6.7 Power Stroke Maintenance Schedules
Service procedures that are required at a declared vehicle mileage OR time interval should be performed at the point where either the mileage OR the time is reached, whichever should come first. All 6.7L Power Stroke equipped vehicles fall under the "severe" or "heavy duty" service category if any of the following conditions are true:
• Vehicle is frequently driven in heavy stop-and-go traffic conditions, used regularly for short trips that prevent the engine from reaching normal operating temperature, or is idled more than 10 minutes within a 60 minute period of time
• Vehicle is used to tow a trailer or haul heavy cargo
• Vehicle is operated in extremely cold (< 32° F) or extremely hot (> 100° F) ambient conditions
• Vehicle is operated off-road, especially in dusty conditions
• Engine is operated on biodiesel fuel blends
Light, infrequent towing is unlikely to require maintenance intervals under the "severe" service schedule, however if there is any doubt as to which category your vehicle falls under, adhere to the "severe" schedule; most vehicles will fall into this category due to one or more of the listed conditions. It is also important to consider that the 6.7L Power Stroke is a high output engine with a fuel system that is extremely sensitive to contamination. Additionally, it has a highly advanced exhaust aftertreatment system.
Although the 6.7L Power Stroke is certified for biodiesel fuel blends up to B20 (20% biodiesel, 80% petroleum diesel), fuel filter replacements and oil changes should be performed more frequently when operating on biodiesel fuel blends. The 6.7L Power Stroke's electronic oil and fuel system service monitors will not adjust for biodiesel fuel usage. Note that biodiesel has a limited shelf life and should not be stored for long periods (> 3 months). Biodiesel is sometimes marketed as biomass or renewable diesel fuel.

6.7 Power Stroke Oils, Lubricants, & Fluids
Engine Oil Viscosity Chart
Ford's engine oil requirements for the 6.7L Power Stroke are relatively strict due to the fact that formulations meeting API CK-4 specifications were not always found to meet Ford engineer's wear protection requirements. Thus, Ford specifies that engine oils must meet API CJ-4 and Ford WSS-M2C171-F1 specifications. Additional information, including the history on engine oil requirements for the 6.7L Power Stroke can be found here: 6.7 Power Stroke motor oil requirements. Failure to use an appropriate engine oil could result in accelerated engine wear, DPF clogging, and excessive fuel dilution.
