Frequently asked questions

Can the real cost differ?

Yes. Actual mileage, traffic, fuel prices and idling change the real cost, so treat the result as a reference.

Does it work for diesel and gasoline?

Yes. Enter the price per liter of the fuel you use.

Does it fetch fuel prices automatically?

No. It uses the price you type in.

Can I use miles and gallons?

The fields expect kilometers, km/L and a price per liter, so convert miles and gallons first. The labels show Korean won (KRW), but the math works for any currency.
