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.

Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford
Specification EST-M2C118– A for complete refill of limited slip Ford axles. Ford design
rear axles contain a synthetic lubricant that does not require changing unless you submerge
the axle in water.
2 Ford recommends using Motorcraft (Ford) DOT 3 LV High Performance Motor Vehicle
Brake Fluid, Motorcraft (Ford) DOT 4 LV High Performance Motor Vehicle Brake Fluid or
equivalent meeting WSS-M6C65-A1 or WSS-M6C65-A2. Use of any fluid other than the
recommended fluid may cause degraded brake performance and not meet the Ford
performance standards. Keep brake fluid clean and dry. Contamination with dirt, water,
petroleum products or other materials may result in brake system damage and possible
failure.
3 Add the coolant type originally equipped in your vehicle.
4 Ford has designed your engine to use Motorcraft engine oils or equivalent oils that meet
Ford ’s specification. It is also acceptable to use an engine oil of recommended viscosity
grade that meets API SN requirements and displays the API Certification Mark for gasoline
engines.
5 Do not use oils labeled as API SN unless the label also display the API certification mark.
These oils do not meet the requirements of your vehicles engine and emissions system.
6 Do not use supplemental engine oil additives. They are unnecessary and could lead to
engine damage not covered by your Ford warranty.
7 Use the correct automatic transmission fluid. Transmission fluid requirements are
indicated on the dipstick blade or the dipstick handle. Check the container to verify the
fluid you are adding is of the correct type. Refer to your scheduled maintenance information
to determine the correct service interval.
Note: Automatic transmissions that require MERCON LV should only use MERCON LV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.
8 Indicates only approximate dry-fill capacity. Some applications may vary based on cooler
size and if equipped with an in-tank cooler. You should set the amount of transmission
fluid and fluid level by the indication on the dipstick’ s normal operating range.
9 Fill to the proper capacity according to dipstick Type A. For correct dipstick type, See
Automatic Transmission Fluid Check (page 240).
9 Fill to the proper capacity according to dipstick Type B. For correct dipstick type, See
Automatic Transmission Fluid Check
(page 240).
10 See the Warning below: WARNING
The air conditioning refrigerant system contains refrigerant R-134a under high
pressure. Opening the air conditioning refrigerant system can cause personal injury.
Have the air conditioning refrigerant system serviced only by qualified personnel.

Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information. Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
