Fluids, capacities & service intervals
A used sixth-gen is new enough that recalls matter more than wear, so start with NHTSA's VIN lookup. Then baseline the fluids owners skip, the axles and transfer case, and check the 2.7's oil level against the dipstick, because Ford's published capacities have been inconsistent.
| ITEM | SPEC / CAPACITY | INTERVAL | NOTES & PARTS |
|---|---|---|---|
| Engine oil & filter | SAE 5W-30 synthetic blend (WSS-M2C961-A1); 0W-30 (WSS-M2C963-A1) for extreme cold · 2.3: 6.2 qt with filter · 2.7: 7 qt listed (≈ 6 qt drain-and-fill per a later Ford bulletin, as reported by owners) | Then per the oil-life monitor: Ford expects 7,500–10,000 mi in normal use, 5,000–7,500 with towing, mountains or off-road, 3,000–5,000 at maximum load; off-road operation schedule says every 5,000 mi or six months. Never more than 1 year or 10,000 mi (2021 owner's manual) | Filters: Motorcraft FL-910-S (2.3) and FL-2062-A (2.7).
