Also, no Schaeffer oil is SN

I get so tired of these unethical companies that obfuscate on their data sheets. This is a particularly egregious example.
Its an ethics problem. Like Amsoil, I "feel" their oils may be about as good as they say. Yet without a genuine cert process in place, it comes down to trust. Personally, I often give Amsoil a pass, and if there are honest adults in charge at Schaeffer, then maybe we should just say their Penetro and high moly formulas are plenty good. I don't know.
Well, if it's any comfort, PQIA has tested Schaeffer and found it to
meet API SN performance requirements.
The lack of the official certification could be due to cost, or maybe one of their additives isn't considered kosher for the tests? They are, as far as I know, the only blender who uses antimony.
Personally I think the oil is fine, but it's not something I'm terribly interested in using myself given as there are plenty of other suitable oils for much less money.
