Did you know that the use of unleaded gasoline with an octane rating lower than what is listed for your model, year, and vehicle may result in engine knocking. 

 To ensure you are using the right fuel grade, see the chart below for the required minimum octane rating for all 2005 through 2018 Lexus models.

For older models, please see your OWNER'S MANUAL under the Vehicle Specifications section for more information on fuel requirements and recommendations. 

If the octane rating used is less than required, damage to the engine may occur and may void the vehicle warranty.
