Yeah, I'm currently reading it....very loooong. What I got so far is pick an oil that he has tested and has higher than 90,000psi for stock (mine so far), 105,000psi for built, change oil every 5000miles or yearly, and for cold starts take it gentle for the first 10 to 15 minutes. Kind of challenging the conventional wisdom of viscosity ratings and ZDDP levels.

I know I've found Valvoline VR-1 cheaper in the past, maybe it was on sale, but I think it was maybe $4 a quart? I can't seem to find any that cheap locally now?
