It only serves purpose to ensure the drivers are atleast using an acceptable oil and to pad their pockets with license fees.
The real point is that MC 5w30, synthetic blend or not, does not list any specs above or beyond any ordinary conventional on the market. Could it meet dexos1? I don't know, but it sure doesn't even make the claim. It's fair the Ford won't pay GM the fee. But, the Motorcraft spec doesn't require a blend, unless we just take it for granted that all conventional 5w30 options are the market are actually blends in the first place, and Motorcraft is saying they're a blend while Shell markets Pennzoil conventional as a conventional.
If Ford's blend is a step above ordinary conventional, they'd do well to show me. How about a dexos1 claim, if not a license? How about A1/B1? How about making a 0w30 instead of a 5w30?
