2015 FORD F450 octane

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.
