Are these chemicals good at what they do? I suppose the "proprietary additive" makes it hard to figure out.

Yes, but the experience of using both clearly made me choose regane. FYI, there are 2 types of STP fuel system cleaner too, I guess the old one is better, the new one is with label as lower price, that is the one which really smell kerosene when you open the bottle and really made the engine perform poorly if you use 1 bottle in small tank.
