Car Log is an Android fuel log and car maintenance app. It records every fill-up and works out the consumption between full tanks, keeps the service log with reminders by date or odometer, lists the car's expenses, and reports what the car costs you per month, per year and per mile.
Most fuel log apps put the export of your own data behind a subscription and keep it on a server. Car Log has no account and no subscription; the PDF and CSV exports are free, and your Fuelio, Drivvo or Simply Auto history comes in with one CSV file. It handles petrol, diesel, flex, LPG, CNG, electric and plug-in hybrid cars, and two fuels in one car.
- Fill-ups and gas mileage — mpg, L/100 km or km/L, each average with its period. Fuel log
- Service reminders — by date or odometer, per vehicle. Maintenance log
- Costs — by month or year, cost per mile, charts. Cost report
- Your data out — CSV, PDF and full backup, free. Import and export
Ads pay for the app, and one purchase removes them. Nothing is tracked when no trip is running.

Guides
Calculate gas mileage
Two full tanks and the odometer are all you need. Here is the method, and the traps.
Cost per mile
All the costs of a period, divided by the miles the odometer shows for that period.
Oil change interval
Your owner's manual decides. The rest is remembering when.
Ethanol or gas
Ethanol is cheaper per litre but you burn more of it. The rule of thumb, and the exact break-even for your car.
Switch from Fuelio or Drivvo
Your history comes along: export one CSV file from the old app, import it into Car Log.
Know what your car really costs
Log the fill-ups and services, and let the app work out the mileage, the reminders and the cost per mile.
