What to put in a car maintenance log
| Field | Why it matters |
|---|---|
| Service type | Shows what was done and what's due next |
| Date | Shows consistency and drives date-based reminders |
| Odometer reading | Drives mileage-based reminders and shows service intervals |
| Total cost | Feeds your cost per mile and yearly running costs |
| Shop and notes | Gives mechanics and buyers context |
| Receipt or record | Backs up the entry if a buyer or warranty claim asks |
How often each job is due depends on your vehicle, so use the schedule in your owner's manual for the intervals. A log doesn't replace professional inspections; it makes sure you know what has been done and what is coming up.
Keeping the log pays off twice: you catch overdue work early, and a documented history is one of the best ways to build buyer trust and support your asking price. See what to do before you sell your car and how much it costs to own a car per year.
