The American Automobile Manufacturers Association (AAMA) issued a
fuel specification to provide information on high quality fuels that
optimize the performance of your vehicle. We recommend the use of
fuels that meet the AAMA specification if they are available.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use a high-quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air quality, including
reformulated gasolines that contain oxygenates up to 10% ethanol or
15% MTBE.
Running out of fuel
Avoid running out fuel because this situation may have an adverse affect
on modern powertrain components.
If you have run out of fuel:
²You may need to crank the engine several times before the system
starts to pump fuel from the tank to the engine.
²Your ªService Engine Soonº light may come on. For more information

Cleaning the engine
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
²Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking the engine block or
other engine components.
²Never apply anything to the drive belt (including belt dressing).
²Cover the highlighted areas to prevent water damage when cleaning
the engine.
²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Cleaning plastic exterior parts
Use vinyl cleaner for routine cleaning. Clean with a tar remover if
necessary. Do not clean plastic parts with thinners, solvents or
petroleum-based cleaners.
Cleaning the exterior lamps
Wash with the same detergent as the exterior of your vehicle. Use glass
cleaner or tar remover if necessary.
To avoid scratching the lamps, do not use a dry paper towel, chemical
solvents or abrasive cleaners.
