2015 FORD F450 engine

You may experience a decrease in peak
performance when the engine is cold when
operating on E85 ethanol.
Do not crank the engine for more than 10
seconds at a time as starter damage may
occur. If the engine fails to start, turn the
key to off and wait 30 seconds before
trying again.
Do not use starting fluid such as ether in
the air intake system. Such fluid could
cause immediate explosive damage to the
engine and possible personal injury.
If you should experience cold weather
starting problems on E85 ethanol, and
neither an alternative brand of E85 ethanol
nor an engine block heater is available, the
addition of unleaded gasoline to your tank
improves cold starting performance. Your
vehicle is designed to operate on E85
ethanol alone, unleaded gasoline alone, or
any mixture of the two.
If the Engine Fails to Start Using the
Preceding Instructions (Flexible Fuel
Vehicles Only)
1. Press and hold down the accelerator
one-third to one-half the way to the
floor, then crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds
up. If the engine still fails to start,
repeat Step 1.
Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
•
Open the windows at least 1 inch (2.5
centimeters).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. Do not fully close the hood, or allow
it to drop under its own weight when
using the engine block heater. This
could damage the power cable and may
cause an electrical short resulting in fire,
injury and property damage. Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.

Super Duty (), enUSA Starting and Stopping the Engine

We recommend that you do the following
for a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary. The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. Automotive fuels can cause serious
injury or death if you misuse or
mishandle them.
Fuel ethanol and gasoline may
contain benzene, which is a
cancer-causing agent.
When refueling always shut the
engine off and never allow sparks or
open flames near the filler neck.
Never smoke or use a cell phone while
refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. The flow of fuel through a fuel pump
nozzle can produce static electricity,
which can cause a fire if you pump
fuel into an ungrounded fuel container. Observe the following guidelines when
handling automotive fuel: •
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If swallowed, call a
physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind can lead
to eye and respiratory tract irritation.
In severe cases, excessive or prolonged
breathing of fuel vapor can cause
serious illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If
you splash fuel in your eyes, remove
contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper
medical attention could lead to
permanent injury.
• Fuels can also be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
wash your skin thoroughly with soap
and water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
“Antabuse ” or other forms of disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors, or skin
contact could cause an adverse
reaction. In sensitive individuals, serious
personal injury or sickness may result.
If you splash fuel on your skin, promptly
wash your skin thoroughly with soap
and water. Consult a physician
immediately if you experience an
adverse reaction.

FUEL QUALITY
Note:
Do not add after-market fuel additive
products to your fuel tank. We recommend
that you use only high quality fuel without
after-market additives or other engine
treatments.
Note: Your warranty will not cover any
vehicle damage, loss of vehicle performance
or repairs to your vehicle caused by the use
of fuel not recommended.
Choosing the Right Fuel
Use only unleaded gasoline or unleaded
gasoline blended with a maximum of 15%
ethanol in your gasoline vehicle. If your
vehicle is a flex fuel vehicle (FFV), it will
have a yellow cap.
Do not use:
• Fuels containing more than 15%
ethanol or E-85 fuel.
• Fuels containing methanol.
• Fuels containing metallic based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Prohibited by law, you cannot use
leaded fuel.
Diesel Engine
Refer to the diesel supplement for
information regarding diesel fuel
recommendations and requirements of
your diesel-powered truck.
Choosing the Right Fuel With a
Flex Fuel Vehicle (If Equipped)
Note: Flex fuel vehicles will have a yellow
fuel cap. Use only unleaded gasoline or unleaded
gasoline blended with a maximum of 85%
ethanol (E-85) in your flex fuel vehicle
(FFV).
Do not use:
•
Fuels containing more than 85%
ethanol or E-100 fuel.
• Fuels containing methanol.
• Fuels containing metallic based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Prohibited by law, you cannot use
leaded fuel.
Your warranty will not cover any vehicle
damage, loss of vehicle performance or
repairs to your vehicle, caused by the use
of fuel not recommended.
It is best not to alternate repeatedly
between gasoline and E85. If you do switch
fuels, it is recommended that you add as
much fuel as possible—at least half a tank.
Do not add less than 5.0 gal (18.9 L)when
refueling. You should drive the vehicle
immediately after refueling for at least 5.0
(8 km)to allow the vehicle to adapt to the
change in ethanol concentration. The
recommendation if you exclusively use E85
fuel, is to fill the fuel tank with regular
unleaded gasoline at each scheduled oil
change.
Octane Recommendations 140
Super Duty (), enUSA Fuel and RefuelingE161513

