Fuel Filter

For fuel filter replacement, see your dealer or a qualified service

technician. Refer to scheduled maintenance information for the

appropriate intervals for changing the fuel filter.

if an authorized Motorcraft fuel filter is not used.

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 fill-ups or fuel gauge readings are

NOT accurate as a measure of fuel economy. We do not recommend

taking fuel economy measurements during the first 1,000 miles (1,600

km) of driving (engine break-in period). You will get a more accurate

measurement after 2,000 miles-3,000 miles (3,000 km–5,000 km).

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 the Refill capacities

section of this chapter.

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 fuel remaining in the fuel

tank after the fuel gauge indicates empty.

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.

For consistent results when filling the fuel tank:

• Turn the engine/ignition switch to the off position prior to refueling,

an error in the reading may result if the engine is left running.
