Filling the Fuel Tank
For consistent results when refueling:
•
Always switch the ignition off before
refueling. If you leave the engine
running, you will get an inaccurate
reading.
• Use the same fill rate each time you fill
the tank.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1,000 mi (1,600 km) of driving (this is
your engine ’s break-in period). A more
accurate measurement is obtained after
2,000 mi (3,200 km)
to 3,000 mi
(4,800 km). 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 fuel tank, record the amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. To calculate L/100 km (liters per 100 kilometers) fuel consumption, multiply
the liters used by 100, then divide by
kilometers traveled. To calculate MPG
(miles per gallon) fuel consumption,
divide miles traveled by gallons used.
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of your
vehicle's fuel economy under current
driving conditions. Conditions
•
Heavily loading your vehicle reduces
fuel economy.
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Adding certain accessories to your
vehicle may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures.
• Fuel economy may decrease when
driving short distances.
• You will get better fuel economy when
driving on flat terrain than when driving
on hilly terrain.
