Switch from Fuelio, Drivvo or Simply Auto

Your history comes along: export one CSV file from the old app, import it into Car Log.

1. Export from the old app

Fuelio, Drivvo and Simply Auto can all export their log to a CSV file. Save it on the phone, or send it to yourself.

2. Import into Car Log

From the ⋮ menu of the Car screen, choose Import a CSV (Fuelio, Drivvo, Simply Auto, spreadsheet) and pick the file. Say the distance and volume units it uses, and which vehicle it belongs to if the file does not say. The preview shows what will come in.

What comes in

Fill-ups, partial ones and missed ones included, so the consumption stays right.
Services and expenses, with their reminders when the file has them.
Lines already in the log are skipped: importing twice does no harm.

And back out

Car Log exports to CSV in Fuelio's or Drivvo's own layout, for free. See Import and export.

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.

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.
