yeah i've heard of it and almsot boughtit for my car. But 40.00 beans was alot for it. It si basically 3 seperate additives for your engine, fuel, and transmision right? From the information it sounds like a helluva product. It is just like a super lubricant that basically seals small cracks and cleans out carbs. Good point about where that stuff goes, I assume it gets broken down and jsut eventually disolved.
