Ford F-550 Oil Change Guide
Oil Types, Capacities & Service Intervals for the F-550
Ford F-550 Oil Change Specifications
The Ford F-550 is a Class 5 commercial truck built for chassis cab applications, heavy commercial upfits, rollback flatbeds, and service bodies. The F-550 is a Class 5 commercial truck designed primarily for chassis cab upfits — flatbeds, service bodies, dump beds, and specialized commercial applications. The F-550 is powered exclusively by the 6.7L Power Stroke turbo diesel, and proper oil changes with the correct diesel-rated oil are critical to maintaining performance under heavy commercial loads.
| Engine | Oil Type | Capacity | Filter | Interval |
|---|---|---|---|---|
| 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
6.7L 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 F-550 is exclusively powered by the 6.7L Power Stroke diesel. 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 critical for injector and turbo longevity under heavy commercial loads. Motorcraft 10W-30 synthetic is the premium option for extreme conditions.
Oil Change Tips for Your F-550
- 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
- F-550 trucks in daily commercial service 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
- Upfit vehicles (flatbeds, service bodies, dump beds) with high idle time degrade oil faster — consider time-based intervals in addition to mileage
- Motorcraft 15W-40 is the standard diesel oil; 10W-30 synthetic is recommended for extreme cold starts and maximum protection
