YOUR INTERVAL. YOUR SERVICE RECORD.

Oil change mileage calculator

Find your next service mileage and the distance remaining. Add a calendar limit if your own service plan includes one.

No account or installation. Your mileage and dates stay in this browser.

Your service numbers

Enter the interval from your own vehicle manual or service plan. No recommended interval is assumed.

All three mileage fields use this unit. Changing units does not convert your numbers. Use whole miles.

Optional calendar limit

Enter both fields to add a date threshold, or leave both empty.

BASED ON YOUR OWN INTERVAL

Your next service

Enter your records and choose Calculate next service to see your distance and optional date limits.

A reminder from your records

Start with the last service

If your last oil change was at 42,000 miles and you choose a 5,000-mile interval, the next threshold is 47,000 miles. At a current 45,600 miles, 1,400 miles remain. These are illustrative values, not a recommended interval.

Due means the limit is reached

At 47,000 in that example, the mileage limit is due exactly. At 48,000, it is 1,000 miles overdue. Negative remaining distance is shown honestly rather than reset to zero.

Months are calendar months

August 31, 2026 plus six calendar months is February 28, 2027. In a leap year, February can end on the 29th. Month-end dates are clamped to the final valid day.

Distance and date are different limits

Use the interval specified for your vehicle or chosen service plan. The calculator adds your numbers; it does not decide a manufacturer-approved interval. Without a driving-rate assumption, a mileage threshold cannot tell you the date you will reach it.

Can I use kilometres?

Yes. Choose kilometres and enter every mileage value in kilometres. Switching the label does not convert existing numbers.

Does this save a vehicle or set an alert?

No. This browser tool calculates one reminder summary. Your entries are not saved, sent to the mobile app or used to monitor your odometer.

Keep the history behind the next reminder.

Use Maintenance to retain vehicles, service history, mileage, costs and reminders. Enter your records in the app to keep them there; this calculator does not transfer them automatically.
