Ford F-350 Oil Change Guide
Oil Types, Capacities & Service Intervals for the F-350
Ford F-350 Oil Change Specifications
The Ford F-350 is built for maximum towing capacity, heavy commercial work, and serious fifth-wheel/gooseneck applications, and is available in single rear wheel (SRW) and dual rear wheel (DRW) configurations. The F-350 offers the highest conventional and fifth-wheel tow ratings in the Super Duty lineup for non-chassis-cab applications. With towing capacity of up to 40,000 lbs (fifth-wheel/gooseneck) and payload capacity of up to 7,850 lbs, maintaining a strict oil change schedule is essential to engine longevity under heavy loads.
| 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
The gas V8 option for the F-350. Higher oil capacity than the F-150 V8. Full synthetic recommended for protection under heavy towing loads. Shares the same 5W-30 spec as most Ford EcoBoost engines.
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 higher oil change costs but proper maintenance is essential for injector and turbo longevity. Motorcraft 10W-30 synthetic is the premium option for extreme conditions.
Oil Change Tips for Your F-350
- The 6.7L Power Stroke takes 13 quarts of diesel-specific oil — using gasoline-engine oil (API SN) instead of diesel-rated (CK-4) can damage the emissions system
- The gas 6.8L V8 uses 5W-30 synthetic at 7 quarts — significantly different from the diesel's requirements
- F-350 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
- Severe-duty applications (construction, farming, commercial hauling) may require intervals as short as 5,000 miles
