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.

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. Aftermarket products 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.

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.

• The

indicator may come on. For more information on the “Check

Engine” or 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
