ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km±5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill Capacities
section of theCapacities and specificationschapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of usable fuel remaining in the
fuel tank after the fuel gauge indicates empty.
The amount of 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.
For consistent results when filling the fuel tank:
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow three automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
