Do not be concerned if your vehicle sometimes
knocks lightly. However, if it knocks heavily
under most driving conditions on the
recommended octane rating fuel, see your dealer
or a qualified service technician to prevent any
engine damage.
[SV09455( T)02/95]
SHO 3.4L engine
[SV09460( T)02/95]
The SHO 3.4L engine has been designed to
operate using premium unleaded fuel with an
octane rating of 91 or higher. Regular unleaded
fuel with an octane rating of 87 may be used if
necessary. For optimum performance and
driveability, it is recommended that you use
premium unleaded fuel.
[SV09470( T)12/95]
In some high altitude areas, ªpremiumº fuels are
sold with octane ratings of less than 91. It is
recommended that you use only those
ªpremiumº fuels with an octane rating of 91 or
higher.

Fuel quality
[SV09601(ALL)12/95]
Ford approves the use of gasolines, including
those reformulated, that contain oxygenates such
as ethanol (10% maximum) and MTBE (15%
maximum). If methanol is used, the gasoline
should contain no more than 5% with
cosolvents.
[SV09701(ALL)12/95]
If you are experiencing starting, rough idle or
hesitation problems, try a different brand of fuel.
If the condition persists, see your dealer or a
qualified service technician.
*
[SV09800(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.

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.

If you are taking the medication ªAntabuseº or
other forms of disulfiram for the treatment of
alcoholism, vapor or skin contact with a
gasoline-methanol 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.
[SV10250(ALL)05/95]
Fuel line service
[SV10270(ALL)11/94]
Fuel injection systems operate with pressurized
fuel. The fuel lines are under pressure even
when the engine is off. This system should be
serviced by an authorized dealer using only
Ford approved parts. Using other materials may
be hazardous or allow hydrocarbon emissions
above the legal levels set by the Federal
Government.

Running Out of Fuel
[SV11500(ALL)05/91]
If your vehicle runs out of fuel, try to stop on
level ground away from traffic. Add at least one
gallon (four 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.
*
[SV11550(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.
*
[SV11575(ALL)08/95]
If the engine does not start, check the fuel pump
shut-off switch and reset as required. SeeFuel

Fuel Economy
*
[SV13510(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).
*
[SV13515(ALL)05/95]
To calculate fuel economy:
*
[SV13521(ALL)06/95]
1. Fill the tank completely and record the
initial odometer reading.
*
[SV13526(ALL)06/95]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
[SV13530(ALL)09/95]
Keep a record for at least a month. This will
give you a more accurate estimate than
figuring the fuel economy based on only one
or two readings.
*
[SV13535(ALL)07/95]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.
*
[SV13537(ALL)10/95]
4. Use these equations to calculate your fuel
economy:
*

English: MPG = (total miles driven)
v(gallons used)

Comparisons With Environmental
Protection Agency (EPA) and Transport

[SV13545(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
*
[SV13561(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.

Checking and Adding Engine Oil
*
[SV13800(ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.

[SV13900(ALL)04/95]
Checking the engine oil level:
*
[SV14000(ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14025(ALL)03/95]
2. Set the parking brake, making sure the
gearshift is securely latched in P (Park).
*
[SV14100(ALL)02/95]
3. Open the hood. Protect yourself from engine
heat.
*
[SV14200(ALL)03/95]

6. Carefully, pull the dipstick out again. If the
oil level is below the ªADD 1 QTº line, add
engine oil as necessary. If the oil level is
beyond the letter ªFº in Full, engine damage
or high oil consumption may occur and
some oil must be removed from the engine.

It may be necessary to add some oil between oil
changes. Make sure you use a CERTIFIED
engine oil of the preferred viscosity. Your
vehicle's warranty coverage may not apply if
engine damage is caused by the use of improper
engine oil.

Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.

[SV17650(ALL)05/95]
The coolant additives also protect the entire
cooling system from internal passageway
corrosion and these additives lubricate the water
pump. The coolant should be serviced as noted
in theMaintenance Schedule and Recordbooklet.
