Guys at work were telling me that is some of the best stuff you can get because it is strong stuff. It came into discussion when I was asking about their experiences with seafoam and how well it worked for them. They said that GM top engine cleaner was alot stronger than regular seafoam and would work alot better. Any experience or info about this stuff? One of the guys decided to get himself a can and I went ahead and bought one too. Just wanted to know?
