With stock alloys and little tires, I achieved 24 mpg with my Raider, once in 2009. With 33" tires and using 4th gear for flatland freeway travel, Raider returned 22 mpg once in 2008, then blew a heater hose. With 31" tires, most of the time I had between 13 to 18 mpg indicated.

My Mighty Max with a stick and turbo, 31" tires and my new lead foot achieves 14 - 16 mpg in town and 18 on the freeway.

All mileage values corrected for oversize tires, cause I haven't changed the drive gears.
