EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance
❑Rear axles and power take-off (PTO) units containing synthetic lubricant and light duty trucks equipped with Ford-design
axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is re-
quired or the axle assembly has been submerged in water. The axle and PTO lubricant should be changed anytime the axle
and PTO have been submerged in water. During extended trailer tow operation above 70°F (21°C) ambient and wide open
throttle for extended periods above 45 mph (72 km/h), non-synthetic rear axle lubricants should be replaced every
3,000 miles (4,800 km) or three months, whichever occurs first. The 3,000 mile (4,800 km) lubricant change interval
may be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-
Lok rear axles (refer to
Maintenance product and specificationsin theMaintenance and Specificationschapter for details).
The axle lubricant should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery vehicle axle maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km). Rear axle lubricant change may be waived if the axle
was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B or
equivalent. Add four ounces (118 mL) of friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-
Lok rear axles. The axle lubricant should be changed anytime the axle has been submerged in water.
California fuel filter replacement
❑If vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this main-
tenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life.
Ford Motor Company, however, urges you to have all recommended maintenance services performed at the specified inter-
vals and to record all vehicle service.
Hot climate oil change intervals
❑If operating conditions are normal and you drive your Ford, Lincoln or Mercury vehicle under typical, everyday conditions
andyou are using an API performance category oil of SL or later (for example SM, etc.) then you can follow the
7,500 mile (12,000 km) normal service oil change intervals schedule. Vehicles operating in the Middle East, North Africa,
Sub-Saharan Africa or locations with similar climates must follow the oil change interval of 3,000 mile (5,000 km) if the
owner is using oils defined by the American Petroleum Institute (API) performance category of API SK or earlier (for ex-
ample SJ, etc.).
Engine air filter & cabin air filter replacement
❑Engine air filter and cabin air filter life is dependent on exposure to dusty and dirty conditions. Vehicles operated in these
conditions will require frequent inspection and replacement of the engine air filter and cabin air filter.
