Kia Optima: Fuel Requirements
Your 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.
✽ NOTICE
NEVER USE LEADED FUEL. The use of leaded fuel is detrimental to the catalytic converter and will damage the engine control system’s oxygen sensor and affect emission control.
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.)
