What gas does Lexus is 300 take?

The Lexus IS 300 is designed to run on premium unleaded gasoline, typically 91 octane or higher. This high-performance luxury sedan requires a higher-octane fuel to optimize its engine performance and efficiency.


Fuel Requirements for the Lexus IS 300


The Lexus IS 300 is powered by a 3.5-liter V6 engine that delivers impressive power and acceleration. To ensure this engine runs at its best, Lexus recommends using premium unleaded gasoline with a minimum octane rating of 91.

It's important to always refer to the owner's manual and follow the manufacturer's fuel recommendations to maintain the Lexus IS 300's optimal performance and avoid any potential engine damage.


Benefits of Using Premium Fuel



  • Improved engine performance and power delivery

  • Enhanced fuel efficiency and better gas mileage

  • Reduced risk of engine knocking or pinging
