Cleaning the Engine
*
[SV05665(ALL)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.
*
[SV05670(ALL)07/95]
n
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.
*
[SV05675(ALL)08/95]
n
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.
[SV05680(ALL)03/95]
n
The alternator, coils and air intake must be covered.
Covering these components will help prevent water damage.
*
[SV05685(ALL)04/95]
n
Never wash or rinse the engine while it is running. Water
getting into the engine may cause internal damage.

If you lose the fuel cap, replace it with an authorized Motorcraft
or equivalent part.

RWARNING
If you do not use the proper fuel cap, the pressure in the
fuel tank can damage the fuel system or cause it to work
improperly in a collision.
*
[SV07025(ALL)05/95]
NOTE: If you replace your fuel cap with an aftermarket fuel
filler cap, the customer warranty may be void for any
damage to the fuel tank and/or fuel system.
*
[SV07050(ALL)05/95]
RWARNING
If the fuel cap is venting vapor or if you hear a hissing
sound, wait until it stops before completely removing the
cap.
*
[SV07055(ALL)01/95]
You may occasionally hear and/or feel a slight thump occurring
one or two seconds after a gentle stop. This is normal and
generally occurs with the fuel tank 3/4 full. It is caused by the
wave action of the fuel within the tank.
*
[SV07060(ALL)11/89]
A venting fuel tank is not an abnormal condition. It may be
caused by:
[SV07061(ALL)07/95]
n
Too volatile a fuel for the weather conditions. The service
stations sometimes sell winter grade fuel in the spring.
*
[SV07062(ALL)11/89]
n
Pulling a heavy load on hot days, or at high altitudes.
*
[SV07063(ALL)11/89]
n
Extended periods of idling with the engine RPM increased
above the normal idle range.
*
[SV07064(ALL)11/89]
n
Parking vehicle in full sunlight for extended periods on
extremely hot days.

Choosing the Right Fuel
*
[SV07600(ALL)06/95]
Use only UNLEADED FUEL in your vehicle. Using leaded fuel
is prohibited by federal law. Your warranty may not apply if
your vehicle is damaged because you used the wrong fuel.
*
[SV07650(ALL)08/95]
Vehicle inspection programs may detect misfueling. Under these
circumstances, you may be required by law to make costly
repairs at your own expense.

[SV07700(ALL)05/95]
Octane Recommendations
*
[SV07750(ALL)06/95]
Your vehicle is designed to use regular 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 in a label on the pumps.
*
[SV07775(ALL)06/95]
one inch art:0060001-C
Typical octane rating label
*
[SV07800(ALL)07/95]
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
*
[SV07850(ALL)04/95]
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.

[SV07900(ALL)04/95]
In some parts of the country, ªpremiumº grade fuels are sold
with octane ratings of less than 91, especially in high altitude
areas. It is recommended that you use only those ªpremiumº
fuels with an octane rating of 91 or higher.
*
[SV07950(ALL)02/95]
Fuel Quality
*
[SV08000(ALL)06/95]
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.
*
[SV08050(ALL)09/95]
Using a high-quality fuel makes your vehicle more responsive
and maintains its good fuel economy and emissions by:
*
[SV08100(ALL)04/95]
n
minimizing deposits in fuel injectors, combustion chambers
and on intake valves.
*
[SV08150(ALL)08/95]
n
assuring quick starting and smooth warm-up.
*
[SV08200(ALL)08/95]
n
protecting the fuel system from vapor lock in very hot
weather, which causes the engine to hesitate or stall and
makes restarts difficult.
*
[SV08250(ALL)08/95]
n
protecting your fuel system from rusting.
*
[SV08300(ALL)08/95]
n
preventing the fuel lines from freezing.
*
[SV08350(ALL)06/95]
n
preventing the fuel system from ªgumming upº when your
vehicle is not used for long periods of time.
*
[SV08400(ALL)06/95]
It should not be necessary to add any aftermarket products to
your fuel tank if you continue to use a high-quality fuel.

Running Out of Fuel
*
[SV11400(ALL)05/95]
If your vehicle runs out of fuel, try to stop on level ground
away from traffic. Add at least two gallons (8 liters) of fuel to
start your vehicle again. If your vehicle is not on level ground,
you may need as much as five gallons (20 liters) of fuel to start
it.
*
[SV11500(ALL)07/95]
You may need to crank the engine several times before the fuel
system starts to pump fuel from the tank to the engine.

[SV11600(ALL)05/95]
Fuel Economy
*
[SV11700(ALL)07/95]
Fuel economy is an estimate of the efficiency of your vehicle
and can be calculated as Miles Per Gallon (MPG) or Liters Per
100 Kilometers (L/100K).
*
[SV11800(ALL)05/95]
To calculate fuel economy:
*
[SV11900(ALL)06/95]1.
Fill the tank completely and record the initial odometer
reading.
*
[SV12000(ALL)06/95]2.
Every time you buy fuel record the amount (in gallons or
liters) purchased.
*
[SV12200(ALL)07/95]3.
After at least three to five tankfuls, fill the fuel tank and
record the final odometer reading.
[SV12210(ALL)09/95]4.
Divide the total number of miles that you have driven by
the total number of gallons that your vehicle has used. In
metric, multiply the number of liters used by 100 and divide
the answer by the number of kilometers traveled. This will
give you the number of liters used per 100 km.

Comparisons With Environmental Protection Agency
(EPA) and Transport Canada (TC) Fuel Economy
Estimates
*
[SV12400(ALL)05/95]
EPA fuel economy figures are obtained from laboratory tests
under simulated road conditions and may not reflect the actual
conditions you experience or your style of driving. The EPA
fuel economy estimate is not a guarantee that you will achieve
the fuel economy shown.

Improving Fuel Economy
*
[SV12625(ALL)05/95]
Fuel economy is affected by a number of variables which can
reduce efficiency. You can improve fuel economy by
understanding these variables and minimizing their effect.
*
[SV12650(ALL)05/95]
The following decrease fuel economy:
*
[SV12675(ALL)05/95]
n
Lack of regular, scheduled maintenance
