oil brand
I use and recommend BRAD PENN racing oil.
It's got enough ZDDP to suit me.
20-50 for drag racing.
Nitro 70 for blown alcohol pulling trucks.
This stuff is also so "clingy" its tough to clean off engine parts.

Hey David,
I finally took the time to read the article w/o being interrupted. I understand now. I like the viscosity of a straight weight oil such as 50 or 60; but with a really good additive for cold starts. On an older engine, it seems like a good comprise in Spring/Summer in my CJ7 w/ Mopar 360 (mildly built). I see good OP @ OT & idle, but I also have a little security in those oils when the temp is quickly fluctuating like Jeeps can do. The motor is broke in well & probably has pretty big bearing tolerances- oil pressure w/ 10/40 @ idle bugs me too much when I look at the gauge & see 8lbs... I guess it is part mental too.
