Most accurate way to work this out is reset your trip to 0 fill the tank from the red to full. Next time you fill up see how many miles you've done and how many litre it had taken you to fill the tank
For example =
18.46 litre 190 miles on the trip
(190 miles / 18.46 Litres ) x 4.54 (Litres in a gallon) = Your MPGĀ
For example =
18.46 litre 190 miles on the trip
(190 miles / 18.46 Litres ) x 4.54 (Litres in a gallon) = Your MPGĀ
