nice job man!!!
what techniques are you using?? P&G?
also, what kind of car? transmission? etc?
keep up the good job, once you get to know you routes better, u will get even better...i used to get 35mpg before hypermiling, first tank, i improved to 45mpg; once i got to know my route, i could get 50mpg w/o even trying, high 50's low 60's...
