How we worked it out

Updated as you change the numbers.

  1. Fuel = distance ÷ miles per gallon (or distance × L/100 km ÷ 100). Cost = fuel × price.

Method and assumptions

Fuel used is the distance divided by fuel economy. Real-world economy varies with speed, load, weather and terrain; highway driving is usually better than the combined rating.

Questions
