Regular use of Redex helps to: Keep injectors clean. Reduce exhaust emissions + engine noise. Restore performance. Increase fuel economy.

I used to buy these normally for £4.00. It is a bargain for those who need it!

Diesel and Petrol versions were available at Gallions Reach (London) Tesco Extra. It could be nationwide.

The ASA considered that the claims of Cataclean were misleading.

3. Upheld
The expert considered that using a vehicle with a known and apparently unquantified problem was bad practice. The results showed that Cataclean had no beneficial effect on emissions. The expert noted the evidence did not repeat the decreases in emissions that were demonstrated in the infomercial. We considered that the claims were misleading.

5. Upheld
The expert advised that catalyst efficiency was established by analysing the exhaust gases entering and exiting the catalyst. He noted the submitted tests did not use that method. The expert advised that the product was extremely unlikely to survive the combustion process and reach the exhaust catalyst. We considered that the claim was misleading.

If you add this to a modern Diesel engine you can ruin it.

same price at asda

Have tried this in the past on a truck that was struggling on the emissions test;

Warm up engine, take fuel filter off, pour the diesel out (back into tank) put Wynn's Diesel Treatment directly into the filter. Start up and rev the knackers off it till the Wynn's has gone through. Drive to near MOT place. Remove air filter. Drive to MOT place. Truck passed. :p

Can confirm the diesel is nationwide, seen it in 2 of my local superstore's but the petrol was £4.00 in one store and the other store didn't stock it.
#12

Is the greased lightning stuff better than redex?
#16
Bought the redex petrol fuel injector for that price
#17
For those with Costco membership, it's standard price is about £14.30 (inc vat) for 4 x large bottles which are the equivalent of 4 x 2 of these bottles (8)

nice price. hot!

crap product,may as well put paint stripper in your car.

best thing you can do is stop buying poor quality fuel (i.e supermarkets) and pay a few pence more from bp,Texaco etc.

you'll save your car and money in the long run.


hot for price but not as a product

Any evidence for this? All fuel has additives in, this is just another basic additive.
#22
I have been putting Redex it in my 2004 VW Passat TDI for years and if it has reduced the MPG I would like to know how much more I would have got if I didn't use it in the first place as I'm getting extremly good milage (Well over 50mpg) for a car that has nearly 200.000 miles clocked up. Saying that I noticed when when My with got a Ford Focus 2009 TDCi that it says in the manual if an additive is used it would affect the warrenty?

lol BP is the best diluder (worst one) of fuel of them all... there is no quality at all they need to make money for the oil leakage they caused.

Modern diesel engines from around 2010 ish use something called a DPF diesel particulate filter in the exhaust. Using this product probably will not be an issue with older diesel cars (without DPF), but the more recent ones may have issues with the DPF vs. this product. I cannot find anything to substantiate this 100% though. I guess you could contact Redex and ask them if it is OK to use with DPF's as other manufacturers state clearly they are (But Redex do not). Personally I would avoid. After all why would you pay money to potentially knacker up your car? If you want to spend £2 on additive, just fill up with the premium diesel fuel. That way you can almost guarantee it won't cause any issues.

Really? Why?

I've used it in my 2010 Audi TT diesel and the engine doesn't seem ruined.

I know for a fact there is a difference in quality, that's from seeing test results. Supermarket fuel is fine, but its not as good that's for sure.

That is a fair point, although Redex is mainly kerosene IIRC, which should burn cleanly and not clog the DPF.

Normal, supermarket diesel has plenty of additives to keep your engine clean, let alone premium stuff, additional cleaners are not necessary.

I've just checked the (somewhat outdated) COSSH sheet on it and it's all just hydrocarbons (some with nitrate). Your DPF is fine and will not be harmed by this. The product is just a lighter fraction of hydrocarbons that will help to clean the coking you inevitably get on injectors with time. However the best way to get this off is by using the additives in premium fuel (and will be contained to a lesser extent in cheaper fuels). I find every 10th tank is enough to keep things performing close to optimal on my 08 diesel (usually run on normal Shell). The issues aftermarket additives may cause can be varied and unpredictable, sensors can be contaminated, catalysts may be affected, seals may degrade, diesel pumps may even fail (as they use the diesel as the lubricant). If they contain only hydrocarbons with maybe some nitrogens and/or oxygens attached you're going to be relatively safe unless you add to much. Anything else and the newer the car, the more risk of something going wrong. Obviously pump diesel can never be allowed to contain anything that could cause harm (even though it has been known to happen) so is your safest bet
