The biggest FE gains won't be made with aero-mods unless they are pretty extreme. You can double your EPA estimate by simply driving different. A partial grille block and a front air dam won't change the look of the car but could give you a few more MPG on the freeway. You'll see a big difference sticking to 55 MPH and taking it easy on the surface streets as well. I have a similar longer distance freeway option on my commute but I can get far better mileage by sticking to the streets and timing the lights. But, my commute is only 22 miles round trip, so it doesn't take too long even when topping out at 35 MPH.
