Fuel quality
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use a high-quality fuel.
Unleaded Gasoline engines
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of “Regular” unleaded
gasoline. “Premium” unleaded gasoline is not recommended (particularly
in the United States) because it may cause these problems to become
more pronounced. If the problems persist, see your dealer or a qualified
service technician.
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.
FFV engine
Your FFV will operate well on ordinary “Regular” unleaded gasoline, but
only the highest quality fuel ethanol will provide the same level of
protection and performance.
If you are experiencing a rough or rolling idle after start-up with the
outside temperature above 27° C (80° F), the idle should improve within
10 to 30 seconds. If the problems persist below this temperature, see
your dealer or a qualified service technician.
To assist fuel ethanol providers in meeting high fuel quality standards,
the AAMA has published guidelines which prescribe “Ethanol Fuel
Compatible” dispensing station equipment. To ensure proper operation of
your FFV on fuel ethanol, refuel at stations certified by the AAMA.
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.
