Ford Super Duty Oil Change Guide
Oil Types, Capacities & Service Intervals for F-250, F-350 & F-450 Engines
Ford Super Duty Oil Change Specifications
Ford Super Duty trucks — the F-250, F-350, and F-450 — are built for heavy work, and their engines demand proper maintenance to deliver maximum towing capability and durability. The Super Duty lineup offers two engine options with very different oil requirements, and the 6.7L Power Stroke diesel in particular requires specialized service knowledge.
| Engine | Oil Type | Capacity | Filter | Interval |
|---|---|---|---|---|
| 6.8L V8 Gas | SAE 5W-30 Full Synthetic | 7.0 quarts | Motorcraft FL-820S | 7,500 - 10,000 miles |
| 6.7L Power Stroke V8 Turbo Diesel | SAE 15W-40 (CK-4 Diesel-Rated) or 10W-30 Synthetic | 13.0 quarts | Motorcraft FD-4625 | 7,500 - 10,000 miles |
Engine-Specific Oil Details
6.8L V8 Gas
Oil Type: SAE 5W-30 Full Synthetic
Capacity: 7.0 quarts
Recommended Interval: 7,500 - 10,000 miles
New-generation V8 gas engine. Higher oil capacity than the F-150 V8. Full synthetic recommended for protection under heavy towing loads.
6.7L Power Stroke V8 Turbo Diesel
Oil Type: SAE 15W-40 (CK-4 Diesel-Rated) or 10W-30 Synthetic
Capacity: 13.0 quarts
Recommended Interval: 7,500 - 10,000 miles
The Power Stroke uses diesel-specific oil rated CK-4 or CJ-4. Do not use gasoline-engine oil. The 13-quart capacity means oil changes cost more but are essential for injector and turbo longevity. Motorcraft 10W-30 synthetic is the premium option for extreme conditions.
Oil Change Tips for Your Super Duty
- The 6.7L Power Stroke takes 13 quarts of diesel-specific oil — using the wrong oil rating (API SN vs. CK-4) can damage the diesel emissions system
- Super Duty trucks used for daily towing or commercial work should change oil every 5,000-7,500 miles regardless of the oil-life monitor
- Fuel filter changes are just as important as oil changes on the Power Stroke — Ford recommends every 15,000-20,000 miles
- The gas 6.8L V8 shares the same 5W-30 synthetic as most Ford EcoBoost engines, but uses a higher capacity at 7 quarts
- Severe-duty applications (construction, farming, commercial hauling) may require intervals as short as 5,000 miles
