What is the best gas for Lexus GS 350?

When it comes to fueling your Lexus GS 350, the best gas to use is premium unleaded gasoline. This high-octane fuel is specifically recommended by the manufacturer to ensure optimal performance and efficiency from your luxury sedan.


Why Premium Fuel is Recommended for the Lexus GS 350


The Lexus GS 350 is equipped with a powerful 3.5-liter V6 engine that requires a higher octane fuel to prevent knocking and engine damage. Premium gasoline, with an octane rating of 91 or higher, has a higher resistance to premature ignition, which is crucial for the high-compression engine in the GS 350.


Using a lower-octane fuel, such as regular gasoline, can lead to engine knocking, reduced power, and decreased fuel efficiency. The Lexus GS 350 is designed to perform optimally with premium fuel, and using anything less can negatively impact the vehicle's performance and long-term reliability.


Tips for Fueling Your Lexus GS 350



  • Always use premium unleaded gasoline with an octane rating of 91 or higher.

  • Avoid mixing different grades of fuel, as this can cause engine issues.

  • If you accidentally use a lower-octane fuel, try to fill up with premium as soon as possible to minimize any potential damage.

  • Consider using a fuel additive designed to clean and protect your engine, which can help maintain optimal performance.


By following the manufacturer's recommendation and using premium gasoline, you can ensure your Lexus GS 350 runs at its best, delivering the power, efficiency, and reliability you expect from this luxury sedan.
