I ride a stock 2011 M8 800H.O. with a mininum octane requirement of 91 as per Arctic Cat. Localy here in Salt Lake City we can purchase 91 octane ethanol or 88 octane non ethanol fuel. My question is would it be better to run the 91 octane ethanol with AmsOil holeshot additive or 88 octane non-ethanol with 110 octane race fuel blended in? Does anybody know how much 110 would have to be added to the 88 to make it 91? Thanks for the help I appreciate it :face-icon-small-hap
