Re: Synthetic Oil
My owners manual says to change the oil and filter when the DIC says to, or at least once a year. 3000 miles only if you accidentally reset the monitor. Next time, I'll probably change my oil with 25% life left, but that's just me.
If GM says you can trust the oil monitor, the dealer can't say different. They have to honor the GM written warranty, not the dealer's opinion.
