That's great. However, it means nothing if you change you oil every 5 to 7K miles, which most people do. If you change it that often, the TBN can be 8, and your engine will be perfectly fine. You show me a motor head that is going to leave oil (of any kind) in an engine for 25K miles.

That is why I say any oil for 5K miles is just as good. If I were a fleet operator, I would consider doing a small portion of the fleet on the amsoil stuff and take notes at 150K miles and compare.
