Well, I'm getting a little nervous running my car until the change oil light comes on. It's been 7000 miles since my last change, and still no light. I don't want to damage the engine. Granted, it's been a lot of highway driving, which extends oil life for sure, but what do you think, is going 8000 miles okay? (They say in the manual when the light comes on you have 600 miles left, so by the time the light comes on and i have 600 left, I'm sure it'll be over 8000). I'm gonna talk to the service tech at the dealer and get his opinion. Wouldn't that suck if it turns out my oil life sensor is broke and it should've come on 4000 miles ago?
