If I'm not mistaken, yes on Techron, douches out the fuel system. I always thought of STP as the oil treatment to provide additional lubrication and clean deposits in the crankcase.

Who knows. People still swear that Marvel Mystery Oil is great for the fuel and lubrication systems. You can put it in the fuel tank and the crankcase. They might be right.
