•
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
the International Lubricants Specification
Advisory Committee (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.

Diesel Engine
If you operate your vehicle primarily in any
of the following conditions, you need to
perform extra maintenance as indicated.
If you operate your vehicle
occasionally under any of these conditions, it is not
necessary to perform the extra
maintenance. For specific
recommendations, see your dealership
service advisor or technician. Towing a trailer
Change the engine oil and filter as indicated by the
information display, and perform the services listed in the
scheduled maintenance chart.
As required
See the axle maintenance items under
Exceptions.
Replace the engine-mounted and frame-mounted fuel
filters.
Every 15000 miles (24000
km), 6 months, 600 engine
hours, or as indicated by the
information display
Inspect the coolant concentration (freeze-point protec-
tion) and additive (corrosion inhibitor) strength. Add
coolant additive if necessary.
Every 30000 miles (48000
km) or 1200 engine hours
Flush and refill the coolant. Do not add coolant additive.
Every 60000 miles (96000
km) or 2400 engine hours
Note: When adding coolant additive, do not exceed the specified maximum of 48 fluid
ounces (1.4 liters) for the engine and 16 fluid ounces (473 ml) for the secondary cooling
system. Operating the engine with excessive coolant additive may cause overheating which
could lead to severe, permanent engine damage.

engine hours, flush and fill every 45000 miles (72000 kilometers) or 1800 engine hours
thereafter.
