ivymike, good one, if you don't want to open your mind and try a proven product then go to some other topic, don't post here.

I used to think the same way, but luckily decided to try per Terry Dyson's analysis. When an engine has carbon build up and is run with a quality oil and a synthetic and nothing works to clean it (although Saabjohan thinks the oils today have enough cleaners in them) and then lube control ad fuel power are used and the carbon is cleaned away.

Not sure what that means to you, but what it means to me is that IT WORKS!
