In Aus it sounds like we have different ratings for fuels, probably due to the metric / imperial difference. Standard unleaded is normally 89octane, premium is 95octane, and most stations now have a super premium (BP ultimate, Mobile Synergy, Ampol vortex, Shell optimax) that is 98octane!!! BP & Mobile have had best reports, Ampol is good, and the Shell has had bad reports from most shops.

I run mine on BP ultimate 98oct which has had best results for my bike. It has some additive that look after your engine while providing better octane rating. So in theory you don't have to run your engine as hard to get same performance which equals better miles per litre (although I usually run it full twist anyway!).
