Friend and workmate Steve relayed an account of Mike Sizer's Honda Civic ( late model ) which was returning 36-38 mpg HWY,then on trip to Yellowstone National Park and back,achieved up to 44-mpg in the higher elevations.Mikes no slacker ( professional musician and Air Traffic Controller @ Ft.Worth Center ) and I would not discount his claims.He accounts thinner air and ability of electronic fuel injection to compensate,for improvement.
