From my calcs. 1 Aussie litre = 0.264 US Gallons
therefor 3.78 Aussie litres = 1 US Gallon
so, we in Qld Australia are paying approx $AU1.20 / litre, the equivalnt is $US3.28 per US Gallon.
Most of our unleaded fuel is 90 RON or better. "Better" is called "premium" and you pay a few cents more for it.
Incidentally, our unleaded fuel makes it really hard to tune our bikes by the spark plug method. I de-snorked and cut chunks out of my air box, and with the rejetting I did, I found that taking the plug out to "read" it was a waste of time. It never changes in colour even if way rich!
YEARS ago when I put a Holly carb on my 253 V8 (YES, I know...that's not a V8! more like a lawn mower engine in America!!) I used the spark plugs as a tuning guide because we had leaded fuel.
