• Always use fuel with the recommended octane

rating.

• Use a known quality gasoline, preferably a

national brand.

• Use the same side of the same pump and have

the vehicle facing the same direction each time
you fill up.

• Have the vehicle loading and distribution the

same every time.

Your results will be most accurate if your filling
method is consistent.

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.
