I have an '07 Eddie Bauer, EL, 2wd.

Gas mileage really is reflected in driving habits. I only mash the pedal when I need it. (Great engine sound, btw.) But I am averaging 16.5 mpg in mixed driving, and on a 180 mile trip I averaged 19.1 on the highway. I live in SoCal, so that includes driving through hills. When I drive on the highway, I set the cruise control at 70 mph and don't deviate from that unless traffic necessitates.
