It seems that there's been some debate recently about the merits of Group III vs PAO oils. While there is no doubt that PAO is superior, ALL ELSE BEING EQUAL, is it possible that for over the counter oils (read Mobil 1) where cost needs to be controlled, the additive packages of OTC Group III's will be superior, on average? Not trying to start a flame war here. Just trying to understand the economics. PAO's cost more to produce so I'm wondering if Mobil tries to save on additives (to keep consumer prices manageable). On the other hand, since Castrol, Valvoline, Schaeffers, etc., don't bear the same costs as Mobil for the base oil, they can ramp up the additives. Is this sound thinking? I ask this because it seems many OTC Group III's perform as well as Mobil 1, as far as wear rates go. Having said that, I can imagine that non-OTC oils like Redline, Amsoil, etc. will be suprior than Group III's across the board since they are less constrained in their pricing.
