Re: 15,000 mile oil change...
Wow, lots of stuff on this if you Google it. Here's a blurb from GM website:
What is the GM Oil Life System?
The GM Oil Life System is a computer based software algorithm that determines when to change oil based on engine operating conditions. There is no actual oil condition sensor. Rather, the computer continuously monitors engine-operating conditions to determine when to change oil.
I don't really know what it means, but my point was that it isn't just an odometer monitoring thing (like my wife's T&C van has).
