My change oil light just came on and I only have/had around 2500 miles on it. What's up with that? I know GM goes by engine revolutions and not miles, I know my Jeep doens't have that many revol's on it, and if they just set a milage, why the hell is it set to 2500 miles. Most cars, set to revolutions, go off somewhere between 4500-5500 miles, or around there. Anyway, I was very surprised to see this. Called the dealer/service, he was like, uh, I guess someone set it different. Who is someone?????????? Why isn't it standard. Things that make you go hmmmmmmm.
