Cleaner air

Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in the Choosing the Right
Fuel
section.

Running out of fuel

Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.

If you have run out of fuel:
• You may need to cycle the ignition from OFF to ON several times after

refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.

• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the

engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.

• The

indicator may come on. For more information on the

“service engine soon” indicator

, refer to Warning lights and

chimes in the Instrument Cluster chapter.

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 Maintenance
product specifications and 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.
