I don't know man, I agree with this about LA motors.
I'll spare ya the red X, but I think newer motors with better tolerances and thinner rings should run what they were designed to run.
I run the Full Synthetic 5-30 Castrol Edge Titanium for $17.39 plus tax for the 5 quart jug.
Specs are part way down the page.
