Every oil change interval
Exceptions
There are several exceptions to the Normal
Schedule:
Normal vehicle axle maintenance: Rear
axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required or the assembly has been
submerged in water. During long periods
of trailer towing with outside temperatures
above 70°F (21°C) and at wide-open
throttle for long periods above 45 mph
(72 km/h), change non-synthetic rear axle
fluid every 3000 mi (4,800 km) or three
months, whichever comes first. This
interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting
Ford specification WSL-M2C192-A; GL-5
or equivalent. Add friction modifier XL-3
EST-M2C118-A or equivalent for complete
refill of Traction-Lok rear axles. See
Capacities and Specifications (page
265).
Police, Taxi and Livery vehicle axle
maintenance: Change rear axle fluid every
100000 mi (160,000 km). Rear axle fluid
change may be waived if the axle was filled
with 75W140 synthetic gear fluid meeting
Ford specification WSL-M2C192-A; GL-5

Scheduled Maintenance
Exclusive use of E85 (Flex fuel vehicles only)

unleaded fuel.
or equivalent. Add four ounces (118
milliliters) of additive friction modifier XL-3
EST-M2C118-A, or equivalent, for complete
refill of Traction-Lok rear axles. Change
the axle fluid anytime the axle submerges
in water.
California fuel filter replacement: If you
register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
Hot climate oil change intervals:
Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 5000 mi (8,000 km).
If the available API SM or SN oils are not
available, then the oil change interval is
3000 mi (4,800 km).
Engine air filter replacement: The life of
the engine air filter is dependent on
exposure to dusty and dirty conditions.
Vehicles operated in these conditions
require frequent inspection and
replacement of the engine air filter.
