Re: Stp?
When I rebuilt a 292 in 1977, my buddies were down on ever using it, as they considered that the additives just gunk up your engine and make cleaning it for rebuilding that much harder.
Until a few years ago, when I was concerned about the level of ZDDP in common motor oil, I started using STP for the zinc. When I found out Valvoline Racing had the right amounts of ZDDP, I went to VR1 SAE 30 exclusively.
