properly run in then the results are going to obviously vary . Even usage of different engine oils , lacklustre attitude towards basic vehicle checks like oil levels , tyre condition and pressures is going to lead to variations in MPG produced by different cars . Clearly someone who is a motoring enthusiast like yourself (obvious from you caring so much about what fuel you use) You are going to be checking things like tyre pressures more often than someone who just sees their car as a means to get from A to B and just chucks whatever fuel is cheapest or from the nearest filling station


Ahh the sanctimony continues with you thinking that you know better then all the users who have given this heat . Anybody could claim that about any deal on this website . Including ones contributed by yourself . But the fact remains what people consider a deal is represented in an agreed format on this website . And that format is with the heat that a deal gains .

PS if you ever sell your shares in shell , be sure to let me know , I might buy them off you

I wonder if any racing teams use asda fuel...

Ah yes, because every car on the road requires racing grade fuel.

It only validates that in your mind.


Which evidence?


In your opinion


Given that it does you are entitled to believe what you want to believe.


Given that you have an "unknackered" calculator, please work it out for me: Last run was 33.1mpg and I paid 120.9p/litre for Nitro+ when unleaded was 113.9p. You already know I drive a Golf R.


Again, who cares if you believe me or not? Are you a judge?


When did I do that? I suggested Honest John, not that I copied from him. You did that...


Evidence please...



Evidence please...



Who said that? I know of it. I don't use it because it's not as good as Nitro+ because Momentum does not have the additive package that Shell V-Power Nitro Plus contains.



No Tesco near me that had it, so irrelevant.


Plural? I read that only one person mentioned it....


It was for me at the time. Again, all modern cars all modern engines are certified for mpg and CO2 in the ECDC lab tests, but don't let that known fact cloud your judgement...



Yawn - this fleet of cars were all maintained by the same garage, so your pathetic observation of tyres/oil/age of vehicle is irrelevant.


I already do that. Next!


Oh dear. Just because a "deal" has heat, doesn't mean it is a "good deal". If you really think that saving 1p/litre on crap fuel is good, then good luck to you. It's ironic, given that at the time, this price was not the best price available (according to petrolprices.com).


Yeh, cos a second hand iPhone 6 for over £300 is another great "deal".


Oh you are a financial expert as well! Multi-talented aren't you? :confused:

Just going to put this out there... You boys have way too much time on your hands :wink:

hahahaha!.. well said.

Always for people who need to be corrected...

So is this the summary?

1) Premium petrol probably has a better cleaning package which helps keep the injectors and valves cleaner.
2) Premium petrol may give you an increase in HP but it's very dependant on car
3) Premium petrol may increase your mileage but is very dependant on car
4) Premium petrol may give you a mix of 3 and 4 but it is very dependant on car
5) Premium petrol may give you no noticeable increase in HP or mileage
6) Premium petrol won't give you less HP
7) Premium petrol may decrease your mileage but is very dependant on car
8 ) Premium petrol is more expensive

Did I miss any?

Someone said point seven?

The evidence on 2%increases in overall HP are from the fifth gear test with different fuel types . the evidence on the increases in mpg being modest is from spending many hours reading car forums and sites like HJ . Ive never once seen any experriment that has reliably produced an mpg increase of more than 6-7% the average increased cost of premium fuel . I have however seen many people produce mpg increases in the 10%+ range by modifying how they drive . which was why I suggested this to you . the placebo effect as it was . Whereby you believe your car has more power so you drive it slightly different producing the mpg increases you see . you even alluded to this before backtracking and instead trying to implausibly suggest you got 10% increases in mpg just from premium fuel .

Again how have you compared this ? have you used supermarket fuel over a given length of time then then used premium in your own car over the same length pf time . driven the same . on the same roads with the same configuration . Because if not your numbers are pie in the sky stuff and certainly not arrived at through emgaging in any decent experiment method

So you are now claiming to have not copied and pasted directly from other sources with providing any additional commentary or input of your own . ok well I shall not be wasting my time proving this. Suffice to say anyone who has read from the start will know what I mean . and those who have not can go back and read then decide for themselves

So even before shell v power ntro was released and the premium offering at shell was optimax at 98 ron you did not use tesco momentum with 99 ron . but but following your warped logic you could have got increased mpg from it and it would have aorked out cheaper . How convinient that you prefer shell because of the "additives package" . That really is not doing anything to dispel this idea that you are somehow connected to shell marketing . Do they pay you 10p commission for every post here or something .

