Re: Mileage between oil changes
My guess is you did not reset the oil change indicator, therefore the computer just went by your driving habits and mileage combo. Just a thought. But the manual does state 8,000 miles or 6 months for an oil change, whichever comes first, to keep your warranty valid. Many folks on here seem to miss that point. Do a search for oil change reset procedures or see instructions for the EVIC.
