First, after the Synpower rebate fiasco I'm no fan of Valvoline.
That said, picking on Valvoline products seems to be popular here, but where is the data to back it up?
I think it is now well demonstrated that nothing in VOAs correlates to how well oils perform as judged by UOAs.
People opine here about the "weak additive package" of Valvoline All Climate, but then Motorcraft oils are highly though of even though nothing which shows up in VOA backs it up. VOA results seem to be the basis for the claim about weak additive packages in Valvoline All Climate.
So, point me to the UOA results or other data which demonstrates the weakness of Valvoline All Climate as compared to other popular dino oils like Quaker State.
Based on everything I've seen on this site, there seems to be no correlation between VOA results and UOA results. The matter of correlating UOAs to actual engine mechanical wear is yet another kettle of fish, but the leap of logic which says that more wear metals showing up in UOAs means more metal wear inside the engine is at least plausible.
