For regular, petroleum based oil, every 3,000 miles, for synthetic oil every 7,500 miles.
Happy safe driving!

In normal service areas, about 7K miles. Severe service about 5K.

Your vehicle's manufacturer will identify the schedule of maintenance for your vehicle. Most vehicles will require an oil change every 3-4,000 miles, however, you should consult your owner's manual, or check with the dealer for the specifics for your car/truck.

Rich, here in Minnesota, or colder norther climates it is recommended every 3,000 miles (conventional oil) as it is considered extreme conditions with the temperature fluctuations. A full synthetic oil can typically go about every 5,000 miles. I would refer to your owner's manual however, as the type of car and oil can cause a big variance. There are actually some cars that can go 10-20,000 miles between changes and some that will start burning oil if you too far beyond 3,000. If in doubt, find a local trusted shop and they can tell you based on your vehicle, oil type and driving conditions.
