When Is My Oil Change Due?
Oil changes are the cheapest insurance for your engine — and overdue oil is one of the most common causes of avoidable wear. Here’s how to know when yours is due.
Typical intervals
- Synthetic oil: commonly every 7,500–10,000 miles, depending on the manufacturer.
- Conventional oil: commonly every 3,000–5,000 miles.
- Always follow your owner’s manual — it lists the correct interval and oil spec for your exact engine.
What shortens the interval
“Severe” driving — lots of short trips, towing, extreme heat or cold, or dusty roads — means changing oil more often. Many manuals list a separate, shorter severe-service schedule.
Oil-life monitors
Many modern cars calculate oil life from how you actually drive and show a percentage or a service light. These are more accurate than a fixed mileage number — service when it asks, and reset the monitor after each change.
Don’t just watch mileage
If you drive very little, change the oil at least once a year regardless of mileage — oil degrades with time and moisture, not just distance. Tracking your service dates makes this easy to stay ahead of.

How do I know when my oil change is due?
Follow your manual’s interval, watch your car’s oil-life monitor or service light if equipped, and track the date of your last change. Severe driving conditions mean changing it sooner.