I find it interesting that these super additive packages are not sold seperatly . Its almost as if its a marketing ploy to get the naive to part with their cash ...... It seems to be working


See this is why I have issue with the methodology of your experiment the results of which you are using to make grand claims such as 10% increasew in mpg just on fuel type alone . Yes the fleet of cars all got "maintained" by the same garage . but lets be honest here all that means for company cars is a 6 month inspection and a service every 12 months . I reiterate my point . unless the cars are run in strictly adhering to the manufacturers instructions . and day to day checks are religiously adhered to then 6 months checks and annual servicing are going to lead to differences in vehicle's that do impact upon mpg . I fnd it astounding that someone such as yourself who purports to be a car enthusiast does not understand the impact an incorrectly run in engine could have on oil consumption and overall mpg from the vehicle .

Not to mention in your "experiment " The cars did not get driven by the same driver or other the same routes . We all know driving style and types of roads can have a massive impact on MPG . Put simply the methodology of your experiment is weak at best please try again with a more robust methodology

Banging on again about the fuels manufacturer's use when specifying the vehicles mpg in lab tests . Missing the point . I have not denied that you get modest mpg increases using higher RON fuel . but the mpg figures produced and the car manufacturers tests are not to determine the cost of fuel used over a given number of miles . The line you keep bleating on about these tests as if they are relevant to your argument thus showing your complete lack of understanding .Even if the premium fuel cost 20% more and only produced an mpg increase of 0.1% car manufacturers would still use then in these tests because the overall purpose of the test is to get the highest mpg figure for their promotional material .

Oh btw I am not a financial expert . Nor did I suggest I was . I do have some shares as part of my overall investment portfolio . And id be happy to relieve you of shell shares to add to that portfolio . I was not offering any advice or suggesting you should sell them .

Yes. I get less MPG. I don't think the engine adjusts to premium fuel at all so as premium fuel is less energy dense and I'm using it at the same efficiency I get less mileage. Also as it has no adjustment I will see no HP increase (measuring an increase on a 67hp engine would be difficult at best! :laughing: ). So for my tin can all I get is the cleaning benefit.

No but then their cars are specified to run on fuel with an increased RON .

I wonder if any racing teams pay for their fuel and pump it into their cars on a normal petrol forecourt like the rest of us though . Of course of you are being paid millions a year to put the shell logo on your car then its kinda a given the fuel you will have to use .

If shell paid me millions a year to put their logo on my car and exclusively use V power fuel I would happily pump it into my car all day long . Unlike some on here my premium fuel usage would actually be paying for itself then :wink:

Then you have not read them thoroughly enough.


Your statement makes no sense (aside from the spelling mistake). I said I get 9% better fuel economy for a 7% increase in price over supermarket cost.


Irrelevant in my case: I don't change the way I drive.


No - you misread what I actually wrote, as per the above.


I have used supermarket fuel before. On the rare occurrence that I'm nearing an empty tank and not near a Shell I notice the grogginess of the engine and the decrease in performance. And since the 2007 debacle, its not for me.


Of course you won't...


Indeed they shall, if anyone is still bothering to read this...


Again, as previously stated, there was no Tesco near me that offered Momentum. I am not going to drive out of my way to fill at Tesco.


I could say the same for you being an Asda employee. I don't because only someone who is extremely paranoid would think that..


They do sell alternatives/equivalents separately. But why use them when Nitro+ has them already?


You know the exact service schedule of that specific fleet? Another amazing attribute to add to your plethora of skills!


Some differences but negligible given the all the components and sundries used were exactly the same.


When did I claim or state that I was?


You are omitting that all drivers started from the same point, i.e. zero miles.


My experiment, my rules. Please write your complain to the ombudsman.


That is a laughable statement! They are completely relevant.


