Octane recommendations
*
[SV08800( ALL)05/95]
Your engine is designed to use 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.
[SV08900( ALL)05/95]
one inch art:0060001-C*
[SV09100( ALL)08/95]
Using a fuel with a lower octane rating can
cause persistent and heavy knocking, which can
damage the engine.
*
[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, see your dealer or a
qualified service technician if persistent heavy
knocking occurs because this can damage the
engine.
*
[SV09350( ALL)05/95]
If your vehicle has problems with 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)06/95]
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%).

[SV10227( ALL)08/95]
Gasoline and gasoline blends may contain small
amounts of carcinogens, such as benzene.
Long-term exposure to unleaded gasoline vapors
has caused cancer in laboratory animals.
*
[SV10230( ALL)08/95]
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.

Running Out of Fuel
*
[SV11350( ALL)09/95]
NOTE: Avoid running out of fuel because this
situation may have an adverse effect on
modern powertrain components.
*
[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]Calculating Fuel Economy
*
[SV11700( ALL)05/95]
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).
*
[SV11750( ALL)05/95]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[SV11800( ALL)05/95]
To calculate fuel economy:
*
[SV11900( ALL)05/95]
1. Fill the fuel tank completely and record the
initial odometer reading.
*
[SV12000( ALL)05/95]
2. Every time you buy fuel, record the
amount (in gallons or liters) purchased.

[SV12100( ALL)05/95]
3. After at least 3-5 tankfuls, fill the fuel tank
and record the final odometer reading.
*
[SV12200( ALL)10/95]
4. Use these equations to calculate your fuel
economy:
*
[SV12250( ALL)10/95]
q
English: MPG = (total miles driven)V
(gallons used)
*
[SV12275( ALL)10/95]

Metric: L/100k = (liters used)V
(100 kilometers)
*
[SV12300( ALL)05/95]
Comparisons With EPA 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.

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.
*
[SV14050(M )03/95]
2. Set the parking brake, making sure that the
gearshift is securely latched in P (Park)
(automatic transmission) or 1 (First) (manual

or at the ªMINº mark (4.6L), add engine oil
as necessary. If the oil level is beyond the
letter ªFº in Full (3.8L) or ªMAXº (4.6L)

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.
*
[SV17850( 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.
