From the "Amsoil - Strategic Direction" thread Amsoil - Straegic Direction
And this is a problem in my view with the industry in terms of content vs advertising, because there are no guidelines wrt definitions for Conventional, Blend (or semi-synthetic, partial synthetic), Synthetic, or Full Synthetic. Today, a full synthetic often means that the oil could be a mix of Group III, IV, and V base oils in various proportions, thanks to the ignorant BBC decision. In my view, there should only be three categories of base oil content declarations as follows, so here is my "self-policing" declarations/definitions for Base Oil content for the industry for our future base Oils: Full Synthetic - Base oils would contain: Majority Group IV PAO's and Group V esters; or Group IV PAO's with Group V AN's and or Group V esters; or Group IV PAO's with Group V Ionic Liquids and or Group V esters; or Group IV PAO's with Group V OSP's and or Group V esters; or Group IV PAO's with Group V specialty Polymers and or Group V esters; or any combination thereof of Group IV/Group V base oil combinations that would fall into a strict definition of chemically synthesized base oils of Group IV or Group V, with an appropriate additive package. The only Group I or II base oils allowed would be those used as additive carriers, with an ("Exclusive of") phrase. In other words, the content/Liter would be: Total Content/Liter - %Additive Content = %Synthetic Base Oil Content as defined above. BLEND - Any combination thereof of Group II or Group III or Group IV or Group V base oils with a minimum 10% content of Group IV and or Group V base oils (as defined above), with an appropriate additive package. Conventional Mineral Oils - Any combination thereof of Group I, Group II or Group III mineral oils with an appropriate additive package. This would still allow the formulator or blender plenty of latitude in selecting base stocks and the Marketing department can still go ga-ga. I feel that if we don't self-police ourselves, some "Over-Zealous, Over-Regulation Mentality" type will come along and do it for us.
