    Around here,upstate NY, I am able to get 91 non etahanol fuel .My 599 seems to run well but I wonder if anyone out there uses an octane booster ? Do they work,any downside etc? Is it worth having some around if you find yourself in a spot with less than ideal octane #'s. Mike

    91 octane with ethanol is not going to bother your 599.

    Standard hi test pump gas in California is 91 octane...

    You won’t have any issues with it...
