I'm wondering what exactly triggers the Change Oil Soon light on a Saturn LS2 2000. Is it on a timer or milage linked or does it actually have a sensor that checks the oil quality....
The reason I ask is that mine is coming on when I start my car and goes off after about a minute. My oil is only about 1000 miles old, the level is fine, and it looks pretty good on the stick....
Is it possibly linked the my Service Engine Soon light that is perpetually on?
The car has 47000 miles.
Thanks,
Ken
