That's the key. For more than you ever wanted to read about the subject, you can hunt down an oil thread from about 2007 on www.correctcraftfan.com. The horse was pretty well beat to death.

There was a later thread over here, too. From that, it was somewhat settled that the MC engines that would need to be worried about these things are any Fords and the pre-vortec TBI Chevies.
