I did an east and west run with the windows up and repeated the procedure with all the windows down and the cruise control set to 65 mph (63 on the GPS) for all runs. There was no other traffic on the road during the testing.
I averaged the windows-up runs and got 51.05 mpg.
I averaged the windows-down runs and got 48.05 mpg.
That is almost a 6% difference so I feel pretty good about the ScanGuage current mpg test model.

Yes, that's a great result.
