❑
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.
Biodiesel
❑
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).
