You are right Colby. Apprarently its a delivery system with some sort of liquid cleaner. I don't know if it pressurizes the intake system or what.
I think I'll give the Trimaxxx a try. I know I have some piston slap, so there is for sure some carbon build up in my system.
I am concerned one or more lifters are a little sticky. I have more cold start noise than 6 months ago. I imagine that the only solutionif it isn't piston slap alone is oil with high levels of detergents or cleaner in the oil itself. Not too excited about that, though I know some have done it.

That seems goofy, how would carbon deposits make piston slap occur? The only way I could see is if it only built up on one half of the piston, thus causing it to be more unevenly balanced. But that is only a guess as to how it would be caused, and after repeating it to myself seems rathar unfeasable.

I'd try some thicker oil.
