Not everyone has Costco membership thou. For me to pay £33 membership, travel 35 miles each way to my nearest Costco and then have to buy a lot more of a product than I want, doesn't seem a good deal to me.

this v shell nitro?

500ml is 4 pack for £12 or just under in Costco

the 1litre bottle of redex petrol scanned at £3.50 today at the Tesco superstore in Stoke...bought it along win 2litre can of Castrol engine oil which was half price at £9.00

Does this even work?

the best is by BG.

Buy Millers oil and save yourself all the trouble...

​Been tryna figure if this is worth a try and some info on motoring forums indicated that this stuff ain't what it used to be in regards to strength. People accounted it to EU laws on harsh earth killing chemicals etc.

It was just thoughts mixed with anecdotal stories so take what I say with a pinch of salt I guess :smiley:

​Could you tell me what problems you had? Also, when you say 'modern', how modern? :man:

I've been researching this cos although mechanically I don't need it right now, I'd like to see if it'd help give me more power in the low revs and make my engine run a bit quieter. People on here have previously said not to use it in modern diesels so I want to be sure before I do anything as I have the worst luck!

I get more mpg and less engine noise so for me it works well. looks a good price too. :smiley:( V nitro at the pump is about 10p ltr extra x 50ltrs £5 ) that's why I use redex

By modern diesel I mean one with a DPF and controlled via various sensors and an ECM. My 2012 Insignia has had problems both pre and post combustions I've been told due to the way its driven, it does mostly motorway work but as its got 6 gears 70mph on the motorway is around 2000 revs.

I've had the DPF warning light on a few times (need to do a manual clean), had the pressure sensor in the cylinder go faulty 2 times (expensive to change as they're a combined glow plug/sensor unit) and an pressure sensor in the exhaust manifold changed due to being bunged up with soot, again because the engine revs never get high enough to heat the engine to burn off the excessive soot produced.

I always use the Millers in my diesel 2.2 Accord brilliant stuff been using it for about 3 years now.

Started using this last month as my car seemed to be drinking fuel. So half a bottle to £35 fuel later from empty/low tank and thinking sceptically off I drove hoping though for an improvement.......amazingly it actually works! I get around 20-30 miles more than I was getting before driving exactly same. in my experience it is worth using. :smiley:

For people think this will clean dpf's think again. I read that this product only is supposed to do its cleaning when the diesel is in liquid form ie before the piston side of the engine ie for the injectors. After the combustion when you just have exhaust gasses left the product is depleted, finished, no effect.

To clean dpf / egr valves/ turbo/ cat converters you need a product that starts to become active in gas form.

Placebo effect please continue for the masses.

I have this problem.. how do i get enough heat to clean DPF?? I find that if i dont warm the car up long enough it feels like the 'choke'?? Isnt working and car either stalls or I have to put my foot down and rev the car really hard to gt it moving!! Do i need to drive longer and harder to heat the car up?

​I know that and only mentioned it cause some folks seemed to think it helped

Depends how bad it is, in some cases the exhaust manifold and associated parts needs taking off and cleaning by hand. There are a few 'post' combustion cleaners out there that may be worth a try.

Since my problems I now drive the car (once warmed up) at 70mph for 5 miles every 3 to 4 week in 3rd gear, I was told by a local mechanic that this will increase the heat and exhaust pressure that will help with cleaning.

If anyone is interested, it is still available at Tesco... Bought some at the Tesco in Old Kent Road in London, yesterday... And plenty in stock...
