What does your car really cost to run? Most drivers only ever see the number on the pump. The fill-up you forgot, the insurance month, the surprise repair — without a record, the real cost per kilometre stays invisible, and there is no way to tell whether a new commute, tyre set, or driving style actually changed anything.
Fuel Log answers that question with data you own. Record a fill-up in seconds — date, odometer, amount, price, full or partial — and the app turns your history into real fuel economy and running costs: MPG, km/L, L/100km, monthly spend, lifetime totals.
