It is interesting that so many worry about a little lifter noise and not about spinning a bearing.

Sure the argument can be had that it is possible for aeration to decrease lift a few thousandths at idle, I say if a couple of hp at idle is worth the risk then have at it. Its not worth the risk to me as when RPMs go up the oil level in the pan decreases and oil pressure increases therefore you likely don't have any of the same aeration issues above idle anyway.
The point is, the OEM purposely overfill them because the masses don't care to trouble themselves with occasionally checking their oil. So, "full" on the dipstick is technically overfull. "Add" is just right on these engines.

I respect what you're saying, but really that was my point all along.
