Try standing closer to a 250ml bottle. It looks like that.

I seem to recall when 5th gear put redex in the car it actually Improved the BHP. didn't say not to use.

misinformation tut tut.

I'll try and find link on you tube

great value good deal

The autoexpress article is a news story reporting on a Which? test published in 2009. This tested octane (petrol) and cetane (diesel) boosters. Octane/Cetane are essentially measures of how effectively the fuel burns. The conclusion of these tests was that the additives tested did boost octance/cetane, but that they made no difference to economy or emissions and only small difference to power for the petrol variants.

These are different products from the Redex here, which are system cleaners. The manufacturer website is rather vague about what the product actually does or what it contains.

Super premium fuels (v-Power, etc) are higher octane/cetane, and claim also to contain more/higher quality additives. There is a wikipedia article about v-power for anyone who wants to know more.

I don't see why 'newer' engines wouldn't benefit from using this, unless they are self cleaning?¿????

the fuel is the issue that leaves deposits and crap in your engine........so regardless of the age of the engine if your using the same cheapo fuel it will leave the same crap in your engine......

newer engines are more reliable and probably manage better with the dirt, doesn't necessarily mean they are cleaner inside.

​nice thing to wish on someone, thanks :smile:

First two things that come up with Google.

Fifth gear
https://youtu.be/VG3j0g88kXs

Fifth gear did indeed do another test as described earlier promoting redex but it has been picked apart by viewers and there is even a thread on piston heads about it. The show was allegedly sponsored by redex and the dyno graphs show that the dyno "tester" let up and didn't take the engine to the same higher revs before the redex was used which essentially "fixed" the outcome in redex favour.

Might want to check your facts... "Dramatically improved performance and mpg"?? They did a test on a car and gave it a full service and new spark plugs and commented that it improved performance by 5bhp mpg raised by 1-2 mpg (180bhp that's what a 2% gain and probably down to the service)? Is that a dramatic increase in your mind? If you actually look through the internet articles and find the video they had done 2 years prior all the evidence shows the stuff is as commented by numerous others "snake oil" and I know first hand it's not good for your car. Like I said before it "burns hot" talking to my mate about it today.. he confirms it burns much hotter than fuel to try and burn away the deposits in the engine and injectors and this is why it's not worth the risk of using as I found out it caused expensive repairs to my engines Injectors. But by all means call me a liar and use it.. someone will use it and seriously regret it. People are right.. just use higher quality fuel especially in diesels to clean the engine and prevent premature dpf blockages.

utter tosh, if used in the correct dosage it won't damage your car, even if a stronger dose used its unlikely to do so.

Better still don't be tight and pay a few pence more for the premium fuel and you shouldn't really need this anyway.

When using this my Mondeo diesel MPG is improved by 2-3 mpg ( according to trip computer).
Engine pick up is noticeably better when pulling away too - this is the main reason i have been using it.

I only buy it when its half price though ( £2 for a 250ml bottle )

Otherwise known as Snake oil.

If it's so bad how come my wife and I get much better mpg using it.
She has been using it in a Mercedes A200 AMG for three years and I have put it in my ISUZU D-Max for 4 years.
Also used in all of our previous diesel cars & pickups for a long time.
Hot but I'm not going on the goose chase.

This isnt right, 1 litre for £3.25 4 x 250ml @ £4 = £16 How is it 75p cheaper

So Ben you big tease are you going to give us a clue which is your local Tesco? :neutral_face:

Don't put any in your tank!! Word of warning here.. this stuff burns extremely hot to "clear" build ups. I used this in a Honda CRv diesel and followed the instructions.. it blew the fuel injector seals! Two close friends of mine are mechanics at different dealerships and both say never use this product! Likewise fifthgear did a review of numerous products a few years back including redex and they also said that it is not good for your car!!

REDEX is SOOOOOO BAD, that's why No store sells it, because it kills your engine, etc etc..
oh, hang on, it must be OK, as peeps keep buying it, which is why its still sold!!
Handy in older cars, 08 and going back... Cleans crap on the inside, same as what Shell V and BP Ultima do.....

Tesco Pengam Green - Cardiff has a few of these bottles, as I picked a few yesterday.

very nitro is great used it in my 1999 audio a4 , drove like new when using Shell fuel

thanks , use it in garden equipment and an old classic car

This stuff was popular in the 1970's, unless your car is decades old, not just new, it's not needed

This stuff is outdated and no longer relevant to today's engines, it's pure placebo effect and smoke.

Appears to be RtC on the shelf-edge label in the photo

If you have Costco membership and don't want to go on a wild goose chase, you'll get 4x500ml for £11.98 from 30Jan-19 Feb.

Calm down people its only naphta

I have never seen 1 litre bottles of Redex

£2 in Wilkinson's at the weekend probably national

Check your manuals for your cars. Most modern engines strictly do NOT recommend additives, and they can invalidate your warranty.

Thanks me later.

don't put a litre in your tank!
