Just putting this out there if anyone is interested. My daily commute is 140 miles round trip and in my auto trans Aveo I have never gotten above 30mpg. At least it has been consistent all the way up to 156000 miles.
Now on the other hand typically my wifes Aveo5 Hatchback only goes from our house to the train station and local markets and she only clocks 20mpg. All about a 3 mile radius.
