If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
•
Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
Note: An engine block heater is
recommended at temperatures below
– 10°F (– 23°C).
Engine Oil Specifications
The use of correct oil viscosities for diesel
engines is important for satisfactory
operation. Determine which oil viscosity
best suits the temperature range you
expect to encounter for the next service
interval from the following SAE viscosity
grade chart. 438

Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting 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.

If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
•
Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
We recommend Motorcraft® motor oil for
your vehicle. If Motorcraft® oil is not
available, use motor oils of the
recommended viscosity grade that meet
API SN requirements and display the API
Certification Mark for gasoline engines. Do
not use oil labeled with API SN service
category unless the label also displays the
API certification mark. An oil that displays this symbol conforms
to current engine, emission system and
fuel economy performance standards of
ILSAC.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.
Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting 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.
Note: Automatic transmissions that require
MERCON® LV transmission fluid should
only use MERCON® LV transmission fluid.
The use of any other fluid may cause
transmission damage.
Alternative Engine Oil for
Extremely Cold Climates
To improve engine cold start performance,
we recommend that you use the following
alternative engine oil in extremely cold
climates, where the ambient temperature
reaches -22°F (-30°C) or below.

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 337).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
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.
