OPTIONAL PREMIUM
Fuellin Premium removes ads and unlocks custom-period comparisons, cross-vehicle comparisons and detailed PDF reports. Fuel logging, basic statistics, CSV export and local backups remain available on the free plan.
Mileage and cost results are estimates based on the information you enter. Full-to-full mileage requires suitable full-tank endpoints and complete refill history.
