Fuel log
A fuel log that works out your real MPG
Log each fill-up with the odometer and the gallons. Milebook calculates miles per gallon between full tanks, warns you when it starts dropping, and keeps every receipt in one place.
MPG done the accurate way
Milebook uses the full-tank method: the distance between two full fill-ups divided by all the fuel you added in between, partial fills included. It's how mechanics check fuel economy without a sensor.
Know when something's off
When a tank comes in noticeably worse than your average, Milebook flags it. A sudden drop is often the first sign of low tire pressure, a dragging brake or a sensor problem.
Price trend and cheapest stations
Every fill-up records the price per gallon, so you can see what you've paid over time and which stations on your route are cheapest for you.
Gallons or liters, regular or diesel
Pick miles and gallons or kilometers and liters. Log regular, midgrade, premium, diesel or E85, and snap the receipt if you want to keep it.

Is the fuel log free?
Yes. The Free plan covers 2 vehicles with unlimited fill-ups, MPG, reports and CSV export, with no ads.
What if I don't fill the tank all the way?
Untick “filled the tank” for a partial fill. Milebook adds that fuel to the next full-tank calculation, so your MPG stays accurate.
Do I need to download an app?
No. Milebook runs in your phone's browser. Add it to your Home Screen and it opens like an app.
