Was recomended to try this as my egr valve was sending my x type into limp mode. Purchased Formula Gold and filled tank and added this. The results were almost instant and i would highly recomend this product.

It made no difference at all to the running of my diesel. But that doesnt say it is a bad product it says the fault is probably not due to blocked jets etc. I will have to investigate further. Therefore I am not really qualified to say if this is a good product. Thank you.

This is the 1st time I have used this product and am impressed, I think I shall use it every 5ooomiles as it certainly seems to 'clean' the engines performance especially the torque which feels stronger the car pulling well and cleanly. A great product which we can all afford

Just passed MOT, tester struggled to get a reading or any smoke and it passed on fast pass! Levels were loads lower than last year and I follow the same routine prior to test, so can only put it down to this stuff. Worked great in a 2008 Saab 9-3 TTiD

This product is amazing, it worked within the first few miles of use. Cleared up the smoke I had coming out the back and I passed my MOT without any emission problems. engine runs so much more smoother now also.
