Redex RADD2201A Diesel fuel System Cleaner, 500 ml

Excellent product and great value for money. The quality exceeded my expectations and it arrived quickly and well packaged. Very easy to use and exactly as described. I’ve been really impressed with the performance so far and would definitely recommend to others. Will happily purchase again in the future

Started using this a couple of years ago - I have a diesel car that is over 9 years old and has done 70,000 miles. There is a great debate online as to whether these additives actually make a difference. For me, it seems to. I typically only use supermarket fuel and as the engine is getting older, it seemed that I wasn't getting as good fuel consumption. For me it seems to help with the efficiency.

I first started using this on my Skoda Fabia Monte Carlo. The Redex upped my mpg to almost 60. I now have a VW Golf GTD 184 and I was unhappy with the mileage. I realise that this car has 184 BHP, but I was only getting mid 40mpg-maybe 47/8 on a run. Started using this a few months ago and my mpg has now gone up to almost 52mpg and the car feels a lot peppier (although the acceleration without Redex is still very quick!). I usually get around 400/430 miles from a full tank but recently I got over 480 miles on a tank. So yes this does work, it has improved my mpg and the engine feels better. The only downside I can think of is that I have had to go online to get any as I can't find it on the High Street. I used to get mine from Wilcos, but they've not had any for ages. I would recommend using Redex.

All good

Bought this for my 4X4 diesel abroad. The standard where I am is euro 2 diesel, so often get smoke from the filter when it does an auto regen. After using this, and I have used others, this stands out so far because I get a little more mileage to the gallon and there hasn't been an instance of white smoke far longer than usual. 4 applications in this bottle, so well worth it. On for £7.29 for 500ml. Should keep you going for a year's driving.

Very good

Added this to my 2.0 TDI VW ... as prescribed - does it work? Well sort of .. Car does certainly feel perkier when I add this to a tank. Just feels more responsive but when it's diluted with fresh diesel that perkiness goes away. Maybe just an octane booster - I can't say if its cleaning the injectors. I give it 3 stars for the fun factor it gives when driving but I can't say that it is cleaning car engine's insides. Would I buy another bottle .. ? yeah, why not?

Excellent product and arrived in good time . Not sure if it is in the mind but the engine seems to running better than before delivering more power and better mileage. It certainly isn't blowing black smoke under load as it was before using redex. I now use this with premium diesel which will hopefully further improve performance....time will tell.
