Originally posted by Dick in Falls Church: Having dealt with the folks at AMSOIL for over 25 years, I suspect that they would use moly if they though it would make their oil any better---
quote:True, it doesn't. I think what Terry says is very true for a lot of there oils. While it is a well built oil, they don't hold up like they use to. I never really thought Amsoil had bad wear numbers. In fact, I think they are generally a bit better then M1. My biggest complaint with there oil is the TBN depletion and out of grade viscosity. Moly wouldn't help this, as far as I know. It seems Boron and Moly though are the way to go these days. [ May 21, 2003, 08:19 PM: Message edited by: buster ]
