When comparing oils, we always go off of UOA's and VOA's. It's been noted that a VOA will show every metallic element an oil contains. When you read a product description of an Amsoil product, they always refer to base stock blend. We know Amsoil and M1 are PAO based oils. So as of recently I've noticed Amsoil's additive package is on the weak side, however, it shows excellent numbers, which is all that matters. Could Amsoil be engineering their base stocks differently and relying more on them then other synthetics? This quote is from Tooslick awhile back:
quote:Now is this something that all PAO based oils contain? I bring this up bc an Amsoil tech told me that additive packages are the weak link in any oil and that Amsoil focuses on the base stock. Now this could mean, they just use a high quality PAO vs a Grp III. So when you think of Amsoil's additive package, which doesn't contain any Moly and hardly and boron or Calcium, there must be something else to their oils. Any ideas?

Amsoil uses oil soluble types of FM's .... Most of these compounds DON'T show up on oil analysis, as they are part of the basestock blend. These "might" include such compounds as organic fatty acids, amides, high molecular weight organic phosphorus and phosphoric acid esters.
