premium fuel is unleaded fuel but...The RSX-S needs the Premium because it runs very high compression and needs the clean burning premium 91+ fuel. on top of the running advantage premium will get you better MPG and it creates less carbon build-up on top of the valves. In short it will allow your motor to run better, stronger, and longer.
