    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.

    Rated 3 out of 5 by from Hard to check It is hard to make conclusions, because you can't really check if fuel valves have been cleared. You have to believe what is stated on the label.
