    Normally run 95 - 98 RON here in Oz. 91 RON is at least a 10% Ethanol blend here.

    Best performance and economy is 95 RON @ 4.3 litres/100km hwy (2 up and loaded) and 4.9 litres/100km Urban (solo).
    Wherever you go, there you are.

    I mostly run 91 RON with no ethanol (equivalent to non-ethanol 87 in the US I think)  I tried E10 (10% ethanol in 91 RON, roughly 94 RON) a few times and seemed to get a little less range, but nothing to worry about most times.

    Hi Travelling2bob,

    There is plenty of 91 (87 USA) around that isn't ethanol blended, but getting harder to find.
    Wouldn't touch Shell 98 or ethanol with a barge pole.

    Manual says to use  Anti Knock Index (AKI) octane rating of 87 (R+M)/2 which is the US standard formula you will see called out on pretty much all US pump stations.  This is simply the (RON+MON)/2 or the average of these two values.  Page 70 of the manual (US) speaks to this.  I am using the suggested value (87) with no problems and good mileage (~52), but like cars folks will use higher octane levels in belief it improves performance or keeps the engine cleaner, etc.  Not saying it does or doesn't, just folks do this.
