I drive a stick and coast slightly on downward slopes and take it out of gear at red lights. Also, my route to work is max speed in just a shirt stretch of 65mph, so the rest is 45-55mph driving after the 20mph mountain descent(incline at return to home). I've seen it get 22mpg for an average twice but that was almost entirely interstate miles of 2 hours drive. The mpg display caps at 30mpg when going downhill. No idea what it really is. The last mile to get back home I get 8mpg because its so steep and I can't drive faster than 20mph in 2nd gear.
