Gas mileage becomes useful when every fill-up follows the same format. A consistent tracker helps reveal driving changes, maintenance issues, and fuel cost trends.
Job to be done
Keep a fill-up history that shows fuel economy trends instead of one-off estimates.
Use this fill-up format in a spreadsheet or record it directly in Vehtraq.
| Date | Odometer | Fuel added | Full tank | Fuel type | Station |
|---|---|---|---|---|---|
| 2026-01-05 | 31,240 mi | 12.4 gal | Yes | Regular | Neighborhood station |
| 2026-01-18 | 31,628 mi | 11.9 gal | Yes | Regular | Highway station |
| 2026-02-02 | 32,004 mi | 12.1 gal | Yes | Regular | Neighborhood station |
For the cleanest mileage trend, compare fill-ups where the tank was filled to the same level.
Vehtraq turns one-off worksheets into vehicle records you can filter, review, and export. Fuel logs, service history, reminders, receipts, and costs stay attached to the vehicle they belong to.

Fuel economy can change for normal reasons, but sudden movement is worth investigating.
Vehtraq keeps gas mileage connected to vehicle records instead of burying it in notes or receipts.
