Understanding the F-250 Super Duty Service Schedule

The F-250 Super Duty service schedule may vary slightly depending on model year, engine type (gas or Power Stroke diesel), and how you use your truck. However, the general intervals below offer a helpful guide to staying ahead of wear and tear. Always consult your owner’s manual or a Ford-certified technician for model-specific details.

Every 5,000–7,500 Miles (Oil Changes and Inspections)

Start with the basics. Every 5,000 to 7,500 miles, your F-250 should get an oil and filter change. This keeps your engine clean and running efficiently. It’s also the right time to rotate your tires, inspect your brakes, and check fluid levels, including engine coolant and transmission fluid.

15,000–20,000 Miles (Mid-Level Maintenance)

Once your odometer hits 15,000 miles, it’s time to go a bit deeper. Replace the engine air filter if it’s dirty or clogged, and inspect the cooling system, exhaust components, and brake lines. If your truck has four-wheel drive, make sure the front axle and steering linkage are properly lubricated and in good condition.

30,000 Miles (Fuel and Cabin System Checks)

At 30,000 miles, inspect belts and hoses for any signs of wear. Replace the cabin air filter to keep your interior airflow fresh. For diesel models, this is a crucial time to replace the fuel filter to protect the injectors and improve fuel efficiency. These maintenance steps help ensure smooth performance and clean emissions.

60,000 Miles (Transmission and Drivetrain)

When your truck crosses the 60,000-mile threshold, transmission service becomes essential. Replace the transmission fluid if needed and inspect the transfer case and differential for leaks. Proper drivetrain maintenance keeps power delivery smooth—especially when towing or off-roading.

100,000 Miles (Major Service Milestone)

This is where long-term care really pays off. If your F-250 uses a gasoline engine, replace the spark plugs at this point. A full coolant flush is also recommended to keep the engine operating at a safe temperature. Inspect suspension components to ensure your truck handles well and rides safely.

F-250 Super Duty Service Intervals for Diesel Engines

If you drive a diesel F-250, your service intervals include some additional steps. Diesel engines are more sensitive to dirty fuel and fluid issues, so it’s important to:

1. Replace the fuel filter more frequently

2. Drain the fuel/water separator regularly

3. Refill the diesel exhaust fluid (DEF) tank

4. Monitor coolant additives to prevent internal corrosion

Diesel maintenance might be a bit more involved, but it helps extend engine life and maintain power under load.

Lighting Maintenance and SEALIGHT LED Upgrades

Routine service isn’t just about the engine and tires. Lighting maintenance is just as important—especially for a heavy-duty truck that works early mornings, late nights, or in remote areas. If your factory headlights are growing dim or yellowed, you’re losing visibility—and that can become a safety risk.

SEALIGHT offers a wide range of LED headlight upgrades designed specifically for trucks like the F-250 Super Duty. Our bulbs deliver crisp, white light with a long beam range and wider coverage, helping you see further and react faster. They also last significantly longer than halogen bulbs and are built to handle vibration and temperature extremes common in truck use. Best of all, most SEALIGHT bulbs are plug-and-play for quick installation with no tools or rewiring.

Pay Attention Between F-250 Super Duty Service Intervals

Scheduled service is essential, but don’t ignore the signs of trouble between visits. If your dashboard lights come on, your steering feels off, or you hear strange noises, take action right away. Many small issues—if caught early—can be fixed quickly and affordably. Waiting too long could mean more downtime or higher costs.

Conclusion

Your Super Duty is more than just a vehicle—it’s a tool you rely on. Following a regular F-250 Super Duty maintenance schedule helps you stay prepared, avoid unexpected problems, and get more from every mile. Keep up with your F-250 Super Duty service intervals, stay alert to warning signs, and don’t forget that visibility matters.
