Frequently asked questions
How do I calculate a trip's fuel cost?
Distance ÷ efficiency = fuel used; × price per unit = cost. Works for MPG or L/100km.
How do I split fuel with passengers?
Divide the total cost by the number of people. Enter passengers above for cost per person.
What's a good fuel efficiency?
Higher MPG (or lower L/100km) means better efficiency and lower cost per mile/km.
