He's an Amsoil guy, or I should say he was then. I'm not sure if he's still using it or not, but there are a lot of comparable oils I think are just as good.

That Schaefer oil I've read about and it sounds good. Never tried it but I wouldn't be afraid to.

Something dad's engine does with the 20-50 Z-rod, it has over 70 psi oil pressure while cruising but at a hot idle it's around 30-ish after a long highway jaunt. I see it as pretty normal. Thinner oil might bring both of those readings down a pinch to something some here might consider more normal, but I kind of like decent oil pressure at idle with hydraulic roller lifters and sometimes that requires a decent oil pump, so we've just left it as is. Some of that has to do with oil clearances too but for the most part, hot idle is what I pay most attention to.
