With the one liter on-board tank, I get 1.25 hours at around 5 MPH ( I got the GPS set on MPH rather thank Knots) so I get just over 6 miles on a tank with 3.8 tanks peer gallon. Probably a little more if I slowed it down a little. I bought 3 gallons this year and uses one of them on the famous BEER cruise with the trailer sailors. so 28 MPG is probably right. I vote for the Hohda. its air-cooled (no flushiing in water tanks) and weighs 28 lbs ( I keep it in the shed at home to keep it from being stolen) so its easy to carry and mount. No water pump of shifter to fail. ALWAYS starts. Don in Mobile ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour
