    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!

    Rated 5 out of 5 by from Sceptical I've got a Mercedes 270CLK with 14th on the clock, she was smoking when accelerating which I found very annoying. Someone mentioned putting a cleaner through the tank but I was very sceptical! Anyway as a last resort I put a can of this magic in a half tank of fuel last night and after getting to work this morning (30 miles) no more smoke!

    Rated 5 out of 5 by from Power back at last. My Mrs wrong fueled my Alfa several months back. After driving for a couple of days and finally realizing what had happened the tank was drained and refilled with diesel. Although the car was still working I always felt that there was a lack of power between 1000 and 2000 revs. I brought this product thinking it might make things a little better. I was wrong. This product instantly gave the car a nippier feel I even spun the wheels as I was so used to pressing the gas hard to get it moving. Now the pick up is instant and the car feels smooth at low or high speeds. I'm recommend this to everyone. It cost less than £7 so even if it doesn't work for you it wont break the bank. I'm going to add this every year at least to keep things working as it should.

    Rated 5 out of 5 by from it works I drive Focus tdci 1.6 90bhp with 91000 miles on and I became a little smoky when flat out up hill. I decided to give wynns a go and it works. I used full bottle with just a little bit more than half of tank. I have done just over 150 miles and I can see it works. Engine has better power and 2 out of 3 times it doesn't smoke. I believe it's too soon to expect full success but I can see the difference now. Also please read the instruction on the bottle before you fault it

    Rated 5 out of 5 by from Pleasantly surprised I added this to my 2008 2.0 tdi golf to see if it could improve the injector nock and overall health of the engine, I added it as instructed to half a tank of fuel and have now filled up again and can confirm the engine is without doubt running far sweeter, and is certainly a fair bit quieter, very pleased with the result and will be buying more.
