How to use the calculator

  1. Last oil change. Enter the date and the odometer reading. Both are on the shop receipt or the old sticker.
  2. Interval. Pick the miles and the months from your owner’s manual, such as 10,000 miles or 12 months. Use “Other mileage” for any other number, or “No mileage limit” if your car uses only a time limit.
  3. Your pace. Enter the miles you drive a month, or today’s odometer. The calculator uses it to turn the mileage limit into a date.

The result shows the due odometer reading, the due date, which comes first, and the miles and days left. If you are past either limit, it says “Due now.”

How the next oil change is figured

  • Due by miles = odometer at the last change + interval miles
  • Due by date = date of the last change + interval months
  • Your pace = miles a month × 12 ÷ 365 per day, or (odometer today − odometer at the last change) ÷ days since the change
  • Date you reach the miles = today + miles left ÷ miles per day

Example: your last change was on September 12, 2026, at 42,000 miles. Your manual says 5,000 miles or 6 months, and you drive about 1,000 miles a month. The mileage limit is 47,000 miles, which you reach around February 11, 2027. The 6-month date is March 12, 2027. The mileage limit comes first, so the oil is due at 47,000 miles, around February 11.

Which interval to enter

Use the one in your owner’s manual or maintenance guide, for the way you drive. Examples from real schedules:

  • Toyota 2025 Corolla: when the reminder appears, and at least every 10,000 miles or 12 months; every 5,000 miles or 6 months if you drive mainly on dusty roads.
  • Chevrolet 2019 Equinox: when the oil life system says so, and at least once a year.
  • Honda 2022 Pilot: when the Maintenance Minder says so, and every year if no reminder appears.

If your car has an oil life monitor, it is the main guide. Use this calculator for the time limit and as a backup reminder, and enter the monitor’s yearly limit. The 3,000-mile option is there for manuals with that interval, often on a severe schedule, not as a general rule. See how often to change your oil and normal vs severe maintenance.

Oil change sticker: what it means

The sticker a shop puts on your windshield shows the next oil change by miles and by date, whichever comes first. The shop picks those numbers. They may be shorter than your manual calls for, so compare them with your schedule. If your manual allows more, you can follow the manual instead.

The calculator’s sticker shows the same things, based on your manual’s interval: the due miles, the due date, and the date and odometer of the last change. Print it, cut it out, and keep it in the glove box or on the inside of the windshield, where it doesn’t block your view.

Oil change every 3 months?

Only if your manual says so. The schedules above use 12 months for normal driving (Toyota, GM, Honda) and 6 months for mostly dusty roads (Toyota). If a sticker says 3 months, compare it with your manual. If you drive little, the time limit in your manual is the one to follow, because oil ages even when the car sits.

If you are past due

Check the oil level, add oil if it is low, and book the oil change as soon as you can. What carmakers say about going over, and what oil life percentages mean, is in how long you can go past an oil change. After the change, reset the reminder: see how to reset the oil light.

FAQ

When is my next oil change?

At the miles or the date your owner’s manual sets after your last change, whichever comes first, or when your oil life monitor says so. Enter your last change and interval above to get both.

How do I set an oil change reminder?

Work out the due date and miles above, then add the date to your phone’s calendar and keep the printed sticker in the car. If your car has an oil life monitor, reset it at each change so it reminds you too.

Should I follow the sticker or the oil life monitor?

Your car’s maker sets the schedule, so follow the oil life monitor or the owner’s manual. A shop sticker is a suggestion and may be earlier.

Does the calculator know my car’s interval?

No. You enter it from your owner’s manual. Intervals vary by make, model, year, engine, and how you drive.
