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 you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
SWITCHING OFF THE ENGINE
- 6.7L DIESEL
Switch the ignition off.
To help prolong engine life, we
recommended you allow the engine to idle
for three to five minutes, especially after
any of the following:
•
Continuous engine speed.
• High ambient temperature.
• High GVW or GCW operation, for
example heavy loads or trailers.
This allows the turbo charged engine to
cool down.
ENGINE IDLE SHUTDOWN (IF
EQUIPPED)
Your vehicle may be equipped with an
engine idle shutdown system. This system
automatically shuts down your engine
when it has been idling in
P (Park) or N
(Neutral) for five minutes (parking brake
set) or 15 minutes (parking brake not set).
When the engine idle shutdown process
has started: •
A chime sounds and the information
display will show ENGINE TURNS OFF
IN 30 (seconds) and start counting
down
• You can restart the five or 15-minute
timer by changing the position of the
accelerator pedal, brake pedal or the
park brake within the final 30 seconds
• When the timer reaches zero, the
engine shuts down and this message
will appear in your information display
ENGINE TURNED OFF
• One minute after the engine has shut
down, the electrical system simulates
key off, even though the ignition is still
in the on position, initiating normal
accessory delay period
• You must move the ignition to the off
position to reset the system before
restarting your vehicle.
The engine idle shutdown idle timer does
not start if:
• The engine is operating in power
take-off mode.
• The engine coolant temperature is
below 60°F (16°C).
• The exhaust emission control device is
regenerating.

FUEL QUALITY - DIESEL
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)
Note:
Your warranty will not cover damage
caused by using an improper type of fuel or
fuel additive.
Note: 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.
We recommend Top Tier diesel fuel where
available to help minimize engine deposits
and maintain optimal vehicle and engine
performance. For additional information,
refer to www.toptiergas.com.
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
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. Using low sulfur diesel fuel
(16-500 ppm) or high sulfur
diesel fuel (greater than 500
ppm) in your diesel engine 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 19°F (-7°C), we
recommended using a diesel fuel which
has been seasonally adjusted for the
ambient conditions.
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 an 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 coolant
system damage, engine overheating,
selective catalyst reduction system or
diesel particulate filter damage and
possible base engine damage.
Use only a diesel engine 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.
Vehicles with engines configured for use
with high sulfur diesel fuel are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in a ultra low sulfur
diesel fuel market that are subsequently
187
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Fuel and Refueling

exported to non- ultra low sulfur diesel 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- ultra low sulfur diesel
fuel.
Biodiesel WARNING: Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You may operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
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
See General
Maintenance Information (page 565). •
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
frequent LOW FUEL PRESSURE
message appearing
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 or damage to fuel
system components, including fuel pump
and fuel injector failures.
We recommend SAE 5W-40 oil for fuels
with greater than 5% biodiesel (B5). For
more information about oil change
intervals and other maintenance when
operating on biodiesel
See Special
Operating Conditions Scheduled
Maintenance
(page 574).
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 you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
