I have a 2005 Chevy Classic (Malibu), The oil change was due on June 10th. I JUST passed the mileage last week however (3,000 miles). I checked and the oil isn't low. I don't redline it ever, I just use it for occasionally driving around town. Most of the 3000 miles came in early summer when I would drive to the beach. Since then I drive it every few days, and then only for a couple miles per whack. Should I get the oil changed soon anyway?
