Capacity by Engine Option

Oil Change Interval

Ford recommends using its Intelligent Oil-Life Monitor (IOLM) to determine the oil change interval. However, a general guideline is:

• Normal Duty: 7,500-10,000 miles or as indicated by the IOLM.
• Severe Duty: 5,000 miles. Severe duty includes frequent towing, extensive idling, or driving in extremely dusty conditions.

Drain Plug Torque

• Drain Plug Torque: 15-20 lb-ft.
• Crush Washer: It is recommended to replace the crush washer on the drain plug at every oil change to prevent leaks. If a new washer is not available, inspect the old one for damage before reusing.

How to Change the Oil

1. Warm up the engine for a few minutes to allow the oil to flow more easily.
2. Position a drain pan under the oil pan and remove the drain plug.
3. Allow the oil to drain completely, then replace the drain plug with a new crush washer and torque to specification.
4. Locate and remove the oil filter. Be prepared for some oil to spill.
5. Apply a thin layer of new oil to the gasket of the new filter and install it hand-tight, plus an additional quarter turn.
6. Fill the engine with the correct amount and type of new oil.
7. Start the engine, let it run for a minute, then shut it off and recheck the oil level, adding more if necessary.
8. Reset the oil life monitor.

Common Issues / Tips

• For the 6.7L Power Stroke, the oil filter is located on the top of the engine, making for a relatively clean filter change. However, ensure the old filter gasket comes off with the old filter to prevent a double-gasket situation which can cause a major oil leak.
• The 6.2L V8 gas engine is known for its reliability, but it is sensitive to oil quality. Using the correct specification oil is crucial for the variable valve timing (VCT) system.
• When changing the oil on the 6.7L Power Stroke, it's a good time to inspect the fuel filters as they have a similar change interval. The diesel fuel filter set consists of two filters, one in the engine bay and one on the frame rail.
