6.7L Power Stroke Service Information

6.7L Power Stroke Maintenance Schedule, Service Part Numbers, Fluid Specs

"Severe" duty conditions include any or any combination of the following:

• Excessive idling
• Frequent short trips in which the engine is shut-down before reaching full operating temperature
• Driving on dusty roads
• Driving off-road or in conditions that require 4 wheel drive
• Frequent towing or hauling (with the exception of very light loads)
• Using biodiesel blends greater than B5 (applies to oil, fuel filters only)

As a general rule of thumb, always abide by the "Severe Duty" service schedule if your vehicle is used in any strenuous activity, i.e. is subjected to more rigorous conditions than normal, unladen driving.

[1] Fuel filters sold as a kit with chassis mounted and engine mounted filters.
[2] 2011 model year vehicles featured a plastic 1/4 turn drain plug.
[3] Verify correct glow plug for application; engines built before 12/1/2012 require ZD-17 glow plugs, while later 2012 - 2019 engines require ZD-18 glow plugs. ZD-17 glow plugs are 91 mm long, while the ZD-18 glow plugs are 96 mm long. 2020+ model year vehicles require ZD-26 glow plugs.
[4] Primary cooling system refers to the high temperature system that manages engine cooling.

[1] Listed capacities are nominal and may vary; always replenish oils and fluids to the proper dipstick indicator or fill plug level while the vehicle is parked on a level surface.
[2] Engine oils used in the 6.7L Power Stroke must meet, at minimum, API CJ-4 and Ford engineering specification WSS-M2C171-F1. API CK-4 engine oils do not always adhere to Ford's engine oil criteria. 5W-40 engine oil required for vehicles placed in the "severe duty" service category. 5W-40 or 15W-40 engine oil required for vehicles using biodiesel.
[3] Primary cooling system refers to the high temperature engine cooling system.
[4] Secondary cooling system refers to the low temperature cooling system that provides coolant to the air-to-water charge air cooler, EGR cooler, transmission fluid heat exchanger, and fuel cooler.
[5] Models equipped with an electronic locking differential may require a friction modifier; use Motorcraft XL-3.
