octane Mercury Mountaineer 2001 Owner's Manuals

These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theCheck
Enginelight should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap
Momentarily illuminates when the
ignition is turned to the ON position
to ensure your bulb is working.
When this light turns on, check the
fuel filler cap. Continuing to operate the vehicle with the check fuel cap
light on, can activate theService Engine Soon/Check Enginewarning
light. When the fuel filler cap is properly re-installed, the light(s) will
turn off after a period of normal driving. This period will vary depending
on driving conditions.
It may take a long period of time for the system to detect an
improperly installed fuel filler cap.
For more information, refer toFuel filler capin theMaintenance and
carechapter.

Octane recommendations
Your vehicle is designed to use
ªRegularº unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as ªRegularº that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your dealer or a qualified
service technician to prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº unleaded
gasoline. ªPremiumº unleaded gasoline is not recommended (particularly
in the United States) because it may cause these problems to become
more pronounced. If the problems persist, see your dealer or a qualified
service technician.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world's automakers
issued the World-wide Fuel Charter
that recommends gasoline
specifications to provide improved
performance and emission control
system protection for your vehicle.
Gasolines that meet the World-wide
Fuel Charter should be used when
available. Ask your fuel supplier
about gasolines that meet the
World-wide Fuel Charter. In Canada,
look for fuels that display theAuto Makers' Choiceylogo.
Cleaner air
Ford endorses the use of reformulated ªcleaner-burningº gasolines to
improve air quality.

Maintenance and care

For consistent results when filling the fuel tank:
²Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow no more than 2 automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in kilometers or miles).
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Multiply liters used by 100, then divide by total kilometers
traveled.
Divide total miles traveled by total gallons used.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle's fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.

4.0L vehicles with limited slip differentials and all 5.0L applications use
rear axles that are filled with Motorcraft SAE 75W-140 High Performance
Synthetic Rear Axle Lubricant, part number F1TZ-19780-B, Ford

4.0L vehicles with limited slip differentials and all 5.0L applications must
add 118 ml (4 oz) of Additive Friction Modifier C8AZ-19B546-A or
equivalent meeting Ford specification EST-M2C118-A to the rear axle
whenever the axle has been serviced.
