Cataclean Fuel Additive for Diesel 500ml (Twin Pack)

This product comes highly recommended, the following customer reviews have been supplied by Cataclean.

What an amazing product. My car failed it's MOT due to emissions. I was told it would be cheaper to scrap the vehicle rather than get it fixed. I bought this product used it and took my car for a good run . I then went to another garage for a second opinion & it passed that mot without any problems. Would definitely recommend buying this product.

You may be buying this because your MOT is coming up. Well this will definitely help you through the MOT, but more than that, it does actually change the way your engine runs. Used this for a couple of years now and each time I find my engine runs smoother afterwards and sound better too. Also passes MOT test with ease. I'd say it's good value because it actually works. Get it and see.

Purchased this after reading a lot of reviews and decided to use it. It certainly seems to have improved the performance in the engine,from ticking over smoothly to a feeling that the car is smoother through the gears. It went in for an M. O. T., a few days after adding it and the emissions test was no problem, and my car is 15 years old! I will definitely use it again.
