Haven't used the AMSOIL product, but used to use something similar from Ford, and Berrryman's. Was great for cleaning the carbon deposits that built up in the intake system. I'll look for a can of it next time I'm in the parts store. I have a 93 Burb with 200k miles so it could use it.

What does that cost, how much is needed?

[gmcjohnny]

we sell a can for 7.95 an if you can use the whole thing at once thats cool
