Vehicle Log – How Do I Track Fuel Mileage and Service?

Record the odometer, litres and total cost at each fill-up to track mileage and fuel price. Add service entries with cost and the next due date or odometer reading. Vehicle Log keeps these records offline and summarizes monthly spending, mileage, cost per kilometre and upcoming or overdue service.

Worked example

The previous fill-up was at 12,500 km and the next is at 12,900 km with 20 litres added for ₹2,000. Distance travelled is 400 km, so mileage is 20 km/L and fuel cost is ₹100/L.

How do I track fuel mileage and service?

Record the odometer, litres and total cost at each fill-up to track mileage and fuel price. Add service entries with cost and the next due date or odometer reading. Vehicle Log keeps these records offline and summarizes monthly spending, mileage, cost per kilometre and upcoming or overdue service.

How do I calculate fuel mileage from fill-ups?

Subtract the previous fill-up odometer from the current odometer, then divide the distance by litres filled. If the vehicle travelled 400 km and used 20 litres, the mileage is 20 km/L.

How do I calculate fuel cost per litre?

Divide the total fill-up cost by the litres added. A ₹2,000 fill-up of 20 litres costs ₹100 per litre.

How do I calculate vehicle cost per kilometre?

Divide the recorded vehicle spending by the distance travelled for the same period. If fuel and service cost ₹5,000 over 1,000 km, the running cost is ₹5 per kilometre.

How can I track when a vehicle service is due?

Save the next service date, next service odometer, or both. A service is due when the date arrives or the vehicle reaches the due odometer; it is overdue after either limit has passed.

What should I record in a vehicle fuel log?

Record the fill-up date, odometer reading, litres and total cost. Consecutive odometer readings let you calculate distance and mileage, while litres and cost show the price per litre.

Can I keep a vehicle log without internet?

Yes. Vehicle Log stores fuel and service records on the Android device and calculates summaries offline.
