I consistently get +/- 55mpg, using 91 or 93 octane non-ethanol premium. I'm probably 145 or so in gear, with probably a minimum of 10 lbs of stuff I'm hauling in my three luggage pieces and occasionally on the seat, at any given time. I ride a good mix of city, interstate, and twisties. In the twisties I'm in the 8-9K rpm range, I think. When I was at the Dragon, I got a couple tankfuls that got me 60mpg! Again, non-ethanol when possible. I wonder if the higher elevation made the difference? OTOH, I got a couple of sucky tankfuls in Eastern Missouri on the way there where I only got 49mpg. Granted, I had the luggage packed to the gills, but managed to not need anything on the seat. On the way back from Cincinnati (I had met my family at church camp there), I let my them haul dirty laundry, souvenirs, etc in the Prius so that helped.
