GM warranty cover synthetic oil? Factory fill LS3
1st - Doesn't the LS3 use Mobil1 from the factory. My service advisor told me the car should use Dexos. Also I think Mobil1 is a dexos oil.
2nd - Does GM Easy-care cover synthetic oil changes? I have this coverage that will do scheduled maintenance of the car. But I'm not sure covers using synthetic oil. And my dealership says they may charge me for using it... I just feel like if I'm going to be charged extra for synthetic and the car comes with and recommends to use it, what good is that coverage?!?!
