Amsoil Chemistry

What exactly is Amsoil using other then ZDDP to achieve good wear? When looking at their VOA's, all I ever see is loads of ZDDP. Hardly any Boron, no Moly and Calcium levels at or below Mobil 1's amount. Is the base oil contributing to protection? [Smile] Everyone has always talked about Amsoil's additive package. I say "What additive package?". The loads of ZDDP? I was told by Amsoil it's rather simplistic and by the looks of it, it is. They still get great wear from there oils so it is interesting how this happens. [ December 26, 2003, 06:51 PM: Message edited by: buster ]
I wouldnt say its any single component of the formulation such as the ZDDP that makes it good. I would say they just have a nicely balanced oil from the additive perspective.
Micro polishing is for the S2k chemistry. I have to be honest, it's sounds like a bunch of BS based on UOA's we've seen. S2k shows no better wear then the other Amsoil line.
