I would like to see some other input here, especially from Lubemaster, before I start sounding like I'm giving a sales pitch. Also, because Lube is legitimately "in the business" and not just some independent oil seller like me.

Although I have read some stories about excessive tappet wear and damage, I am not knowledgeable on the subject to the point that I would care to comment.

Regarding break-in oils...
Amsoil says that you can break in with their product with no adverse problems. In fact, Porsches, Covettes, and several others come from the factory with synthetic oil in them from day 1. However, many people point out that there is a difference between a factory new engine and an overhauled engine. It is my personal preference to break in an engine with standard mineral oil, then switch to a synthetic when I feel the rings have seated properly.
