Using Gas Cubby app as well...
I'm averaging 17.93 mpg. High of 25.44 (highway, but I was moving and had a lot of stuff in the car, so I think it could have been better). Low of 14.19 mpg.
I have a 20 mile (one way) commute and 6 miles of it is on the interstate, the other 14 is the most maddening stop/go city driving ever...
Drive safe, y'all!
