1998 Mercury Sable fuel

Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a one-eighth turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
If the ªService Engine Soon/Check Engine ª indicator
comes on and stays on when you start the engine,
the fuel filler cap may not be properly installed.
Turn off the engine, remove the fuel filler cap and
reinstall it being careful to align the cap properly.
If you must replace the fuel filler cap, replace
it with an authorized Motorcraft part. The
customer warranty may be void for any damage
to the fuel tank or fuel system if an authorized
Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If
the fuel filler cap is venting vapor or if you
hear a hissing sound, wait until it stops before
completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
If you do not use the proper fuel filler cap,
the pressure in the fuel tank can damage
the fuel system or cause it to work improperly in a
collision.
Maintenance and care

Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing (MMT).
Vehicles certified to meet California emission
standards (indicated on the underhood Vehicle
Emissions Control Information label) are designed to
operate on California reformulated gasolines. If
California reformulated gasoline is not available
when you refuel, your vehicle can be operated on
non-California fuels. However, even though your
engine will perform adequately on other gasolines,
the performance of the emission control devices and
systems may be adversely affected.
Repair of damage caused by using a fuel for which
your vehicle was not designed may not be covered
by your warranty.
Octane recommendations
Your vehicle is
designed to use
ªRegularº unleaded
gasoline with an
(R+M)/2 octane rating of 87. We do not recommend
the use of gasolines labeled as ªRegularº that are
sold with octane ratings of 86 or lower in high
altitude areas.
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 dealer or
a qualified service technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting, rough idle or
hesitation driveability problems during a cold start,
87(R+M)/2 METHOD
Maintenance and care

try a different brand of ªRegularº unleaded gasoline.
ªPremiumº 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.
Do not use gasolines containing methanol, which can
damage critical fuel system components. Damage
resulting from the use of methanol may not be
covered by your warranty.
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 on the ªService Engine
Soonº light, refer to theInstrumentationchapter.
Maintenance and care
157

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 ªService
Guideº for the appropriate intervals for changing the
fuel filter.
If you replace the fuel filter, replace it 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.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission
control components and a catalytic converter which
will enable your vehicle to comply with applicable
exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is
moving, especially at high speeds.
²Have the items listed in your ªService Guideº
performed according to the specified schedule.
The scheduled maintenance items listed in the
ªService Guideº are essential to the life and
performance of your vehicle and to its emissions
system.
If other than Ford, Motorcraft or Ford-authorized
parts are used for maintenance replacements or for
service of components affecting emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability.
Maintenance and care
158

Waxing your vehicle
Wax when water stops beading on the surface. This
could be every three or four months, depending on
operating conditions.
Use only carnauba or synthetic-based waxes. Use
cleaning fluid or alcohol with a clean cloth to remove
any bugs and tar before waxing vehicle. Use tar
remover to remove any tar spots.
Avoid getting wax on the windshield. If you have
wax applied at a commercial car wash, it is
recommended that you clean the wiper blades and
windshield as described inCleaning the wiper
blades and windshield.
Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with touch-up paint, repair foil or
aerosol paint spray from the Ford accessory line.
Observe the application instructions on the
products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your
vehicle. Do not use acid-based or alcohol-based
wheel cleaners, steel wool, fuel or strong detergents.
Never use abrasives that will damage the finish of
special wheel surfaces. Use a tar remover to remove
grease and tar.
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.
Maintenance and care
168

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.
Cleaning the wiper blades and windshield
If the wiper blades do not wipe properly, clean the
wiper blade rubber element with undiluted
windshield washer solution or a mild detergent. To
avoid damaging the blades, do not use fuel,
kerosene, paint thinner or other solvents.
If the wiper still does not wipe properly, this could
be caused by substances on the windshield such as
tree sap and some hot wax treatments used by
commercial car washes. Clean the outside of the
windshield with a non-abrasive cleanser such as the
non-abrasive Bon-Amitpowder. Rinse thoroughly
with clean water.Do notuse abrasive cleansers on
glass as they may cause scratches. The windshield is
clean if beads do not form when you rinse it with
water. The windshield and wiper blades should be
cleaned on a regular basis, and blades or rubber
elements replaced when worn.
Cleaning the instrument panel
Clean with a damp cloth, then dry with a dry cloth.
Avoid cleaner or polish that increases the gloss of
the upper portion of the instrument panel. The dull
finish in this area helps protect the driver from
undesirable windshield reflection.
