You mentioned 70mph on the freeway. Is most of your driving on the freeway at that speed? The reason I mention this is aerodynamics plays a role in mpg also. For instance, I recently took a trip to the GA Dome with mostly 4 lane state highway and interstate driving between 65 mph and 80 mph the majority of the time. I averaged 17.5 mpg according to the dash indicator (it was 17 mpg hand calculated) on this seven hour round trip. Yesterday, the family and I went to the beach and most of the driving was on two lane state highways and it was all I could do to run the posted speed limit, which was mostly 45 and 55 mph because of traffic conditions. My dash indicator read 20.5 on this round trip of five hours. Both trips were very similar in that traffic was moderate and I didn't get stuck in any bumper to bumper, stop and go BS. Only difference was the speed.
