    Rated 4 out of 5 by from Quality stuff Always get things that do what they are meant to unlike some brands,but early to know only done 150 now but engine seems to run better (42,000 mls) and but more oomph,probably be more noticeable on higher mileage cars but with trade card great value.

    Rated 5 out of 5 by from Immediate effect My 1.8 Mondeo has felt very rough and loud at about 2000 revs and I was worried that it might be something serious. After a bit of research, I decided to try the system cleaner. Within a few minutes, the engine was quieter and smoother. There has also been an increase of over 6mpg on average after only 24 hours. With the way in which the price of diesel is going at the moment, this small bottle will pay for itself very quickly.

    Rated 5 out of 5 by from Fantastic Result I have a Renault Megane 1.5DCI. It had been steadily performing worse and fuel consumption poor. It finally wasn’t able to get up a hill it had previously been ok with. I then started to see the warning on dash for injectors. I looked online at these products after being told to try them. The staff in Halfords Rhyl were as always really helpful. I must admit I didn’t hold out much hope that this would work and was beginning to think I’d have a large repair bill coming. Anyway , put one bottle of this in tank and put in 20 litres of diesel, after running through this fuel my car is back to full power and fuel consumption and running better than it has for a long time. Hope this review helps it certainly is worth trying for £7 it’s well worth it.

    Rated 5 out of 5 by from What a difference! I bought an 06 Pathfinder 2.5 TDI and was getting 28.6mpg combined. I bought this after not being able to find the one recommended to me, so have nothing to compare it to, however it made a noticeable difference. I'm now up to 33.1mpg. As it is an older vehicle, I was unsure when the injectors were last changed, but this seems to have worked. There is also noticeably better throttle response. I have now bought a second bottle and a spray can of the EGR cleaner, so will be interested to see how much of a difference that makes.

    Rated 5 out of 5 by from Wow!! After my diesel starting conking out and stalling itself at inopportune moments, I decided to ignore reviews saying these cleaners were a waste of time, and use this product. The difference was almost immediate. My 9 year old Auris is back in the game! It's also stopped the white smoke which made my street turn into old London Town on a cold morning. An amazing product and I would highly recommend!