Think about why it offers higher mpg in the first place...


Not a Shell employee or shareholder.

Cars don't need to be run in these days as tolerances are so much more accurate than in the old days like when you had to hone in big end bearings, and metals were not as good as they are today, or the oils much more able to do the work required of them, but it won't hurt to be gentle with your car for a few hundred miles.

Very interesting.

How convinient that I have not found any evidence to corroborate your claims in my years of reading these types of sites . Yet I must not be readong them proper
That claim is certainly in line with your arrogant sanctimonious attitude

No it makes perfect sense . I have never seen anyone employing a reliable methdology see increases in mpg of 9% just from changing fuel type alone . As we will address below your methodology is not a reliable one . Do keep up .



Oh the great revelation . But wait a minute . Above when someone said they put one tank of premium fuel in their car and saw no increase you said that this was not enough they would have to use it over a longer period of time . One tank of supermarket fuel every blue moon is not a reliable enough basis to make assumptions about MPG


Makes sense
Perhaps one of the few sensible things you have actually said .

Oh come on we all know that is the service schedule for company cars . Ive had enough friends and had enough of my own company cars to know the score . Anyway its irrelevant unless you are suggesting someong come round to the users house and checked oil levels and tyre pressures every week for the users

I find it funny that you claim stuff like tyre pressures would have a negligible effect on the mpg . Do some firther research in this area because you clearly are clueless .


Giving others advice on small diesels and city driving . And your attempts to use buzzwords in order to look like you have a clue are two clear signs



I am not omitting that all drivers started at zero miles . I am in fact making that exact points . If all drivers got cars at 0 miles then it is possible that the cars you used to compare mog did not get run in properly according to manufacturers instructions . Particularly if they had them as company cars .

You do know about running in right ?

It is your experiment and your rules . but when you wanna try and claim 9%increases in mpg with such a poor methdology (cars run in and driven by different people over dofferent roads ) do not be surprised that people wuestion you . Given your methodology does not even stand up to the most cursory scrutiny we can dismiss your claims as total rubbish off the bat .

Unless you have any experiment you have conducted around MPG and fuel type that you wish to make known to us then I suspect this will be all .



No your continued repetition of this line without knowing what it is you are going on about is laughable .

Think about it for a minute . What are the purposes of the tests you are going on about ?

The purpose is to produce a measure of C02 Elemissions and a measure of MPG for taxation and marketing purposes .

If they can spend any amount of money to alter the results of these tests they will .

We know they will break the law to ensure a beneficial outcome from testing like this Just look at the TDI cheat device scandal . I would not be surprised if despite the rules car manufacturers used fuel directly from fuel companies that had been through additional qc . Fuel that would be expensive and near impossible for ordinary road users to source .

The laughable thing is you are attempting (yet failing) to convince me and others you know everything, yet do not have the courtesy to run a spellcheck on your rant. Can't take much notice of such people.

My Sierra diesel did over 1/3 of a MILLION miles, in 13 years on supermarket ( mainly ASDA ) diesel without me ever having to touch the engine.
However I did set the tappets twice but only because I had nothing better to do and I thought "there MUST be something that needs fixing." . :confused:
So, anyhow, can some "genius" please tell me when my engine should have blown up? :smile:

Oh. And my Mondeo, which has done the last 60,000 of it's total of 234,000 on ASDA diesel, still returns 50+ mpg and apart from having the EGR valve blanked off and a new alternator fitted, is fault free. :sunglasses:

Not attempting to convince anybody I know everything . Just pointing out the holes in your claims . Of which there are many

As for the spelling I was using a tablet hence the typos . But then here we are again ,no response to the substantive content merely pointing out the couple of spelling mistakes someone has made . We all know the type of people who act as grammar police ,and they are the people who have nothing substantive to add to the discussion . All youve done in your last post is make it look like you have no defence to the arguments contained within . I know you have not ,you know you have not . But is that what you want everyone else to think too ?

Anyhow assuming you have not got any more "evidence" of your 9% mpg increase I guess that will be all .

Perhaps next time come up with a more credible claim or make up more credible evidence to support it .

