I have the OnStar Diagnostics set up on my H2 and my wife's H3. Very nice system.
As for the oil change, I use the in dash meter too. When I go in and get one of those silly stickers on the window saying "Come in in Another 3,000 miles" I tear it off. As Fstop mentioned, I think it's very safe to trust the system. Why would it be there otherwise!? It obviously not helping the dealers any, and if you follow it and the engine siezes up, that's not really helping GM either. So let the computer control your life... </div></BLOCKQUOTE>
You are so right...the dealers screamed bloody murder when this system was released. Surprising to me (and many others), dealers performed a ton of oil changes and that has been cut down considerably.
