Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in kilometers or miles).
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 fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Calculation 1:
Multiply liters used by 100, then divide by total
kilometers traveled.
Calculation 2:
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 lower fuel economy.
Driving style — good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•
Smooth, moderate operation can yield up to 10% savings in fuel.
•
Steady speeds without stopping will usually give the best fuel
economy.
•
Idling for long periods of time (greater than one minute) may waste
fuel.
•
Anticipate stopping; slowing down may eliminate the need to stop.
•
Sudden or hard accelerations may reduce fuel economy.
•
Slow down gradually.
•
Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•
Revving the engine before turning it off may reduce fuel economy.
•
Using the air conditioner or defroster may reduce fuel economy.
