Diesel Messages Action / Description
LOW FUEL
PRESSUREIf this message appears during a cold start
or during cold operation 32°F (0°C) up to
10 minutes after the initial cold start; monitor
the message center and if it disappears and does
not re-appear after the engine has fully warmed
up, the low fuel pressure message is most likely
caused by waxed or gelled fuel. To prevent this,
use an anti-gel additive. Refer to your diesel
supplement for more information. The customer
warranty may be void from using additives that
do not meet or exceed Ford specifications. If the
low fuel pressure message persistently appears
after re-fueling during the cold start and cold
operation conditions defined previously and then
disappear when the engine has fully warmed up,
consider different fuel sources.
Low Fuel Operation: If the message appears
when the vehicle is warm and during low fuel
tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate
the vehicle. If the message reappears after
fueling, see below. If the message does not come
back, the low fuel pressure condition was due to
low fuel levels in the fuel tank.
Normal Operation: If the message appears during
normal operation when the vehicle / engine is
fully warm, and fuel level is not low, the fuel
filters must be changed regardless of the
maintenance schedule interval. If replacement
of the fuel filter does not remedy the low fuel
pressure message during normal operation as
defined above, please take the vehicle to your
authorized dealer.

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 produced for use in motor fuels,
a small amount of gasoline is added to make it unfit for beverage use.
The resulting ethanol blend is called denatured fuel ethanol meaning that it
is denatured with 2% to 5% gasoline and is suitable for automotive use.
During the summer season, fuel ethanol may contain a maximum of 85%
denatured ethanol (Ed85) and 15% unleaded gasoline. The fuel ethanol
has a higher octane rating than unleaded regular or premium gasoline
and this allows the design of engines with greater efficiency and power.
Winter blends may contain up to 75% denatured ethanol (Ed75) and up
to 25% unleaded gasoline to enhance cold engine starts. Severely cold
weather may require additional measures for reliable starting. Refer to
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.
FUEL QUALITY
Note:Use of any fuel other than those recommended may cause
powertrain damage and a loss of vehicle performance; repairs may not be
covered under warranty.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Choosing the Right Fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 15% ethanol. Do not use fuel ethanol (E85), diesel fuel, fuel-methanol,
leaded fuel or any other fuel because it could damage or impair the
emission control system.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives. The use of leaded fuel
is prohibited by law.
Diesel engine (if equipped)
Refer to the diesel supplement for information regarding diesel fuel
recommendations and requirements of your diesel-powered truck.
