2015 Ford F450 Super Duty Crew Cab Owner Manual Printing 2 - Page 450

Scheduled Maintenance 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. See Capacities and Specifications (page 300). Additional Axle Maintenance for F-450 and F-550 Change rear axle fluid every 100000 miles (160000 kilometers) under normal driving conditions on all commercial applications. When operating your vehicle at or near maximum gross vehicle weights, change the rear axle fluid every 50000 miles (80000 kilometers). In addition, follow this 50000-mile (80000-kilometer) schedule when operating your vehicle under the special operating conditions, where noted. 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 3000 miles (5000 kilometers). If the available API SM or SN oils are not available, then the oil change interval is 1800 miles (3000 kilometers). Engine Air Filter and Cabin Air Filter Replacement The life of the engine air filter and cabin 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 and cabin air filter. Diesel Particulate Filter The filter may need to be removed for ash cleaning at approximately 120000 miles (192000 kilometers) or greater (actual mileage can vary greatly depending upon engine and vehicle operating conditions) and replaced with a new or re-manufactured (ash cleaned) part. The filter may need to be replaced at approximately 250000 miles (400000 kilometers) depending upon engine and vehicle operating conditions. In both cases, the engine control system sets a service light (wrench icon) to inform you to bring your vehicle to the dealer for service. If there are any issues with the oxidation catalyst or particulate filter system, a service light (wrench or engine icon) sets by the engine control system to inform you to bring your vehicle into a dealer for service. 447 Super Duty (), enUSA
