I've always used an ample quantity of pre-lube for the bearings, cam lobes, seals, bores (no moly here), rings, etc, etc. But other than not using moly on the rings/bores/pistons, I'd just buy "stuff" called pre-lube (or, mix STP with regular oil, 50/50) and pour it on. So here's my questionS: 1. What is in this pre-lube??? And 2. Though most of it that I see is red in color, some I've seen is white. What is this white stuff? Thanks to any that can shed some light on this for me.
