The typical recommended interval for oil changes has increased significantly from the old standard of every 3,000 miles. Modern vehicles generally require oil changes every 5,000 to 7,500 miles, depending on the car's age, type of oil used, and driving conditions
. If your car uses full synthetic oil, the interval can extend even further, often up to 10,000 to 15,000 miles
. Newer cars may have oil-life monitoring systems that adjust the oil change interval based on actual driving conditions and will alert you when an oil change is needed
. For older cars or those driven under severe conditions (such as frequent short trips, extreme temperatures, or towing), more frequent oil changes may be necessary, following the stricter schedule in the owner's manual
. Additionally, if you don't drive much, most manufacturers recommend changing the oil at least once a year to prevent oil degradation
Summary:
- Older guideline: every 3,000 miles
- Modern conventional oil: every 5,000 to 7,500 miles
- Full synthetic oil: every 7,500 to 15,000 miles
- Oil-life monitoring system: varies, based on driving conditions
- Time-based change if low mileage: at least once per year
Always consult your vehicle’s owner’s manual for the most accurate recommendations specific to your car
