I find if you use the screens
I find if you use the screens on your dash on ECO mode and follow the instructions related to the green and blue lines showing you how to drive economically. You really have to pay close attention to what that dash is telling you to do, if you are able to follow that you can get up to 44 MPG and typically not less than 40 MPG. Of course I'm talking about paved road driving, up and down hills, in town and on highways.
