Honestly -- it'll probably run better and get better mileage with regular. Higher-octane merely delays ignition until later in the compression stroke eliminating knocking in high-compression engines. In the case of these engines, that's not as efficient. Lower-octane fuels are what they call for... AND cheaper.
