So the long list of approvals makes it a better oil? I am following you, and dont disagree, but 0w40 does not carry dexos rating, and the kirkland does so?????Indeed, the proof is in the pudding, which in this case is an arms-long list of manufacturer approvals for M1 0W-40 that the product has passed the requirements for.
Without actual tear-down testing, that's the data we have access to. Trying to use UOA's is like asking Ms. Cleo.
I understand we are not talking gm, but we are also not talking mercedes either.
i dont disagree that 0w40 fs is not superior, fyi
