Quick reference
| Mileage | Service | Notes |
|---|---|---|
| 5,000 miles | Oil and filter change, Tire rotation, Multi-point inspection | Optimal for regular duty, especially with the 6.7L Power Stroke diesel. For gas engines, 7,500-10,000 miles is typical, but 5,000 miles is a good benchmark for heavy use. |
| 10,000 miles | Oil and filter change, Tire rotation, Basic fluid check, Multi-point inspection | Standard interval for many components. Severe duty might require earlier oil changes. |
| 15,000 miles | Engine air filter inspection, Cabin air filter inspection, Fuel filter inspection (diesel) | Inspect and replace as needed. Fuel filters on diesel engines are critical and may need replacement every 15,000-20,000 miles under severe conditions. |
| 30,000 miles | Engine air filter replacement, Cabin air filter replacement, Fuel filter replacement (diesel), Brake fluid flush, Differential fluid change (rear) | Significant interval. Brake fluid is hygroscopic and should be flushed. Differential fluid replacement is crucial for longevity, especially with towing. Transmission fluid inspection (check level and condition for both gas and diesel). |
| 60,000 miles | Transmission fluid and filter service (gasoline engines), Coolant flush, Accessory drive belt inspection, Power steering fluid flush, Transfer case fluid change (4x4) | Major service interval. Transmission fluid is vital for gas engines; diesel transmissions often have longer intervals. Coolant flush prevents corrosion and maintains cooling efficiency. Inspect accessory belt for wear. |
| 100,000 miles | Spark plugs replacement (gasoline engines), Accessory drive belt replacement, Timing chain inspection, Differential fluid change (front and rear), Transfer case fluid change (4x4) | Crucial for gasoline engines. Spark plugs are a wear item. Inspect the timing chain for stretch (no replacement interval as it's a chain). Consider replacing the accessory belt. |
| 150,000 miles | Transmission fluid and filter service (diesel engines), Coolant flush, Fuel filter replacement (diesel, if not done earlier), PCV valve inspection/replacement (gasoline engines) | Another significant milestone, particularly for diesel powertrains. Transmission fluid change for diesel, if not done at 100k or 120k per specific diesel powertrain recommendations. PCV valve ensures proper crankcase ventilation. |
Routinely maintaining your 2025 Ford F-350 Super Duty according to the factory schedule is paramount to ensuring its legendary reliability and maximizing its lifespan.
