Your files stay on your device Mileage calculator (MPG and km/L) Enter a fill-up log or one refill-to-full trip and read your true fuel economy in km/L, L/100 km, US MPG, and UK MPG with cost per distance. Paste a fill-up log to read your true economy. A log only tells the truth between full tanks. Fuel added on a partial fill-up is still counted, but a span only starts and ends where you marked the tank full, because the leftover fuel in the tank is unknown anywhere else. The cost lines come from the price column at the pump, not from any live fuel price. If your car reports its own figure, compare it after a few tanks: onboard economy readouts tend to flatter.
