How much oil does a 6.7 Ford f450 take?
The 6.7-liter Power Stroke diesel V8 in the Ford F-450 typically requires 15 quarts (about 14.2 liters) of engine oil when you perform a full oil change with the filter installed. If you’re not changing the filter, you’ll usually refill around 13 quarts. Always verify the exact figure for your model year in the owner's manual or Ford’s service portal, as very small year-to-year differences can occur.
The F-450's heavy-duty engine requires a larger oil capacity than many light-duty pickups. This capacity figure accounts for oil in the sump plus the oil filter, and it’s important to use the right oil to maintain lubrication, fuel efficiency, and emissions compliance.
Oil capacity for the 6.7L Power Stroke in the F-450
The numbers below reflect common factory specifications and standard service practice. If your truck has an aftermarket filter or other oiling-system modifications, the capacity could shift slightly.
The following figures summarize the typical capacity and how it relates to oil changes.
- Oil capacity with filter: 15 quarts (14.2 L).
- Oil capacity without filter: about 13 quarts (without filter).
- Notes: Some model-year changes or aftermarket accessories may cause minor variances (a pint or so).
Conclusion: Use the official capacity as your fill target, and adjust if you know you have not replaced the filter or if your drain procedure differs.
What oil to use and service tips
Ford generally recommends a high-quality full-synthetic diesel engine oil, with viscosity rated 5W-40, for the 6.7L Power Stroke. Always consult your owner’s manual for the current specification and the recommended oil-change interval, as it can vary with driving conditions and model year.
Model-year variations
Across 2011–present, the 6.7L Power Stroke maintains a similar oil capacity, though tiny differences can appear due to changes in filters, oil coolers, or other lubrication-system hardware. If you’ve installed an aftermarket filter or modified the oiling system, verify capacity with the modification documentation or your dealer.
Maintenance steps for an oil change
Before performing an oil change on a 6.7L F-450, ensure you have the right tools and a safe workspace. The steps below outline a standard change with the filter included.
- Warm the engine to operating temperature to help drainage and ensure complete oil removal.
- Place the vehicle on level ground, set the parking brake, and raise the front end as needed to access the drain plug.
- Place an oil pan underneath; remove the drain plug and allow the old oil to drain completely.
- Remove and replace the oil filter with a new one; ensure the filter gasket is lubricated with fresh oil.
- Replace the drain plug, add fresh oil slowly (start with about 12–13 quarts, then check the dipstick and top off to reach 15 quarts with filter), run the engine for a minute, and recheck for leaks.
After completing the change, start the engine and check for leaks; allow it to reach normal operating temperature and recheck the oil level on the dipstick, topping to the full mark if needed. Dispose of used oil and filter properly.
Summary
The Ford F-450 with the 6.7L Power Stroke typically holds 15 quarts (about 14.2 liters) of engine oil when changing the oil with the filter installed. If you don’t replace the filter, expect roughly 13 quarts. Use a high-quality full-synthetic 5W-40 diesel oil and verify the exact capacity for your model year in the owner’s manual. Following proper procedures ensures accurate fill and long engine life.
