I just had my oil changed. Dealer wouldn’t put in the 0w40...said it was an upgrade for corvettes only and not included in the free oil change. Said they could order it and install on
Next oil change if I paid for it. Is this the case everywhere? Are you guys getting the upgrade for free? I’m in Canada FYI.
Also, great post, but is there an official GM site somewhere wher I can go to show my dealer this posted Mobil 1 upgrade?

Thanks ��
