unleaded fuel or can get only fuel with an
anti-knock index that is lower than your vehicle
needs, contact a district or owner relations office
before you leave the U.S. or Canada.

appropriate precautions with long hair.
*
[SV02000(BEF )01/95]

Cleaning the Engine
*
[SV05920(BEF )04/95]
A clean engine is more efficient because a
buildup of grease and dirt acts as an insulator,
keeping the engine warmer than usual.
*
[SV05940(BEF )05/95]
q
Extreme care must be used if a power washer
is used to clean the engine. The high pressure
fluid could penetrate sealed parts and
assemblies causing damage or malfunctions.
*
[SV05960(BEF )04/95]
q
In order to avoid possible cracking of the
engine block or fuel injection pump, do not
spray a hot engine or injection pump with
cold water.
*
[SV05980(BEF )04/95]
q
The alternator, distributor and air intake must
be covered. Covering these components will
help prevent water damage.
*
[SV06000(BEF )04/95]
q
Never wash or rinse the engine while it is
running. Water getting into the engine may
cause internal damage.

[SV06700( ALL)01/95]
Removing the fuel cap
*
[SV06750( ALL)01/95]
The proper instructions for removing the fuel
cap are as follows:
*
[SV06800( ALL)03/90]
q
Unscrew the fuel cap by exerting pressure on
the plastic lock bar and rotating the fuel cap
counterclockwise.
*
[SV06850( ALL)12/91]
q
Turn the fuel cap 1/2 to 3/4 of a turn until a
hissing sound is heard. Wait until the hissing
sound stops and then continue rotating
counterclockwise to remove the fuel cap.
*
[SV06900( ALL)03/93]
q
Make sure that you follow the above fuel cap
removal instructions and use caution. Such
caution will minimize the possibility of fuel
spraying during removal of the fuel cap.
*
[SV06950( ALL)03/91]
To replace and secure the fuel cap; place it in
position and rotate it clockwise until it clicks
(ratchets). Doing so will not damage or break
the fuel cap. The ratcheting mechanism allows
the fuel cap to be sealed without overtightening.
[SV06975( ALL)05/95]
If you lose the fuel cap, replace it with an
authorized Motorcraft or equivalent part.

hear a hissing sound, wait until it stops
before completely removing the cap.
*
[SV07060(BEF )11/89]
A venting fuel tank is not an abnormal
condition. It may be caused by:
*
[SV07061(BEF )03/90]
q
Too volatile a fuel for the weather conditions.
The service stations sometimes sell winter
grade fuel in the summer.
*
[SV07062(BEF )11/89]
q
Pulling a heavy load on hot days, or at high
altitudes.
*
[SV07063(BEF )11/89]

Octane recommendations
*
[SV08725( ALL)04/95]
Your vehicle is designed to use regular
unleaded fuel with an octane rating of 87.In
most cases, it is not necessary to use a fuel with
an octane rating higher than 87. At service
stations, the octane rating is displayed on a label
on the pumps.

[SV08900( ALL)05/95]
one inch art:0060001-C
Typical octane rating label
*
[SV09050( ALL)05/95]
In some parts of the country, ªregularº grade
fuels are sold with octane ratings of 86 or even
less, especially in high altitude areas. We
recommend that you do not use these fuels.
Always use a fuel with an octane rating of 87,
even if it is sold as a ªmidgradeº or ªpremium.º
*
[SV09200( ALL)05/95]
Do not be concerned if your vehicle sometimes
knocks lightly when you drive up a hill or when
you accelerate. However, if a fuel with the
recommended octane rating knocks heavily
under all driving conditions or knocks lightly
driving at cruising speed on level roads, see
your dealer or a qualified service technician.
Persistent, heavy knocking can damage the
engine.
*
[SV09435( ALL)05/95]
Fuel quality
*
[SV09450( ALL)05/95]
If you are experiencing starting, rough idle or
hesitation problems when the engine is cold, it
may be caused by fuel with low volatility. Try a
different brand of fuel. If the condition persists,
see your dealer or a qualified service technician.

Gasolines for clean air
*
[SV09900( ALL)05/95]
Fuels in certain areas of the country are required
to contain oxygenates to improve air quality.
Common oxygenates are ethanol or grain alcohol
(blended at no more than 10%), methanol or
wood alcohol (blended at no more than 5% with
cosolvents and additives), and MTBE or methyl
tertiary butyl ether (blended at no more than
15%).
[SV09950( ALL)04/95]
Reformulated gasoline is also required in certain
areas of the U.S. These fuels are designed to
further reduce the emissions from your vehicle.

Safety Information Relating to Automotive
Fuels
*
[SV10195( ALL)05/95]
RWARNING
Automotive fuels can cause serious injury
or death if misused or mishandled.
*
[SV10200( ALL)05/95]
Gasoline and other automotive fuels are
extremely flammable. Turn your vehicle off and
do not smoke while refueling your vehicle. Keep
sparks and other sources of ignition away from
fuels.
*
[SV10205( ALL)03/95]
Automotive fuels can be harmful or fatal if
swallowed. Further, gasoline may be blended
with methanol. Even small amounts of methanol
can cause blindness and possibly death when
swallowed. Therefore, never attempt to siphon
any fuel by mouth.
*
[SV10210( ALL)03/95]
If any fuel is swallowed, call a physician or
poison control center immediately.Do not delay
calling a physician merely because no adverse
effects are noticed at first; the toxic effects of a
gasoline-methanol blend, including blindness,
may not become apparent for many hours.If
gasoline is swallowed, do not induce vomiting.
If a gasoline-methanol blend is swallowed,
induce vomiting under the direction of a
physician or poison control center.
*
[SV10215( ALL)03/95]
Gasoline and gasoline-methanol blends may
contain small amounts of carcinogens, such as
benzene. Long-term exposure to unleaded
gasoline vapors has caused cancer in laboratory
animals. Further, excessive inhalation of fuel
vapors can cause headache, dizziness, nausea,

loss of coordination, and other symptoms which
could interfere with your ability to safely
operate your vehicle. To the extent possible,
avoid breathing vapors while refueling. If fuel
vapors are inhaled in excessive quantities, move
the victim to fresh air and seek medical
attention.
*
[SV10220( ALL)03/95]
Fuels can also be harmful if absorbed through
the skin. When refueling, be careful not to
splash fuel on yourself or your clothing. If fuel
is splashed on the skin, promptly remove
contaminated clothing and wash the skin
thoroughly with soap and water.
*
[SV10225( ALL)05/95]
Fuels can cause severe eye irritation and possibly
eye damage. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with large
amounts of water for 15 minutes, and seek
medical attention.
*
[SV10230( ALL)05/95]
You should be particularly careful if you are
taking the medication ªAntabuseº or other forms
of disulfiram for the treatment of alcoholism.
There is a possibility that breathing the vapors
of a gasoline-methanol blend, or skin contact
with such a blend, may cause the same kind of
adverse reaction as drinking an alcoholic
beverage. In sensitive individuals, serious
personal injury or sickness could result. Consult
a physician promptly if you experience an
adverse reaction.
