FORD 1999 Taurus - Manual (Page 170)

Fuel quality
If you are experiencing starting, rough idle or
hesitation driveability problems during a cold start, try
a different brand of gasoline. “Premium” unleaded
gasoline should not be used (particularly in the United
States) if “Regular” unleaded gasoline is recommended
because it may cause these problems to become more
pronounced. If the problems persist, see your dealer or
a qualified service technician.
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 powertrain components.
If you have run out of fuel:
• You may need to crank the engine several times
after refueling before the system starts to pump
the fuel from the tank to the engine.
• Your “Service Engine Soon” indicator may come
on. For more information on the “Service Engine
Soon” indicator, refer to the Instrumentation
chapter.
Fuel Filter
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.
Replace the fuel filter with an authorized
Motorcraft part. The customer warranty may
be void for any damage to the fuel system if an
authorized Motorcraft fuel filter is not used.
