05 rx1 riding 80mph plus on 60 miles of rail grade got 14.4mpg my best so far 15.4 when I went with the lady and ave. 45 mph. 05 Vector riding ave. speed 45mph in open fields packed snow got 18.2mpg. On my 02 viper I was averaging 11mpg, 99sx700 on same trails got 12.5mpg. Hope this helps. By the way I do ride harder on the rx,viper than the lady does on her vector,sx7 so this may account for a little of the differences.
