Calculating fuel economy
1. Fill the fuel tank completely and
record the initial odometer reading.
2. Each time you fill the tank,
record the amount of fuel added (in
liters or gallons).
3. After at least three to five tank
fillĆups, fill the fuel tank and record
the current kilometer (mileage)
reading.
4. Follow one of the simple
calculations in order to determine
fuel economy:
Multiply liters used by 100,
then divide by total kilometers
traveled.
Divide total miles traveled by
total gallons used.
Keep a record for at least one
month and record the type of
driving (city or highway). This will
provide an accurate estimate of the
vehicle's fuel economy under
current driving conditions.
Additionally, keeping records
during summer and winter will
show how temperature impacts fuel
economy. In general, lower
temperatures give a deterioration
in fuel economy.