We recommend regular unleaded gasoline
with a pump (R+M)/2 octane rating of 87.
Some stations offer fuels posted as regular
with an octane rating below 87, particularly
in high altitude areas. We do not
recommend fuels with an octane rating
below 87.
Do not be concerned if your engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, see your
authorized dealer to prevent any engine
damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you run out of fuel:
•
You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the engine. If
the vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters)
may be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Warning Lamps and Indicators
(page 79). Refilling With a Portable Fuel
Container WARNINGS
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. Do not try to pry open or push open
the fuel system with foreign objects.
This could damage the fuel system
and its seal and cause personal injury to
you or others. Use the following directions when filling
from a portable fuel container:
1.
Remove the fuel cap from the fuel filler
pipe by rotating it counter clockwise.
2. Slowly insert the portable fuel container into the fuel filler opening.
3. Fill the vehicle with fuel from the portable fuel container.
4. When done, remove the portable fuel container nozzle and reinstall the fuel
cap. Insert fuel cap into fuel filler
opening and turn clockwise until you
hear a click.
REFUELING WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions
on the pump island.
Turn off your engine when you are
refueling.
Do not smoke if you are near fuel or
refueling your vehicle.
141
Super Duty (), enUSA Fuel and Refueling

WARNINGS
Keep sparks, flames and smoking
materials away from fuel.
Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle. This is
against the law in some places. Keep children away from the fuel
pump; never let children pump fuel.
Do not use personal electronic
devices while refueling.
Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this
will fill the expansion space in the fuel tank
and could lead to fuel overflowing. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
•
Place approved fuel container on the
ground.
• Do not fill a fuel container while it is in
the vehicle (including the cargo area).
• Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold
the fuel pump handle in the fill position. Fuel Filler Cap WARNINGS
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury. 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. Note:
If you must replace the fuel filler cap,
replace it with a fuel filler cap that is
designed for your vehicle. The customer
warranty may be void for any damage to the
fuel tank or fuel system if the correct
genuine Ford, Motorcraft or other certified
fuel filler cap is not used.
Your fuel tank filler cap has an indexed
design with a 1/4th turn on and off feature.
When fueling your vehicle:
1. Put your vehicle in park (P).
2. Switch the engine off.
3. Carefully turn the filler cap counterclockwise until it spins off.
4. Pull to remove the cap from the fuel filler pipe.
5. To install the cap, align the tabs on the
cap with the notches on the filler pipe.
6. Turn the filler cap clockwise 1/4 of a turn clockwise until it clicks at least
once.
If the Check Fuel Cap light or a Check Fuel
Cap message appears in the instrument
cluster and stays on after you start the
engine, you may not have installed the fuel
filler properly.
142
Super Duty (), enUSA Fuel and Refueling

If the fuel cap light remains on, at the next
opportunity, safely pull off of the road,
remove the fuel filler cap, align the cap
properly and reinstall it. The check fuel cap
light or Check fuel cap message may not
reset immediately. It may take several
driving cycles for the indicators to turn off.
A driving cycle consists of an engine
start-up (after four or more hours with the
engine off) followed by normal city and
highway driving.
FUEL CONSUMPTION
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable
fuel in the empty reserve varies and should
not be relied upon to increase driving range.
•
The usable capacity of the fuel tank is
the amount of fuel that can be added
into the tank after the gauge indicates
empty
• The advertised capacity is the total fuel
tank size. See Capacities and
Specifications (page 301). It is the
combined usable capacity plus the
empty reserve.
• Due to the empty reserve, you may not
be able to refuel the full amount of the
advertised capacity of the fuel tank
even when the fuel gauge reads empty.
Filling the Tank
For consistent results when filling the fuel
tank:
• Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than two automatic
click-offs when filling. Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of
driving (this is your engine
’s break-in
period); a more accurate measurement is
obtained after 2000 miles - 3000 miles
(3200 kilometers - 4800 kilometers). Also,
fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least 3 to 5 tank fill ups, fill the
fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least 1 month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current
driving conditions. Additionally, keeping
records during summer and winter show
how temperature impacts fuel economy.
In general, lower temperatures mean lower
fuel economy.
143
Super Duty (), enUSA Fuel and Refueling

Conditions
•
Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Carrying unnecessary weight may
reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400
pounds [180 kilograms] of weight
carried).
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars/light bars, running boards, ski
racks) may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 8– 10
miles (12 –16 kilometers) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Close windows for high speed driving.
EMISSION CONTROL SYSTEM WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
The emission system heats up the
engine compartment and exhaust system,
which can start a fire. Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes. Your vehicle is equipped with various
emission control components and a
catalytic converter that will enable your
vehicle to comply with applicable exhaust
emission standards. To make sure that the
catalytic converter and other emission
control components continue to work
properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use parts other than Ford, Motorcraft
or Ford-authorized parts for maintenance
replacements, or for service of
components affecting emission control,
such non-Ford parts should be the
equivalent to genuine Ford Motor Company
parts in performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
