2000 Mercury Mystique engine

Maintenance and care
198Choosing the right fuel
Use only UNLEADED FUEL. The
use of leaded fuel is prohibited by
law and could damage your vehicle.
The damage may not be covered by
your warranty.
Your vehicle was not designed to
use fuel containing manganese-
based additives such as MMT.
Additionally, vehicles certified to
California emission standards
(indicated on the underhood
Vehicle Emission 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 a fuel
that your vehicle was not designed
for may not be covered by your
warranty.

Maintenance and care
199 Octane recommendations
Your vehicle is designed to use
regular gasoline with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
“regular” in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your vehicle
sometimes knocks lightly. However,
if it knocks heavily under most
driving conditions on the
recommended octane, see your
dealer or a qualified service
technician to prevent any engine
damage.

Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, see your dealer
or qualified service technician.
The American Automobile
Manufacturers Association
(AAMA) issued a gasoline
specification to provide information
on high quality fuels that optimize
the performance of your vehicle.
We recommend the use of gasolines
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.

Maintenance and care
200Fuel filler cap
If the check engineindicator
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.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines that contain
oxygenates such as a maximum of
10% ethanol or 15% MTBE. There
should be no more than 5%
methanol with cosolvents and
additives to protect the fuel
system.

Maintenance and care
203 Watch for fluid leaks, strange
odors, smoke, loss of oil pressure,
engine overheating, illumination of
the charging systemwarning light
or the check enginewarning light.
These events could indicate that
the emission control system is not
working properly.
Exhaust leaks may result in
entry of harmful and
potentially lethal fumes into the
passenger compartment.

Do not park, idle or drive
your vehicle in dry grass or
other dry ground cover. The
emission system heats up the
engine compartment and exhaust
system, which can start a fire.

Maintenance and care
204
Do not make any unauthorized
changes to your vehicle or engine.
By law, vehicle owners and anyone
who manufactures, repairs,
services, sells, leases, trades
vehicles, or supervises a fleet of
vehicles are not permitted to
intentionally remove an emission
control device or prevent it from
working. Information about your
vehicle's emission system is on the
Vehicle Emission Control
Information Decal located under
the hood. This decal identifies
engine displacement and gives
some tune up specifications.
Please consult your “Warranty
Guide“ for complete emission
warranty information.
Readiness for
inspection/maintenance (I/M)
testing
In some localities, it may be a legal
requirement to pass an I/M test of
the on-board diagnostic (OBD-II)
system. If your check enginelight
is on, refer to the description in the
Instrument Cluster Lights and
Chimessection of the
Instrumentation chapter. Your
vehicle may not pass the I/M test
with the check engine light on.

Maintenance and care
205 If the vehicle’s powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a “not ready for I/M test“
condition. To ready the OBD-II
system for I/M testing, a minimum
of 30 minutes of city and highway
driving is necessary as described
below:
• First, at least 10 minutes of
driving on an expressway or
highway.
• Next, at least 20 minutes of
driving in stop and go, city-type
traffic with at least four idle
periods.
Allow the vehicle to sit for at least
eight hours without starting the
engine. Then, start the engine and
complete the above driving cycle.
The engine must warm up to its
normal operating temperature.
Once started, do not turn off the
engine until the above driving cycle
is complete.

Maintenance and care
219 Cleaning the engine
Engines are more efficient when
they are clean because grease and
dirt buildup act as insulators and
keep the engine warmer than
normal. Follow these guidelines to
clean your engine:
• Take care when using a power
washer to clean the engine. The
high pressure fluid could penetrate
the sealed parts and cause damage.
• Do not spray with cold water, to
avoid cracking the engine block.
• Cover the alternator to prevent
water damage when cleaning the
engine.
• Never wash or rinse the engine
while it is running; water in the
running engine may cause internal
damage.

Maintenance and care
221 Cleaning the interior fabric
Remove dust and loose dirt with a
whisk broom or a vacuum cleaner.
Remove fresh spots immediately.
Follow the directions that come
with the cleaner.

Clean the instrument panel with a
damp cloth, then dry with a dry
cloth.
Any cleaner or polish that
increases the gloss of the upper
portion of the instrument panel
should be avoided. The dull finish
in this area is to help protect the
driver from undesirable windshield
reflection.
Cleaning leather seats
(if equipped)
For routine cleaning, wipe the
surface with a soft, damp cloth. For
more thorough cleaning, wipe the
surface with a leather and vinyl
cleaner or a mild soap.
Ford recommends using the
Deluxe Leather Care Kit
F8AZ-196253-AA, which is
available from your Ford dealer.
This mild cleaner and special pad
cleans the leather and maintains its
natural beauty. Follow the
instructions on the cleaner label.
Regular cleaning of your leather
upholstery helps maintain its
resiliency and color.
