Magical addictive
This product revitalised my 13-year-old car. It runs like a sewing machine. The postage was also incredibly fast. I am one happy customer who will always buy this product for my car

It works perfectly
After using this product, my car's engine management light turned off and black smoke stopped coming from the silencer. And I feel that my engine pickup has much improved.

Works like magic!
Absolutely wonderful product. Helpful for lowering emissions. Also makes my older golf run quieter and smoother. In my opinion better then 'similar' newer products.

All good
Seems to have made a difference to my Citroën relay after just one week. Engine seems a lot smother and acceleration seems better.

Good stuff
Recommended to use this by my mechanic as my diesel vehicle doesn't get used every day & without it he warned my fuel lines would get choked up with grime (but in much more technical terminology than that) Seems to be doing the trickRead full review

Good product works best in half a tank of fuel for me.
Works well to clean injectors. Suggest using in half a tank of fuel for best results
