How much oil does a 3.5 Toyota Sienna take?
A 3.5-liter Toyota Sienna takes about 6.0 quarts (5.7 liters) of engine oil when you include a new filter, or about 5.0 quarts (4.7 liters) if you drain and refill without replacing the filter. This figure applies to the 3.5L V6 used in Sienna models through the 2020 model year.
Note that the Sienna lineup shifted after 2020. Beginning with the 2021 model year, the Sienna moved to a hybrid-only configuration built around a 2.5-liter engine, which has a different oil capacity and service procedure. Always consult your owner's manual for the exact specification for your exact year and model.
Oil capacity specifics for the 3.5L V6 (2GR-FE)
Before listing the typical figures, it helps to understand that the exact capacity varies slightly depending on whether you replace the oil filter during the change.
- With oil filter: 6.0 quarts (5.7 liters)
- Without oil filter: 5.0 quarts (4.7 liters)
In practice, use these figures as a starting point. After draining and adding oil, check the dipstick with the engine at its normal operating temperature and adjust to the full mark as needed. If you’re uncertain, aiming toward the 6.0-quart total with a new filter is a safe default.
Model-year context and caveats
From 2004 through 2020, the Sienna relied on the 3.5L V6 (2GR-FE), and the oil capacity above applies to that configuration. The 2021 and newer Sienna models are hybrid-based and use a different 2.5-liter engine with a separate oil capacity specification. Always verify against the exact vehicle manual or a Toyota dealer for your year and trim.
Recommended oil type and grade
For the 3.5L V6, Toyota generally specifies 5W-30 oil that meets API SN/SP and ILSAC GF-5 standards. Some regions or climates may permit 0W-20, but you should follow the exact recommendation in your owner's manual for your vehicle’s year and market.
Summary
The 3.5-liter Sienna V6 typically requires about 6.0 quarts (5.7 liters) of engine oil with a new filter, or around 5.0 quarts (4.7 liters) if you don’t replace the filter. If you’re working on a 2021+ Sienna, note that the engine and capacity differ due to the hybrid system, so always consult the manual for the precise figure. After an oil change, verify the level with the dipstick and adjust as needed using the recommended oil grade.
