I just gassed up at Shell here in Richmond, Virginia.
2007 Shadow Aero 750
Gas price = $3.89/gal
Odometer = 128.7 (still on main tank, not on reserve yet).
Gas filled to the bottom of vent tube = 2.57 gal
= = = = = = MATH = = = = = = =
50.07 mpg - combination city/highway driving.
Not too bad, if you ask me!
