Oil Change Interval

Ford recommends the following oil change intervals for the 2021 F-250 Super Duty:

• Normal Duty: Every 7,500 to 10,000 miles or every 6 months, whichever comes first.
• Severe Duty: Every 5,000 miles or every 6 months, whichever comes first.

Severe duty conditions include frequent towing or hauling, extensive idling, extreme temperatures, or dusty environments. If you frequently operate your F-250 under these conditions, it's wise to follow the severe duty schedule to ensure optimal engine protection and longevity.

Drain Plug Torque

• 6.2L V8 & 7.3L V8: 19 lb-ft (25 Nm)
• 6.7L Power Stroke V8 Diesel: 20 lb-ft (27 Nm)

Always use a new drain plug crush washer with every oil change to prevent leaks. The crush washer ensures a proper seal and prevents overtightening damage to the oil pan.

How to Change the Oil

1. Gather your supplies: Correct oil, oil filter, drain pan, wrench for the drain plug, oil filter wrench, and a new crush washer.
2. Warm up the engine: Drive the truck for a few minutes to get the oil to operating temperature, which helps it drain more easily.
3. Lift and secure: Safely lift the front of the truck using a jack and secure it with jack stands. This provides access to the oil drain plug and filter.
4. Locate and drain: Place the drain pan under the oil pan. Remove the drain plug and allow all the old oil to drain completely. Inspect the old oil for any metal shavings or unusual consistency.
5. Replace drain plug: Once drained, reinstall the drain plug with a new crush washer and tighten to the specified torque.
6. Remove old filter: Position the drain pan under the oil filter. Use an oil filter wrench to remove the old filter. Be prepared for some oil to spill.
7. Install new filter: Apply a thin film of clean oil to the new filter's rubber gasket. Screw on the new filter by hand until it's snug, then tighten an additional 3/4 turn. Do not overtighten.
8. Refill with new oil: Carefully refer to the capacity chart above and slowly pour the specified amount of new oil into the engine's oil fill cap.
9. Check oil level: Start the engine and let it run for a few minutes. Turn it off, wait a few minutes for the oil to settle, then check the oil level with the dipstick. Add more oil if needed.
10. Inspect for leaks: Double-check the drain plug and oil filter for any signs of leaks.
11. Reset oil life monitor: Consult your owner's manual for instructions on how to reset the oil life monitor.

Common Issues / Tips

• 6.7L Power Stroke Diesel Fuel Filter Changes: It's crucial to also frequently change your fuel filters on the 6.7L Power Stroke. Consult your owner's manual for specific intervals, but typically this is around every 20,000 to 30,000 miles.
• Check for Leaks: The 6.7L Power Stroke can occasionally develop minor oil leaks around the turbocharger or vacuum pump. Keep an eye out for any drips.
• Use the Right Spec: Especially for the Power Stroke diesel, using the correct Ford WSS-M2C171-F1 specification oil is critical for proper emission system function and engine longevity. Deviating from this spec can lead to costly repairs.
• Monitor Oil Life Monitor (OLM): While 10,000 miles might be the maximum for normal duty, your F-250's OLM might suggest an earlier change based on your driving habits. It's always best to follow the OLM.
