FORD 2001 Taurus - Manual (Page 194)

• FFV fuel tanks may contain zero to 85 percent ethanol. Any fuel
blends containing gasoline and ethanol should be treated the same as
“Fuel Ethanol (E85)”. 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 “K.”
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
d
100 meaning 100% pure ethanol
diluted by 2% to 5% gasoline as the “denaturant.”
Fuel ethanol (E85)
d
is 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 to Cold
Weather Starting in the Starting chapter.
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.
