Do not be concerned if your engine sometimes knocks lightly. However, if

it knocks heavily under most driving conditions while you are using fuel

with the recommended octane rating, see your authorized dealer to

prevent any engine damage.

Fuel quality

If you are experiencing starting, rough idle or hesitation driveability

problems, try a different brand of unleaded gasoline. “Premium”

unleaded gasoline is not recommended for vehicles designed to use

“Regular” unleaded gasoline because it may cause these problems to

become more pronounced. If the problems persist, see your authorized

dealer.

Do not add aftermarket fuel additive products to your fuel tank. It

should not be necessary to add any aftermarket products to your fuel

tank if you continue to use high quality fuel of the recommended octane

rating. These products have not been approved for your engine and

could cause damage to the fuel system. Repairs to correct the effects of

using an aftermarket product in your fuel may not be covered by your

warranty.

Many of the world’s automakers approved the World-Wide Fuel Charter

that recommends gasoline specifications to provide improved

performance and emission control system protection for your vehicle.

Gasolines that meet the World-Wide Fuel Charter should be used when

available. Ask your fuel supplier about gasolines that meet the

World-Wide Fuel Charter.

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.
