If many think that a group III with a very good additive package such as Schaeffer's can perform as well as fully synthetic oil, why don't other companies such as Mobil start paying more attention to the additive package then the base oil? From what I've read on here, it sounds like the additive package is more important then the base oil. We see Schaeffer's performing as well or better then Mobil1 at times. You would think that it would be a cost cutting measure. How significant is the base oil if this is what some European oils are doing? Mobil seems to stress the significance of using a PAO.
