A 7.3 Powerstroke engine typically holds 15 quarts of oil with a filter change.
The 7.3 Powerstroke diesel engine, found in Ford Super Duty trucks from 1994-2003, requires 15 quarts (3.75 gallons) of oil when performing a complete oil change with filter replacement. This substantial capacity is due to the engine's large displacement and heavy-duty design.
