another thought,
I bet your oil cap says 0W-40 Mobil 1 Dexos 2 on it, just like mine does

I did all that....no go....this is just a forum with opinions. I even showed them the memo from this forum...no go. Even told them the 2019s will have the new oil....no go. My oil cap says dexos 5w40 but I did nut the 0w40 to install, which I will return now. When I showed them the LT4 memo, the response was the vette must have different calibration therefore requires a different oil. As long as GM CANADA WARRANTY says the recommended oil is 5w40, it will never change. Something has to be done higher up to make the change in the system.
