How many quarts does a 2018 6.7 powerstroke take?
The engine typically requires about 12 quarts of engine oil for a full oil and filter change, which is roughly 11.4 liters. Some variation can occur depending on whether you replace the filter and the specific service procedure used.
Official specification
Ford’s service guidance for the 2018 6.7L Power Stroke diesel lists the oil capacity in two commonly cited figures:
- Engine oil capacity with filter: 12 quarts (11.4 L)
- Engine oil capacity without filter: 11 quarts (10.4 L)
In practice, most routine oil changes are performed with a new filter, which aligns with the 12-quart figure. Always verify the exact capacity for your particular vehicle configuration if you’re unsure.
Practical guidance for an oil change
When planning an oil change, use the following guidelines to ensure you add the correct amount of oil and avoid overfilling.
- If you replace the oil filter, plan to add 12 quarts of oil as the starting point.
- If you drain and refill but do not replace the filter, you can start with 11 quarts and then top off as needed.
- Use the recommended oil: a high-quality diesel engine oil meeting API CK-4 (or newer) standards, typically Motorcraft SAE 5W-40 for the 6.7L Power Stroke.
- After pouring, run the engine for a few minutes, turn it off, wait a few minutes, then check the dipstick and top off to the full mark if necessary.
- Dispose of used oil and the old filter at an appropriate facility and reset the maintenance reminder if applicable.
Following these steps helps ensure you reach the correct oil level and maintain proper engine lubrication during operation.
Oil type and maintenance notes
For optimal protection, Ford recommends a diesel-grade synthetic oil that meets the CK-4 specification (or newer) and a Motorcraft-branded 5W-40 diesel engine oil is commonly specified for the 6.7L Power Stroke. Always consult your owner’s manual or the dealership for the exact specification required for your vehicle’s engine and regional regulations.
Summary
In short, the 2018 6.7 Power Stroke typically takes 12 quarts of oil with a new filter during an oil change, or 11 quarts if the filter is not replaced. Use the recommended 5W-40 diesel oil meeting CK-4 standards, and verify the level after a brief run and cooling period to ensure an accurate fill.
