Default 91 or 93 octane?

All,

Is there a recommendation on gas types? I can get 93 octane here, but it has 10% ethanol in it. I read somewhere that ethanol is bad? Would it be better to use 91 octane?

Thanks all!

91 octane is ok for temp usage only. You will get a low punch and low milage for the 91 octane.
