Oil Change Interval

Ford recommends the following oil change intervals for the 2018 F-250 Super Duty:

• Normal Duty: Every 7,500 to 10,000 miles or 6 to 12 months, whichever comes first. The Intelligent Oil-Life Monitor (IOLM) system will indicate the optimal time based on driving conditions.
• Severe Duty (e.g., heavy towing, prolonged idling, extreme temperatures, dusty conditions): Every 5,000 miles or 6 months, whichever comes first. For diesel engines operating under severe conditions, some sources recommend as frequently as 3,000-5,000 miles.

Always refer to your vehicle's owner's manual and the Intelligent Oil-Life Monitor for the most accurate and personalized recommendations.

Drain Plug Torque

• 6.2L V8 Petrol: 19 ft-lbs (25 Nm). Always replace the drain plug gasket/crush washer.
• 6.7L Power Stroke V8 Diesel: 35 ft-lbs (47 Nm). Always replace the drain plug gasket/crush washer.

How to Change the Oil

1. Warm Up Engine: Drive the truck for a few minutes to bring the oil to operating temperature. This helps the oil drain more completely.
2. Lift and Secure: Safely lift the front of the truck using a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.
3. Locate and Drain: Place a drain pan under the oil pan. Locate the drain plug and carefully remove it with a wrench, allowing the old oil to drain completely. Replace the crush washer.
4. Remove Old Filter: Locate the oil filter. Place the drain pan underneath the filter as well. Carefully unscrew the old oil filter. Be aware that more oil will spill out.
5. Prepare New Filter: Apply a thin layer of new oil to the rubber gasket of the new filter. This helps ensure a good seal.
6. Install New Filter: Hand-tighten the new oil filter until snug, then turn an additional 3/4 to 1 full turn (or as specified by the filter manufacturer). Do not overtighten.
7. Reinstall Drain Plug: Once the oil has finished draining, clean the area around the drain plug. Install the new crush washer on the drain plug and tighten it to the specified torque.
8. Add New Oil: Lower the truck. Locate the oil filler cap on top of the engine. Using a funnel, slowly add the recommended amount and type of new engine oil.
9. Check Level: Start the engine and let it run for a minute to circulate the oil. Turn off the engine, wait a few minutes, then check the oil level with the dipstick. Add more oil if necessary, but be careful not to overfill.
10. Reset Monitor: Reset the Intelligent Oil-Life Monitor (IOLM) system according to your owner's manual.

Common Issues / Tips

• 6.7L Diesel Fuel Filter Reminder: For diesel owners, remember that the 6.7L Power Stroke also has a primary and secondary fuel filter that require regular replacement, often coinciding with oil change intervals under severe duty. Consult your owner's manual.
• Oil Type for Diesels: While 10W-30 is specified for the 6.7L Power Stroke, many owners in colder climates or those who frequently tow opt for a high-quality 5W-40 synthetic diesel oil for better cold-start protection and overall performance.
• Filter Quality: Especially for the 6.7L Power Stroke, using high-quality OEM or reputable aftermarket oil filters is crucial due to the engine's advanced design and filtration requirements.
• Check for Leaks: After an oil change, always check under the truck for any signs of leaks around the drain plug and oil filter area.
