2003 Toyota Prius Oil Capacity

The 2003 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 and oil specification for this model year; they are not a universal figure for every Prius year or engine.

Use the capacity as a reference when planning an oil change, not as a substitute for checking the level. Add oil carefully and check the dipstick according to the owner's manual, since the amount needed can depend on how completely the old oil drains. If you need a figure that is not listed here, confirm it on the door jamb or in the owner's manual.

The facts provided do not give separate capacities for other trims or engines, so do not assume this specification applies beyond the 1NZ-FXE listing. For a different year, engine, or trim, confirm the correct oil type and capacity on the door jamb or in the owner's manual.
