Synthetic Oil

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.

Yep, I read the same.. What if you're on a 700 mile road trip and your DIC goes off at mile 200 and it's 1am in the morning?

If you haven't changed the oil for 7000+ miles and the DIC hasn't gone off yet, and you are about to go on a long road trip, get the oil changed before the trip. Plan ahead, it helps.

Yeah, it's tough being programmed all your driving life to do an oil change at 3,000 and then now 7,000. I guess that's my problem.

I'll stick w/ the OnStar recommendation and begin to use one of the Trip odometers to regulate.

Here's another question... do you tend to go through oil faster on long road trips or on 30-40 minute stop and go commutes?

Stop and go wears out the oil much faster than highway driving.
