Oil capacity details
Engine oil capacity depends on whether the filter is included in the change. The Highlander’s 3.5L V6 uses these approximate amounts:
- With oil filter: 6.4 quarts (6.1 liters)

When performing an oil change, it is standard practice to replace the filter and fill to the full-capacity specification, then verify the level with the dipstick and add small amounts as needed.
Practical notes for owners
Always refer to the owner’s manual or a Toyota service bulletin for exact figures, as capacities can vary slightly by oil grade or regional specifications. Use a high-quality engine oil of the recommended viscosity (commonly 0W-20 or 5W-30 depending on climate and market) and ensure proper torque on the drain plug.
