What kind of oil does a Lexus RX400h take?

The Lexus RX400h, a hybrid SUV model, requires the use of 0W-20 synthetic motor oil. This specific oil grade is recommended by the manufacturer to ensure optimal performance and fuel efficiency for this vehicle.


Lexus RX400h Oil Specifications


The Lexus RX400h, introduced in 2005, is a luxury hybrid SUV that combines a gasoline engine with an electric motor. To maintain the vehicle's complex powertrain, Lexus recommends the use of 0W-20 synthetic motor oil. This oil grade provides the necessary lubrication and protection for the engine, while also helping to improve fuel economy.


The 0W-20 oil specification is designed to flow easily at low temperatures, aiding in cold-weather starting and reducing wear on the engine components. Additionally, the synthetic formulation helps to maintain its viscosity and performance characteristics over a longer period, reducing the need for frequent oil changes.


Reasons for the 0W-20 Oil Recommendation



  • Provides optimal lubrication and protection for the Lexus RX400h's hybrid powertrain

  • Helps improve fuel efficiency by reducing engine drag

  • Maintains its viscosity and performance in a wide range of temperatures

  • Reduces the need for frequent oil changes, saving time and money


It's important to follow the manufacturer's recommendations for oil type and change intervals to ensure the longevity and proper operation of the Lexus RX400h. Using the wrong oil or failing to change it as recommended can lead to increased wear, reduced fuel economy, and potential engine damage.
