Cleaner Air; Running Out Of Fuel; Fuel Filter - Ford 1998 Mustang Owner's Manual

Maintenance and care
"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.
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:
You may need to crank the engine several times
before the system starts to pump fuel from the
tank to the engine.
Your "Service Engine Soon" light may come on.
For more information on the "Service Engine
Soon" light, refer to the Instrumentation chapter.

Fuel Filter

Your vehicle is equipped with a fuel filter that is
mounted on the underbody.
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the Scheduled
Maintenance Guide for the appropriate intervals for
changing the fuel filter.
