I'd like to see +5MPG in my civic, but, I'm not sure that anything is going to change in my case. Even after 8 miles, with only 80 ft-lb of torque max, I know that I'm going to be doing a lot more downshifting. This will probably make the average RPM's go up in the long run. It would be ironic if my FE went down.
