Most modern cars need an oil change every 5,000 to 7,500 miles, and engines that run on full synthetic oil can often go 10,000 miles or more. Your owner's manual and the car's oil-life monitor have the final say. If you barely drive, don't wait for the miles: change it at least once a year.
The old rule of every 3,000 miles is out of date for most cars. AAA's oil change guide says it used to be standard, but most engines are now built for 5,000 to 7,500 miles between changes. AAA's first rule is the same as every automaker's: follow the maintenance schedule in your owner's manual.
Oil change intervals by oil type#
AAA gives these general ranges:
| Oil type |
Typical interval |
| Conventional |
About 5,000 miles |
| Synthetic blend |
About 6,000 miles |
| Full synthetic |
10,000 to 15,000 miles |
Use the oil your manual specifies, both the viscosity (like 0W-20) and any approval standard listed. Many newer engines require synthetic, in which case the cheaper conventional oil isn't an option. Synthetic costs more per change, but you change it less often.
Should you trust the oil-life monitor?#
Mostly, yes. Many newer cars have an oil-life monitor that estimates when the oil needs changing based on how and where you actually drive. If yours tells you to change it sooner than you expected, do it.
AAA notes that these monitors are helpful but not always accurate, so don't use one as a reason to go far past the maximum interval in your manual. And make sure the shop resets it after the change; otherwise it keeps counting down from the old oil.
What counts as severe driving?#
Many manuals have two schedules, normal and severe, and the severe one has shorter oil change intervals. AAA's examples of severe conditions include:
- Mostly short trips of 5 miles or less
- Sustained stop-and-go driving
Your manual may add towing, carrying heavy loads, dusty or unpaved roads, or extreme heat or cold. Short trips are the one that catches people out: the engine never fully warms up, so moisture and fuel don't burn off. A car that only ever does a 3-mile commute and the grocery run is a severe-service car even if it barely racks up miles.
Do you need an oil change if you don't drive much?#
Yes. Oil ages even when the car sits, and most manuals pair the mileage interval with a time limit. If you drive 3,000 miles a year, you'll hit the time limit long before the mileage one.
How late is too late? AAA says going a few miles or a few weeks past the interval isn't worth worrying about. If it's been more than a year, or well past the interval, get it done.
Check the oil level between changes#
An oil change schedule tells you when the oil is worn out, not whether there's enough of it. Some engines burn or leak a little oil between changes, and running low can do real damage.
Check the level once a month, following your manual. For a car with a dipstick, that usually means:
- Park on level ground and turn the engine off. Your manual will say whether to check it warm or cold and how long to wait.
- Pull the dipstick out, wipe it clean, push it all the way back in, then pull it out again.
- Read the level against the two marks. It should sit between them.
- If it's low, add a small amount of the specified oil, wait a minute, and recheck. Overfilling is a problem too.
Many newer cars don't have a dipstick and show the oil level on the dashboard instead. Topping up is not a substitute for an oil and filter change.
Oil pressure warning light vs. oil change reminder#
These are very different messages. An oil change reminder, usually a wrench symbol or a text message, means service is due soon. You can book it for next week.
The red oil can symbol is the oil pressure warning light, and it means stop. AAA describes it as the warning light with the greatest potential for serious mechanical damage, and advises that if it comes on and stays on, you pull off the road at the first safe opportunity, shut off the engine, and call for help. Don't drive to the nearest shop. Your owner's manual has the exact steps for your car.
Hybrids and electric cars#
Hybrids have a gasoline engine, so they need oil changes on the schedule in the manual, even if the engine spends a lot of time switched off.
Fully electric cars have no engine oil to change, but they still have tires, brakes, filters, and coolant to look after. The car maintenance schedule covers those.
Keep a record#
After each change, write down the date, mileage, and the oil used. Keep the receipt; it matters for warranty claims and when you sell the car. Michelin recommends rotating tires every 5,000 to 7,000 miles, so it's easy to rotate the tires at the same visit.
Set a ChoreLists.com reminder for the next change at whichever comes first, the mileage or the date. Low-mileage drivers especially need the date-based one, because the odometer won't remind them.
