Oil Change Indicator System Question
What factors go into indicating an oil change is necessary? Never had a vehicle with a system like this I've always change my oil at 3k religiously. Now on this vehicle I had the oil changed at 1200 miles, thinking I was good for at least 3k miles but sure enough the light came on tonight to change the oil. If the dealer didnt reset the computer doesn't that mess up the intervals for the next change indicator message? Or does it need an oil change I'm at a little over 2500 miles now. Or did the dealer not change the oil like they claim they did any way to know that? Factory oil filters look the same or any other indicators?
