20w50 is too heavy. it is recommended when you need to take up slop in the build. It also requires more hp to push, and does not flow as quickly. You get a higher pressure at the gauge. Whoopeee, that doesn't mean you are protecting your engine better.
There is nothing wrong with synthetics. Some of our cars left the factory with it. Zero, zilch, nada. Some vettes in the 70s even left the factory with synthetics, with flat tappet cams and gen I engines.
And he can get to chugging. The only off the shelf oil at this time, 9/27/12, that has the "proper" ZDDP levels people look for is valvoline VR1. No Castrol, Mobil, Shell, Pennzoil, Wolf's Head, Quaker State, etc off the shelf oil has it anymore. So if you want zinc, it ain't in Pennzoil. Rotella used to, but not anymore. It was confirmed right from Shell.

i do want to run a 1540 but didnt know sheep stopped putting in zinc
