Well, You can take this with a grain of salt because I didn't do it over a period of time but I did my daily fuel check and I went down to 60.5 mpg with my altenater turned off so......I don't think I'm going to continue this test. My results turned out to be 5 to 6 mpg lower than what I would normally get for this same trip. To be honest I didn't think it would make that much of a difference. And with your results bbjsw10 it looks like we're in the same ball park....So that's enough testing for me to be convinced... NEXT STOP.....Throttle cable or Cruise control of some sort....
