How many gallons of oil does a 6.7 powerstroke diesel take?

The engine typically requires about 8.5 gallons of oil for a full change with the filter installed (34 quarts). Without the oil filter, the capacity is around 7.75 gallons (31 quarts).

The 6.7L Power Stroke is a large, turbocharged diesel used in Ford Super Duty trucks, and its oil capacity is correspondingly substantial. Official specifications list 34 quarts with the filter in place, with about 31 quarts as the figure without the filter. Variations can occur by model year, configuration, and whether an oil cooler or other accessories affect capacity. Always refer to your owner's manual or service data for the exact value on your vehicle.

Capacity at a glance

Here are the commonly cited figures you’ll encounter when planning oil changes for a 6.7L Power Stroke.

• With filter: 34 quarts (8.5 gallons).

What kind of oil does a 2019 f250 6.7 take?

For a 2019 Ford F-250 with a 6.7L engine, the recommended oil is SAE 10W-30 meeting specification WSS-M2C171-F1 for normal duty. For severe service (such as towing, heavy loads, or using biodiesel blends), use SAE 5W-40 or 15W-40. In extreme cold, 0W-40 can be used. 
Standard and severe duty

• Standard: Use SAE 10W-30 meeting Ford specification WSS-M2C171-F1. 
• Severe duty: For towing, heavy use, or biodiesel blends, use SAE 5W-40 or 15W-40. 
• Extreme cold: Use 0W-40 in temperatures below -22∘Fnegative 22 raised to the composed with power cap F−22∘𝐹 (-30∘Cnegative 30 raised to the composed with power cap C−30∘𝐶). 

Other considerations

• Engine oil capacity: The 6.7L engine holds 13 quarts with the filter. 
• Oil specification: Always ensure the oil meets the Ford specification WSS-M2C171-F1 or the appropriate CK-4 rating for diesel engines. 
• Full synthetic: Using a 5W-40 full synthetic oil is recommended for its better performance in both cold and hot weather compared to standard 10W-30. 

What oil does a Ford 6.7 diesel recommend?

The recommended oil for a 6.7 Powerstroke is SAE 10W-30, which meets the Ford spec WSS-M2C171-F1 for normal operation. For severe conditions, such as heavy towing or cold weather, SAE 5W-40 is often recommended. In extremely cold temperatures below -22∘Fnegative 22 raised to the composed with power cap F−22∘𝐹 (-30∘Cnegative 30 raised to the composed with power cap C−30∘𝐶), SAE 0W-40 is suggested. 
Primary recommendation

• SAE 10W-30: The primary recommendation for most conditions, meeting the WSS-M2C171-F1 specification. 

Conditions requiring a different oil

• Severe duty or cold weather: Use SAE 5W-40. This is ideal for frequent towing, high-load situations, or if your truck is operated in colder climates.
• Extreme cold: In temperatures below -22∘Fnegative 22 raised to the composed with power cap F−22∘𝐹 (-30∘Cnegative 30 raised to the composed with power cap C−30∘𝐶), switch to SAE 0W-40. 

Important considerations

• Check your owner's manual: Always consult your specific owner's manual for the definitive oil recommendation for your vehicle. 
• Meet specifications: Ensure the oil you choose meets the Ford WSS-M2C171-F1 specification for the best performance and protection.
