What is the highest percent remaining when the dealer will do the included oil change?

Probably not. Road miles are the best and decrement the slowest, but as I said, even if it did zero out, there will be no harm done. Just get it changed when you get home. It's not that crucial.Like for example if I know I'm heading out to a long road trip (like Montreal~Miami) in the Cadillac but the oil life is at 30%... the oil life will naturally run out before I'm back, it is a 5000km round trip no?
GM cars and trucks NO longer require synthetic oil since the advent of dexos. GM dexos1 spec is a synthetic blend and GM free maintenance only uses AC Delco Synthetic Blend, something the dealers can get for peanuts. If you ask for synthetic oil they will charge you a hefty upgrade fee for it. I have a friend who did and they charged her $79.95 extra for Mobil 1.Not the synthetic oil that most cars require now a days to keep that computer that it's made for happy.
