Until recently, I thought Amsoil only used ExxonMobil's PAO with Lubrizol additives. Does anyone know what base stocks Amsoil uses in there various oils? And additives? Amsoil doesn't give this information out according to them, but I thought someone might have an idea.

Buster - the old timer Amsoil guys might know, but it certainly isn't a thing they tell the grunt dealers such as myself. I suspect that they do get base oils from more than one supplier, but I have heard that most PAO's come from Exxon.
