You say that they all meet the requirements just like i said but also state that's not the point. What is the point? Also funny story. A lot of people say it because the oil is made from Pennsylvania oil. The reason that is funny is because so is Brad Penn racing oil. Lol
Links references to pennzoil I just googled.

The point I was trying to make is that I want the absolute best oil, especially since they have similiar price points among their tier groups. I guess it really doesn't matter what brand you use in the grand scheme of things because a lot their addtives seem to work extremely similiar. But one of the brands must have at least one leg up on the competition and so far results are showing that it's Amsoil. Time will tell though.
