A good jumping off point would be to look at your owner’s manual, which will probably supply a number between 5,000 and 7,500 miles. The manufacturer actually built the car, and as such should be viewed as the highest order when it comes to maintenance advice. Though, manufacturer recommendations are based on ideal driving conditions – driving short distances, never over the speed limit, that kind of thing – something the average driver would be hard-pressed to accomplish. As such, you’re better off using the “severe conditions” maintenance schedule, which will have you changing your oil roughly every 3,000 miles.
So, once you’ve uncovered the carmaker’s estimated oil change mileage, there are a few issues that need to be reviewed to adjust that estimate. Hard driving is a major wear and tear factor in determining the mileage amount for an oil change. If you’re driving in a lot in extreme conditions (both hot and cold), stop-and-go traffic, towing a trailer or hanging out on dusty roads, you must change your oil more frequently.
