What octane is best for Aussie Roadster

I would run 91 but all the 91 around here has 10% Ethanol and I just don't trust that stuff ,I run 95 or 98 for piece of mind.
 
91, swap around on a long trip and you'll notice the dif. X 10 if you have mods & re-map.
 
Run 91 octane in mine for years now .. probably since Hellfire (RIP) recommended it come to think of it.
 
91. Pointless running anything else in a stock motor. Mine starts easier, runs better and is quieter than on 95 or 98.

No problems with the Ethanol ? maybe because the rockets are sold as is world wide they may be able to handle the blend of Ethanol and petrol. I will give it a try,
 
Don't think .. in fact I'm sure Richard wasn't saying it's ok to run ethanol blended fuel .. I wouldn't run it in either of my bikes that's for sure.
 
TC's correct. Fortunately I can get whatever grade I want ethanol free. Not the case everywhere though. I never put ethanol in if I can help it and if I have no alternative only ever as much as I need to get to the next servo.
 
Have only ever run 98, just checked the manual and it says 91 (2012 Roadster), might drop back and see what happens, but I am about to put on TOR's and a crossover pipe (getting Nev to tune, de restrict and filters in a couple of weeks), so then may go back to 98
 

I doubt any of those changes will necessitate higher octane fuel but I'd just be running whatever Nev tunes it for. Maybe there's an opportunity for him to do a comparison of different fuel types.
