octane FORD MUSTANG 2001 4.G Owners Manual

TheService Engine Soonindicator light illuminates
when the ignition is first turned to the ON position
to check the bulb. If it comes on after the engine is
started, one of the engine's emission control systems
may be malfunctioning. The light may illuminate
without a driveability concern being noted. The
vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon
light illuminates
Light turns on solid:
This means that the OBD II system has detected a
malfunction.
Temporary malfunctions may cause yourService
Engine Soonlight to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may
misfire or run poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed
and securely tightened.
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, theService Engine Soonlight
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 theService Engine Soonlight 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.

Repairs to correct the effects of using a fuel for
which your vehicle was not designed may not be
covered by your warranty.
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.
87(R+M)/2 METHOD
Maintenance and care
184

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.
