Aside from Assembly, which it is good for, What's wrong with STP? I've read somewhere it had a "sticky" quality that oil doesn't have. Also, I had a friend who said that engines that were lubed with STP would run longer with out oil than those on straight oil. (Not much longer, but longer) I admit, I never tested it out. But I used STP as an additive for years with
no ill effects. However. It doesn't work in Ford/Mazda 5 speed transmissions. If you have one, DON'T put STP in it. In the case of engines, did I waste my money adding it for all those years?
