Tasted revolting. Voting cold.

Get millers from halfords, you do notice a difference in power and mpg.

I put some of this stuff in a Vectra diesel. Within a few minutes of starting up the engine warning light came on. Turned out one of the lambda sensors in the exhaust system had been damaged. Cost me £85 to get if fixed. Won't use this stuff again in any car.

Where?

Halfords are doing both diesel and petrol for £5 which treats 4 tanks

Tesco £2 each.... Not sure if it's still on offer

On the olden days I could see the use of this stuff, helped stop pinking and dissolve crud from old metal storage tanks. With today's fuel and delivery systems, at the forecourt and engine, I really don't see the need for this stuff.

Voted hot because it is a good deal.

Right what's the point

often £2 at Tesco

I put this in an motorcycle through the carb once. Had to re-ring the bike afterwards! Taught me about 4stroke engines though :smiley:

what about Forte stuff. More expensive but hear its really good. Especially the diesel ones for dpf problems.

Erm are we going back 30 years when fuel and oil was not at its prime...

Modern engines with modern fuel and serviced within schedules would not need this.

The dealer i use to work at flogged this stuff as a money earner on service although the manufacturer stated no additives at all fuel/oil must be used as it can cause damage, as found by above by others.

Was £2 in tesco Yiewsley last night so offer must still be on

millers and forte seemed to work better in my car.
forte was good for dpf but mine would get blocked up again not long after.

I paid £2 in Tesco also

I had a long talk with the AA man he said that this stuff wrecks the DPF systems on modern diesel cars. Modern Diesel fuels have lots of additives and they do not need this at all. He says to avoid this at all costs. His Ford Transit diesel had 2 new DPF systems fitted and Ford investigated the old ones and pointed at RedEx as the culprit that was corroding a component in the DPF filter. So on that advice I would not risk it as the AA had stopped using this when servicing their Diesel vans. Should still be OK on older non-DPF diesels though. The AA guy ran a can of "Wurth Diesel Additive" through my Vauxhall Insignia Diesel. It's about £15 a can. But the AA use that all the time to flush engines through. But modern diesels don't need it regularly.

Don't know if this works but I have a 10 year old car and have been using this stuff once or twice a year, from new. Never failed a MOT- I know modern petrol already contains lots of cleaning additives but £2-£3 a year extra isn't much even if it wasn't doing much.

This stuff does actually work. I failed my MOT on my audi which has dpf on the emissions part. Stuck a bottle of this in and a quick motorway trip and had it passed next day.

I also notice a slight improvement in my mpg whenever i use this.

My advice is that if you buy supermarket fuel (like i do) then stick half a bottle of this in ecvery few tanks or just buy decent petrol/ diesel to start off with.

A lot of manufactures specifically recommend that fuel additives should NOT be used at any time.
Just a warning in case you guys didn't know.

Upper Cylinder Lubricant - does Ann Summers sell it?

*tesco

check your asda, in mine in clearance section they had triple redex pack for 4.50, petrol and diesel versions same price

Reason(s) for failure
Exhaust emits an excessive level of metered smoke for a turbo charged engine (7.4.B.3b)

I dont do much motorway miles so i reckon the dpf was probably full of crap and just needed a motorway journey. Remember seeing the tester rev the engine and all this black soot coming coming out...

Like i said my mate suggested i put half a bottle of this stuff in and do around 40miles on a motorway at 60mph+ on low revs. It worked - had it passed next day.

I agree it all comes from the same companies. But the premium diesel at some petrol stations does contain added aditives which does increase fuel performance (i.e Shells V Power in my car lasts much longer). My point was that supermarket fuel doesnt have these and does burn faster.

So for me i either fill up on a decent diesel every 3-4 tanks or throw half a bottle of redex in when its cheap like this.

Cheers! Was curious as we have 2 diesels, one DPF one pre DPF never seen the dpf one smoke, the old one does when you boot it mind...

Just got 2 bottles in tesco £2 each

expensive parafin

Two things always make hukd kick off into mass conflict: redex deals and halal deals

it does work as it removes soot by hiring it octane level. ie: burns hotter, but it is only paraffin ok

I like to run this through mixed with a litre of 2 stroke oil and let it be for a day or so before a test. Not had a derv fail on emissions doing this.

I've always thought products like Redex were snake oil and unnecessary. I've always steer cleared of them. But this thread reminds me that I was looking at getting a Terraclean treatment for my car which is different. They disconnect the engine from the fuel system and connect it to a special machine which feeds it a special refined fuel which burns off any carbon deposits in the engine, including the O2 sensor and catalytic converter:

I read a lot of good reviews about it:

I was quoted £75 and think I'll go for it when I next get a day off work.

£2 in Tesco

Do not use on a brand new Diesel car!!!!!

Brought it for £2 from ASDA over xmas, to use on my diesel as I have reached 100,000 miles with a full tank, it turned the exhaust fumes grey and white when the engine was rev'd was a bit worrying, seems my fuel efficiency has improved a little. Will now how much after another 10,000 miles.

Interestingly you can improve fuel efficiency by trying to keep your rev's steady regardless of speed (obviously use commonsense with regard to speed) and on my car the sweet spot seems 1,800 revs

How do you actually use this stuff?i bought one a while ago for my diesel but haven't used it yet,

its paraffin or kerosene is what it is. its pink in the uk. a gollon will cost about £6 last time I bought it. this is a very expensive way to buy paraffin. it burns hotter. if you have seen a coal fire the soot is missing just above the red hot coals. that's the heat from the paraffin in the coal. its your money? check the label of both they are the same.

My dad used to use Redex in his 1960's Humber when I was a kid! I'm told by smarter folk than I that you get the same result if you fill up with a Premium Diesel like Shell V Power, once every few months.It just cleans any carbon deposits off the injectors.

​I put some of this in my fiesta, my house fell down :stuck_out_tongue:

I used half a bottle of this as instructed, but I am still constipated. Before you ask, yes I had a full tank as had just had dinner. Therefore, won't be buying again!

I added this to full tank of fuel. According to the mechanic these fuel treatments are known to cause damage to sensors.

£2 at tesco got one few hours ago loads left

Asda doing a three oack of these for £7 reduced from £12 at the mo. Picked one up yesterday from Clayton le woods branch
