Worst fully loaded with 300lbs of gear, my 200 pound self, and maybe a 150 lb passenger was 17 mpg in a moderate head wind.
I'm about 3800 miles in and average about 24mpg in mixed driving.
What I've noticed is that each start up subtracts 0.1 mpg from the average. Takes me just a few second to put it in gear and get out of the garage. But it does the same thing if I'm in a parking lot.
