Lexus recommends using the minimum octane rating shown or higher. Lexus warns that the use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, you can damage the engine and that damage might not be covered by your warrant. See this warning at: Lexus
