2004 Toyota Prius Oil Capacity

The 2004 Toyota Prius with the 1NZ-FXE engine has an oil capacity of 3.9 qt and uses 5W-30 oil. These figures describe the listed engine for this model year; they are not a universal specification for every Prius year or engine. The capacity is the amount specified for the engine, while 5W-30 identifies the listed oil viscosity.

Use these facts as a reference when checking the vehicle’s oil requirements, and confirm the exact service procedure and any capacity distinction, such as whether the amount includes a filter change, in the owner’s manual. If your engine or trim differs from the one listed, or if the manual gives a different figure, follow the vehicle-specific information. If a needed figure is not listed here, confirm it on the door jamb or in the owner’s manual.
