March is Oil Change Month

How often should you change your oil?

Some manufacturers suggest that oil be changed every 7,500 miles or more, but that’s based on optimum operating conditions, and the manufacturers are the ones who get to sell you a new vehicle if your old one wears out prematurely. Although new vehicles can run longer on the same oil than older ones can, and improvements in motor oil have extended its efficiency over longer periods of time, to be on the safe side, you might want to change your oil every 5,000 miles or every six months, whichever comes first. If you’re a freeway driver who goes on a lot of long journeys at high speeds, you can probably extend the oil change interval, but on anything but the newest vehicles, don’t go longer than 5,000 miles between changes. And never, under any circumstances, go farther than the manufacturer’s recommended maximum interval between oil changes.
