    Thanks to all for the insights.  I decided on 91 AKI, E0 and have had very good performance and no issues with now 20 hrs flown. Fortunately, I have a Quick Trip that carries this fuel just outside the airfield (KOJC) entrance.

    915iS published minimum octane is 93 and can contain up to 10% ethanol. Premium unleaded at a reputable service station the best fuel. Any octane lower voids your warranty. Carefully examine MOGAS pumps at airports as octane can vary between 87-93. A way to increase octane of low octane MOGAS is to add the appropriate amount of 100LL to make up the difference. Burning 100LL reduces maintenance intervals due to lead. Rotax engines were designed for unleaded fuel. Rotax is positioned to run the newer unleaded aviation fuels to enter market. - Certified Rotax Technician

    The published minimum AKI (the "octane" number used for auto fuel in the US) is actually 91, NOT 93.

    See Operators Manual, Rev 2, Section 2.3.

    93 AKI "mogas" invariably contains ethanol.  91 is generally the highest AKI rating available with no ethanol (assuming no other additives (eg MTBE or TEL)).

    There is no 93 "Octane" mentioned in the Operators Manual.

    As Tyler mentioned the requirement is for AKI 91.
    The other spec mentioned in the manual is for RON 95 fuel.
    Both are equivalent.
