Service Specifications
- Oil Capacity: 15 quarts (with filter). Always check oil level after refill.
- Oil Drain Plug Torque: 32 ft/lbs.
- OEM Specification Note: The AMSOIL lookup note references Ford Material Engineering Specification WSS-M2C171-F1. It notes that Ford superseded the original WSS-M2C171-D with WSS-M2C171-F1 and recommends meeting this specification for older diesel engines like the 6.4L to provide adequate wear protection.
Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines face unique stresses including soot loading and high heat during heavy towing.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Heavy Duty Towing | Increases engine heat and shear stress. | Signature Series 5W-40 DEOQT-EA | Maintains proper viscosity and provides extreme-pressure protection. | Requires regular monitoring. |
| Engine Wear | Contaminants can cause premature component failure. | Signature Series 10W-30 DTTQT-EA | Delivers up to 6X more wear protection based on Detroit Diesel testing. | Not a repair for existing damage. |
| Filter Restriction | Clogged filters reduce lubrication flow. | AMSOIL Oil Filter EA15K88-EA | Provides 99% efficiency at 20 microns and lower restriction. | Must be replaced per service interval. |
Diesel maintenance notes for this vehicle
Owners of the 6.4L Power Stroke should prioritize high-quality filtration and cooling system integrity. Because these engines are often used for heavy towing or commercial work, maintaining proper oil viscosity is essential to protect turbochargers and high-pressure fuel systems.
Common maintenance concerns for this vehicle

About this vehicle
The 2009 Ford F-250 HD is a prominent member of the Ford Super Duty series, designed to provide significantly higher payload and towing capacities than consumer-oriented models like the F-150. As a Class 2 or 3 truck, it features dedicated chassis components engineered for demanding work, such as heavy towing, commercial applications, or agricultural tasks.
This specific model is equipped with the Ford Power Stroke V8 diesel engine (6.4L Engine Code R). The Super Duty series has been a staple of Ford’s lineup since 1999, serving those who require more robust mechanical capabilities than standard light-duty pickups. Maintenance for this vehicle typically focuses on the unique requirements of high-pressure diesel systems and turbocharger longevity. Owners often prioritize fuel quality, cooling system integrity, and robust filtration to protect sensitive engine components.
Because of the specialized nature of the 6.4L Power Stroke, owners should strictly follow manufacturer specifications for service intervals regarding oil, fuel filters, and coolant. As noted in research, specific technical nuances of this engine may require verification through official Ford technical documentation or a dedicated service manual.
