Kia Optima: Fuel RequirementsYour new Kia vehicle must use only unleaded fuel having an octane rating of at least 87.
Your new Kia is designed to obtain maximum performance with UNLEADED FUEL, as well as minimize exhaust emissions and spark plug fouling.

Never add any fuel system cleaning agents to the fuel tank other than what Kia has specified or the equivalent. (Consult an authorized Kia dealer for details.)
