FUEL CONSUMPTION
Note: The amount of usable fuel in the
empty reserve varies and should not be
relied upon to increase driving range.
When refueling your vehicle after the
fuel gauge indicates empty, you might
not be able to refuel the full amount of
the advertised capacity of the fuel tank
due to the empty reserve still present
in the tank.
Empty reserve is the amount of fuel
remaining in the tank after the fuel
gauge indicates empty. Do not rely on
this fuel for driving. The usable
capacity of the fuel tank is the amount
of fuel that can be put into the tank
after the gauge indicates empty. The
advertised capacity is the total fuel
tank size – it is the combined usable
capacity plus the empty reserve.
Filling the Tank
For consistent results when filling the
fuel tank:
• Turn the ignition off before fueling;
an inaccurate reading results if the
engine is left running.
• Use the same fill rate
(low-medium-high) each time the
tank is filled.
• Allow no more than two automatic
click-offs when filling.
Results are most accurate when the
filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during
the first 1000 miles (1600 kilometers)
of driving (this is your engine’s
break-in period); a more accurate
measurement is obtained after 2000
miles - 3000 miles (3200 kilometers
- 4800 kilometers). Also, fuel
expense, frequency of fill ups or fuel
gauge readings are not accurate ways
to measure 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.
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. Calculate fuel economy by dividing
miles traveled by gallons used (For
Metric: Multiply liters used by 100,
then divide by kilometers traveled).
Keep a record for at least one month
and record the type of driving (city or
highway). This provides an accurate
estimate of the vehicle’s fuel economy
under current driving conditions.
Additionally, keeping records during
summer and winter show how
temperature impacts fuel economy.
In general, lower temperatures mean
lower fuel economy.