Had plenty of evidence. Sadly you had to resort to insults to get your invalid point across and have your messages deleted. Congratulations!

Yet to see your plenty of evidence . please do provide any "evidence" you have .

As i said so far all we have is your poorly conducted experiment .

Hate to break it to you . but to anybody who takes themselves seriously that methodology you used is far from credible and as I have explained countless times fails to take into account some factors that could seriously impact upon your results . I have seen high school science projects with better methodologies than yours .


Thing is if you would have just been honest from the outset and said . I think supermarket fuel is cheap id rather pay 10p a litre more for the additives and it does give me slightly better mpg . That would have been no issue . Its when you start making daft claims that people question your integrity

I get 3mpg more for 7% increase in cost. Not daft dear. Factual.

Get over it.

If you say so . Nothing really to get over everyone knows your theories are a bit wacky .

It's still 9% more than I'd get with Asda supermarket fuel. That's what you STILL fail to understand.

And you know this how ?

Before you point to your little daft experiment with company cars of which you had no control over the others . or your once in a blue moon tank of asda fuel I am looking for a credible explanation

Lower grade fuel as I've explained to you before. Every modern car is optimised for the highest grade fuels to give them the best results in the EC tests. They will work in lower grade fuels because the software adapts, but they will not work as efficiently typically giving 10% less power and torque and 10% worse fuel economy and emissions. But don't let facts cloud your superior knowledge...

Thats just random copy and paste from some website that you have not bothered to examine the basis of . Whats concerning is this sounds like a reasonable argument to you .

Go on then show me the reams of evidence to support this statement you have copied and pasted . Id expect loads of tests dhowing how premium fuel gives you 10%more power torque and fuel economy . As I said the fifth gear teat which was conducted properly by draining the tanks ahowed a 2% increase in power using the best premium fuel . Nowhere near your claimed 10% . Dont believe me ,their tests are on you tube for you to see . Take note mate thats how you do a proper experiment .

There you go banging on about the ec tests again thus showing your lack of understanding in their purpose .

Unless you have any actual evidence and not just something you have randomly copied and pasted without even giving it the most cursory examination I will be left to assume that you are actually a 17 year old insured for casual use on his dads golf match .

Im assuming you have no actual evidence so that will be all . Good luck in life not being able to question anything you come accross dear boy .

It's not argument. It's a statement of fact.


What is the purpose of an ECU with regards to fuel quality?


The Fifth Gear test is irrelevant. I'm referring to fuel economy. Not power. Another example of the failure to read and understand what I wrote.


Try Google if you don't understand it.

I'm neither 17 nor driving my "dads golf match".


I don't have the problem. You do. I will continue to use it because I'm a net winner by using it.

Again no actual evidence adduced .I have nothing more to say to you until you adduce actual evidence(not copied and pasted statements saying something ) from a properly conducted experiment that unequivocally shows using premium fuels "typically" gives you 10%increases in torque , power and MPG . I tend not to believe something just because its written down ,I prefer to work off proper evidence .

Net winner that cannot understand the difference between evidenced fact and a copied and pasted statement that he does not even understand . Sure thing ....Rock on tommy

Well summer must be over now,the price reduction lasted all of 3 weeks,it's gone up 1p again
must be the rise in the price of Brent crude

Great price now the others retailers need to catch up

​internal contaminant leak... Huh! Dude it was a newish 5 series, just out of warranty, when it happened. I've been using premium (Shell/BP) diesel for about a year now and my car never had a hiccup ever since. While easily managing 60MPG+ on average.

Like it or not, premium fuel is overall better for your car and returns more MPG. Cheap supermarket fuel might be OK for some, but it's definitely lesser of the two options.

Look who is talking, you the porky-cheepo King with 6000​ posts on hukd.. Huh! as I said no one gives a f**k about you, so keep on barking woof woof..

You lie like a cheap *og watch!
I have only a few deals on HUKD.
Is this your paranoia kicking in? LOL :smile::laughing::smile::laughing:

Just bought a Diesel car recently... how I wish the prices could be as low as they were back in the Summer! :disappointed: Brexit vote is going to hit us hard at the pumps now!

Plus the rising price of a barrel of oil.
