I'm still waiting for evidence of the "real lubrication benefits" that keep getting claimed for TGMO, even over other 0W20s (some of which have other manufacturer approvals).
Surely there's something in the sequence IV wear test (warm-up wear), or any of the other tests that are recognised by industry that would demonstrate this clear superiority, and "real lubrication benefits" to high VI...and they should be easy for one so well versed in this, the oil which we know more about than any other, to wheel out and demonstrate them to us.
But we never get proof, just statements regarding "self evident", and "obvious", and later an insult or three thrown in.
