A 6.4 Powerstroke engine typically holds 15 quarts (14.2 liters) of oil with filter change.

The 6.4L Powerstroke diesel engine, found in Ford Super Duty trucks from 2008-2010, requires 15 quarts of engine oil for a complete fill including the oil filter. This capacity is essential for proper lubrication of the high-pressure common rail fuel system and dual turbochargers. Using the correct oil capacity ensures optimal engine performance and longevity.

Important Considerations

Always verify oil level after filling and running the engine. The 6.4 Powerstroke's high-pressure fuel system and EGR cooler can affect oil capacity slightly. Never overfill beyond 15 quarts as this can cause foaming and reduced lubrication effectiveness. Use only API CJ-4 or newer specification diesel engine oil for optimal protection.
