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 required 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. Non-synthetic rear axle lubricants should be replaced every 3,000 miles (5,000 km) or 3
months, whichever occurs first, during extended trailer tow operation above 70°F (21°C) ambient and wide open throttle for
extended periods above 45 mph (72 km/h). The 3,000 mile (5,000 km) lube 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 four ounces (118 mL) of additive friction modifier C8AZ-19B546-A (EST-M2C118-A) or equivalent for com-
plete refill of Traction-Lok rear axles. The axle lubricant should be changed anytime an axle has been submerged in water.
E-450, F-450 and F-550 Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km) under normal driving conditions on all F-450 and F-550
commercial applications. For F-450 and F-550 trucks operated at or near maximum Gross Vehicle Weights, the rear axle
lubricant should be replaced every 50,000 miles (80,000 km). In addition, this 50,000 mile (80,000 km) schedule should
be observed when the vehicles are operated under the Special Operating Conditions, where noted.
Diesel Particulate Filter (DPF) (F-Super Duty only)
❑The DPF may need to be removed for ash cleaning at approximately 120,000 miles (193,000 km) or greater (actual mile-
age can vary greatly depending upon engine/vehicle operating conditions) and replaced with a new or remanufactured (ash
cleaned) part. The filter may need to be replaced at approximately 250,000 miles (400,000 km) depending upon engine/
vehicle operating conditions. In both cases the engine control system will set a service light (
) to inform you to
bring the vehicle to the dealer for service. If there are any issues with the oxidation catalyst/DPF system a service light
(
or) will be set by the engine control system to inform you to bring the vehicle into a dealership for
service.
Biodiesel (E-Series only)
❑Biodiesel may be blended with petroleum-based diesel fuel. Such biodiesel blends are designated as BXX, where XX repre-
sents the percentage of pure biodiesel contained within the blend (e.g., B5, B20, and B100). To maintain the desired level
of performance and longevity of the engine, vehicles using biodiesel up to and including B5 should change the engine oil
and filter every 5,000 miles (8,000 km) or 200 hours of engine operation (whichever comes first).
