2001 FORD TAURUS octane

Service engine soon
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD II). The OBD II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD II system also assists the
service technician in properly servicing your vehicle.
The
indicator 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 thelight illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause your
light 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,
the
light 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 the
light remains on, have your vehicle serviced at the first
available opportunity.
Instrumentation

²FFV fuel tanks may contain zero to 85 percent ethanol. Any fuel
blends containing gasoline and ethanol should be treated the same as
ªFuel Ethanol (E85)º. To identify if your vehicle is an FFV, check your
VIN or the label on the inside of your fuel filler door. When checking
the VIN look for the engine type identifier (8th character). If your
vheicle is an FFV, then the character will be labeled as a ªK.º
Pure ethanol is the alcohol which is the intoxicating agent in liquor, beer
and wine. It is distilled from the fermentation of plants such as field corn
and sugar cane. When ethanol is used in the making of motor fuels, a
small amount of a bad tasting chemical is added to discourage beverage
use. The resulting fuel is called E
d100 meaning 100% pure ethanol
diluted by 2% to 5% gasoline as the ªdenaturant.º
Fuel ethanol (E85)
dis then made by adding 15% more unleaded
gasoline. The resulting fuel also has a higher octane rating than unleaded
regular gasoline and other properties which allow engine designs with
greater efficiency and power.
Winter blends may contain up to 30% (E70)unleaded gasoline (25% plus
the denaturant) to enhance cold engine starts. Severely cold weather
may require additional measures for reliable starting. Refer toCold
Weather Startingin theStartingchapter.
Ethanol is more chemically active than gasoline. It corrodes some metals
and causes some plastic and rubber components to swell, break down or
become brittle and crack, especially when mixed with gasoline. Special
materials and procedures have been developed for flexible fuel vehicles
and the dispensers used by ethanol fuel providers.
Flexible fuel components and standard unleaded gasoline fuel
components are not interchangeable. If your vehicle is not
serviced in accordance with flexible fuel vehicles procedures, damage
may occur and your warranty may be invalidated.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.

The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
If your vehicle is a flexible fuel vehicle (FFV), use only UNLEADED
FUEL and ETHANOL(E85). The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
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
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.
Unleaded Gasoline engines
Your vehicle is designed to use ªRegularº unleaded gasoline with an
(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.
87(R+M)/2 METHOD
Maintenance and care
196

FFV engine (if equipped)
Your vehicle is designed to use Fuel Ethanol(E85), ªRegularº unleaded
gasoline or any percentage of the two fuels combined.
U.S. government regulations require fuel ethanol dispensing
pumps to have a small, square, orange and black label with the
common abbreviation E85 or the appropriate percentage for that
region. Use of other fuels such as Fuel Methanol may cause
powertrain damage, a loss of vehicle performance, and your
warranty may be invalidated.
Fuel quality
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.
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.
Unleaded Gasoline engines
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.
FFV engine (if equipped)
Your FFV will operate well on ordinary ªRegularº unleaded gasoline, but
only the highest quality fuel ethanol will provide the same level of
protection and performance. To identify if your vehicle is an FFV, check

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km±5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section ofthe Capacities and specificationschapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
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.
