    Rated 5 out of 5 by from It works This does work after putting this in my Cooper s my mpg went up by 7. With shell optimax and a run on motorway my car mpg is constantly better. I definitely recommend anyone to use this. Car performance feels more responsive.

    Rated 5 out of 5 by from does what it says on the tin I have used this on a few cars over the years and it makes a big difference to the mpg and the engine does sound alot healthier. I put this into a nearly empty tank and then fill up using shell v power. Then take it on a 30-40 mile run keeping it in low gears and revving high. It cleans the system out

    Rated 5 out of 5 by from jag 35 year old v12 cured miss fire Could not believe how well this product worked. My car is 35 years old and suddenly developed a miss fire. The garage was not able to pin point the fault. So I added the product before filling the tank with fuel. I then took the car on a run on the motorway running the car at high revs 4000 rpm. After 10 miles I noticed the car had improved. 3 miles later the car was firing on all cylinders. After traveling a further 100 miles the car really improved. Now getting some amazing performance from the engine. Dont expect instant results as the product needs to work on the engine.

    Rated 5 out of 5 by from Chucked it in my Corsa My Corsa had been running a bit rough for a few weeks. Slow engine Performance and just did not feel like it wanted to get out of bed. Gave it a good seeing too down the A3 and still no joy. Chucked the bottle in with a full tank and has done the trick. Dont really know what is in it and to be hones i dont care. It just worked. Bit pricey but rather pay more for something if it works. Good stuff
