These things will throw a trouble code for dirty oil?
We had an 02 Grand Am that had a change oil light that would come on based on calculations of throttle position, rpm's, and mileage.
Do the Aveos have this too? I bought mine used with 10,000 on it, and it had no manual. The oil was already dirty when I bought it, which pissed me off. I put a few hundred miles on it before seeing how dirty the oil was, and just recently changed it. So, I havent even put 2,000mi on the car since I bought it. I might not have even reached that point yet.
