    Rated 4 out of 5 by from Redex diesel Works well with supermarket fuel that doesn't tend to have the cleaning additaves already added. Still cheaper to occasionally by a bottle of this than by more expensive fuel

    Rated 5 out of 5 by from Redex Not available in France where I live so need to stock up on the infrequent returns to the UK. I have monitored the increse in MPG using this product and soon recovers its cost.

    Rated 5 out of 5 by from it works I have been sceptical about diesel additive products that are supposed to give excellent results, so I think I should say that the Redex diesel treatment does work. My 2011 Volvo V70 Auto D3 (52000 miles) has, following a 2000 mile French trip in the summer towing a caravan, been giving poorer MPG (35/36 at best). After three tankfuls of supermarket diesel with Redex added it has improved to 42/43 MPG over local and motorway speed driving. The auto box changes up to a higher gear at lower revs and is more flexible. The engine runs quieter and just feels better to drive.

    Rated 5 out of 5 by from Works for me Used to get what I call diesel clatter in warm weather in my insignia ,so just thought I'd try redex , tried other more expensive treatments and they didn't work. But to my surprise redex seems to have worked !! No more diesel clatter ! time will tell u guess but for now it works

    Rated 5 out of 5 by from Good Old Redex I've started to use redex in my Lexus diesel, after 2 bottles of the stuff over couple thousand miles it's running better than it did when it was much newer . I guess at 103,000 miles it's just about run in now ! No more juddering at full load and very little if any smoking . No EGR or DPF issues at all , just runs like it should run at last !

    Rated 5 out of 5 by from It works and cheap This stuff works a treat and at a great special price...4 tankfuls for a fiver, brilliant. Redex has been around for decades and is well trusted to do the job well. I do not do a lot of miles now resulting in my diesel engine getting a little grubby inside. I could tell it was because the exhaust was getting a little wiffy. Now the Redex is being used my exhaust is getting sweeter and quieter. My car is running better now than it did when I bought it 9 years ago. A great product!

    Rated 5 out of 5 by from excellent product I bought online and it was ready to pick up within 15 mins. Redex has always been a great product for diesel treatment of cars etc. having recently purchased an older secondhand car I noticed it was producing a little black smoke from the exhaust.i purchased 2 bottles of 500 ml size Redex, each having 4 standard dosed of treatment. I initially put 2 doses into the fuel tank and what a difference it has made. My car runs smoother, no black smoke and around 4 to 5 piles per gallon now achieved. Brilliant, thank you Redex.
