restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. If you have been using biodiesel, you may need to use a fuel
with lower biodiesel content, try another brand, or discontinue using
biodiesel.
Your vehicle is equipped with a diesel fuel conditioner module (DFCM)
which recirculates fuel from the engine to help prevent fuel filter
clogging. Your vehicle is also equipped with a bypass relief valve, located
in the fuel tank pick-up boot, which provides fuel flow to the engine if
the fuel pickup should become plugged. To allow the bypass valve to
function and avoid engine fuel starvation during cold weather operation
of 32°F (0°C) or below, it is recommended that the fuel level in your
tank should not be allowed to drop below
14full. This will help prevent
air from entering the fuel system and stalling the engine.
Your vehicle is equipped with a an SCR system which uses diesel exhaust
fluid (DEF) to operate properly. DEF must be replenished at certain
intervals. When filling the vehicle’s DEF tank in cold weather, special
care must be taken to prevent damage to the DEF tank. For proper cold
weather fill procedure, seeSelective Catalytic Reduction (SCR) System
in theMaintenance and Specificationschapter.
In cold weather below 32°F (0°C), the engine will slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Remove the air
cleaner cover and the pleated paper filter, leaving the foam filter in and
remove any snow or ice. Ensure the foam filter is installed correctly in
place. Remove any debris, snow and/or ice on the foam filter by brushing
the surface with soft brush. Do not use water, solvents, or a hard brush
for cleaning the foam filter.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they are in
optimum condition.
•Use the proper coolant solution at the concentration recommended to
protect the engine against damage from freezing.

•Try to keep the fuel tank full as much as possible at the end of
operation to prevent condensation in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level. Also, if necessary, make sure to follow the engine oil and
filter change schedule found under theSpecial operating conditions
section listed in thescheduled maintenance information.
•At temperatures of -10°F (-23°C) or below, it is recommended that
you use an engine block heater to improve cold engine starting.
•If operating in arctic temperatures of -20°F (-29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Note:Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a buildup of heavy deposits of carbon and rust which can cause engine
damage.
The following cold weather idling guidelines must be followed:
•Avoid idling the engine for more than 10 minutes at a time.
•Use Motorcraftcetane improvers or non alcohol-based cetane
improvers from a reputable manufacturer.
•Maintain the engine cooling system properly.
•Avoid shutting the engine down after an extensive idling period
(10 minutes or more). Drive the vehicle for several miles with the
engine at normal operating temperatures under a moderate load.
•Consider using an engine block heater.
•For extended idle times use an approved idle speed increase device.

Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
Engine block heater (if equipped)
Refer to theDrivingchapter in theOwner’s Guide.
Rapid heat supplemental heating system (if equipped)
The optional rapid heat feature is an electrically powered device that is
designed to provide supplemental heat during engine warm up. For
maximum effectiveness mid to low blower speed is recommended during
initial warm up. When operating in automatic mode (when equipped) the
climate control unit will determine the appropriate blower speed for
existing conditions.
Note:Additional aftermarket electrical loads operated during engine
warm up may impact the performance of the rapid heat supplemental
heater.
DUAL FUEL TANK SELECTOR CONTROL (IF EQUIPPED)
If your vehicle is equipped with dual
fuel tanks, you will have a selector
control, located to the right of the
steering wheel, which allows you to
draw fuel from either tank. Your fuel
gauge will display the amount of
fuel in the currently selected tank.

SCHEDULED MAINTENANCE
The scheduled maintenance services in thescheduled maintenance
informationof this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraftparts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS
REQUIRED (UNITED STATES/CANADA/PUERTO RICO/U.S. VIRGIN
ISLANDS AND OTHER LOCALES)
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel (also known as ULSD) in your 6.7L diesel
engine.The engine and exhaust system were designed to only use this
fuel. Look for theULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(15 ppm Sulfur Maximum)label on fuel pumps when purchasing your
fuel.
Using low sulfur diesel fuel (16-500 ppm) or high sulfur diesel
fuel (greater than 500 ppm) in a diesel engine designed to use
only Ultra Low Sulfur Diesel fuel will cause certain emission
components to malfunction which may also cause the service
engine soon
light to illuminate indicating an emissions-
related concern.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient conditions. See
Cold weather operationin theDrivingchapter of this supplement.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS NOT
REQUIRED
For the engine to operate reliably on low sulfur or high sulfur diesel fuel,
the engine must be a high sulfur configured engine or a ULSD
fuel-configured engine that has been retrofitted for high sulfur diesel fuel
use.
Use only a diesel engine that has been configured for use with
high sulfur diesel fuel in markets with diesel fuel that has sulfur
content greater than 15 ppm. Using low sulfur diesel fuel (16–500
ppm) or high sulfur diesel fuel (greater than 500 ppm) in a diesel

