What to write in a vehicle maintenance log
A maintenance log is a running list of everything done to one vehicle. It takes a minute per entry and saves guessing later. Each line should have:
- Date of the service
- Mileage on the odometer at the time
- Service performed, such as oil and filter change, tire rotation, brake pads
- Parts and fluids, with brand, grade or part number when you have it
- Done by, the shop name or "self"
- Cost, so you can see what the vehicle costs to keep
At the top, record the year, make, model, VIN and plate so the log always matches the right vehicle.
A filled example
| Date | Mileage | Service | Parts | Cost |
|---|---|---|---|---|
| 03/02/2026 | 58,100 | Oil and filter change | 5 qt 0W-20, oil filter | $64.00 |
| 03/02/2026 | 58,100 | Tire rotation | None | $25.00 |
| 07/18/2026 | 62,900 | Front brake pads | Ceramic pads | $210.00 |
These are sample numbers to show the format. Your costs and intervals will differ.
How to keep the log going
- Keep the printed log in the glove box with a pen, or bookmark this page on your phone.
- Write the entry the same day, while the receipt is in hand.
- Staple or file receipts in date order behind the log.
- Check the owner's manual schedule each time and note when the next service is due.
Common mistakes
- Skipping mileage. Most service intervals are in miles, so the date alone is not enough.
- Only logging big repairs. Small jobs like wiper blades and air filters add up and show steady care.
- One log for two cars. Keep one log per vehicle.
Before a road trip or a sale, run through the vehicle inspection checklist and keep it with this log.
