It's hard to square Doc Busa's theory with Yngve's. If oil loses it's viscosity as it ages, then it should be thinner and cause less internal friction...and new oil should cost you horsepower because it stays thicker. But as the Doc says, contaminants certainly should increase friction.
Maybe it's a saw off and the only real horsepower choice is 5 weight or synthetic, as others have suggested.
But if it turns out that old used oil makes more horsepower, I'll just drain the old Pinto out back and use that from now on.
I'm still confused.
Could be my natural state, of course.
I'll call my dyno tuner tomorrow.