engine designed to use only Ultra Low Sulfur Diesel fuel may
result in damage to engine emission control devices and the
aftertreatment system, potentially rendering the vehicle
inoperable. Engine damage from using the improper type of fuel
is not covered under your warranty.
Vehicles with engines configured for use with high sulfur diesel fuel will
only be made available for sale in countries where ULSD fuel is generally
not available or mandated by the government. Vehicles originally sold in
a ULSD fuel market that are subsequently exported to non-ULSD fuel
markets will need to be retrofitted (at the customer’s expense) in order
to be reliably operated on non-ULSD fuel.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient temperature.
SeeCold weather operationin theDrivingchapter of this supplement.
BIODIESEL
This vehicle may be operated on diesel fuels containing up to 20%
biodiesel, also known as B20.
To help achieve acceptable engine performance and durability when
using biodiesel in your vehicle:
•Confirm the biodiesel content of the fuel to be B20 (20% biodiesel) or
less
•Only use biodiesel fuel of good quality that complies with industry
standards
•Follow the recommended service maintenance intervals section in the
Schedule Maintenancechapter.
•Do not store biodiesel fuel in the fuel tank for more than 1 month
•Consider changing brands or reducing biodiesel content if you have
cold temperature fuel gelling issues
•Do not use raw oils, fats or waste cooking greases
Use of biodiesel in concentrations greater than 20% may cause damage
to your vehicle, including engine and/or exhaust after-treatment
hardware (exhaust catalyst and particulate filter) failures. Concentrations
greater than 20% can also cause fuel filter restrictions that may result in
a lack of power and / or damage to fuel system components, including
fuel pump and fuel injector failures.
Maintenance and Specifications

2011 Econoline(eco)
Supplement, 1st Printing
USA(fus)

5W-40 or 15W-40 oil is recommended for fuels with greater than 5%
biodiesel (B5). Refer to theSpecial operating conditionssection under
theSchedule Maintenancechapter for more information about oil
change intervals and other maintenance when operating on biodiesel.
Look for a label on the fuel pump to confirm the amount of biodiesel
contained in a diesel fuel. Biodiesel content is often indicated with the
letter “B” followed by the percent of biodiesel in the fuel. For example,
B20 indicates a fuel containing 20% biodiesel. Ask the service station
attendant to confirm the biodiesel content of a diesel fuel if you do not
see a label on the fuel pump.
Biodiesel fuels degrade more easily than diesel fuels not containing
biodiesel and should not be stored in the fuel tank for more than
1 month. If your vehicle will be parked or stored for more than 1 month,
then your vehicle fuel tank should be emptied of biodiesel fuel, filled
with a pure petroleum-based diesel fuel, and run for a minimum of
30 minutes.
Note:Degraded or oxidized biodiesel can damage fuel system seals and
plastics and corrode steel parts.
During cold weather, if you have problems operating on biodiesel, you
may need to use a diesel fuel with lower biodiesel content, try another
brand, or discontinue the use of biodiesel.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
NOTbe used.
WARNING:Do not use home heating oil, agricultural fuel or any
diesel fuel not intended for highway use. Damage to the fuel
injection system, engine and exhaust catalyst can occur if an improper
fuel is used. Do not add gasoline, gasohol or alcohol to diesel fuel. This
practice creates a serious fire hazard and engine performance problems.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets either the
ASTM D 975 diesel or the ASTM D7467 B6-B20 biodiesel industry
specifications. Outside of North America, use fuels meeting EN590 or
equivalent local market standard. Aftermarket additives can damage the
injector system or engine. Repairs to correct the effects of using an
aftermarket product in your fuel may not be covered by your warranty.
