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 factory built high-sulfur engine (available as a
dealer order option for select markets) or a ULSD (ultra low sulfur
diesel) fuel configured engine that has been retrofitted for high-sulfur
diesel fuel using Ford Motor Company dealer service parts. Failure to use
retrofit components other than those available through your authorized
dealer will result in engine coolant system damage, engine overheating,
SCR and/or DPF damage and possible base engine damage.

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 using Ford
authorized dealer service parts) 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 or a frequentLOW FUEL
PRESSUREmessage appearing.
•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.
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 D975 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.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meets the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meets the World-wide
Fuel Charter.
Do not blend used engine oil with diesel fuel under any
circumstances.Blending used oil with the fuel will significantly increase
your vehicle’s exhaust emissions and reduce engine life due to increased
internal wear.
Diesel fuel conditioner
Additives that will improve fuel cetane numbers may be used to
verify/enhance fuel quality. Use Motorcraftor an equivalent cetane
booster & performance improver as listed in theMaintenance product
specifications and capacitiessection in this chapter. The customer
warranty may be void from using additives that do not meet or exceed
Ford specifications.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/system. Use Motorcraftor an
equivalent anti-gel & performance improver as listed in theMaintenance
product specifications and capacitiessection in this chapter. The
customer warranty may be void from using additives that do not meet or
exceed Ford specifications.
Note:These ultra-low sulfur formulations are designed to meet the
emissions standards for the 6.7L engine and is backward compatible as
well (i.e., can be used in Ford 7.3L, 6.9L, 6.4L and 6.0L diesel engines in
Ford vehicles).
Fueling tips
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. To
purge the air sooner: prior to engine start, prime the system by turning

the key to on for 30 seconds then to off. Repeat this several times. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.
Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from a 1
1 8fuel dispensing nozzle. Pumping fuel
at greater flow rates may result in premature nozzle shut-off or spitback.
Fuel filler cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraftfuel filler cap is not used.
WARNING: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.

WARNING: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.
Selective Catalytic Reduction (SCR) System
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. However, certain conditions or
driving styles, such as trailer towing or fast rates of acceleration, will
require the refilling of the DEF tank more often.
The engine control unit will monitor the amount of fluid available in the
DEF tank. Running a system check in the message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. SeeMessage centerin theInstrument Clusterchapter of
yourOwner’s Guidefor message center functions. For instructions on
refilling your DEF tank, seeFilling the DEF tanklater in this section.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the vehicle speed will be
speed limited to 50 mph (80 km/h). In these conditions, drive with
caution and refill DEF immediately. If the DEF becomes empty or
contaminated fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.
