Re: Beating the EPA - The Why’s and How to Hypermile Or course, until the more fuel effiecent vehicle comes, I will do what I can with my SIlverado. I know this is nothing to most of yall outthere but I was able to Go from Moore OK to Pearl MS with one tank. This is the 1st time I have ever been able to reach 600miles on one tank. When I made the same trip last year I got 22.1mpg, yesterday I got 23.1mpg. I think what probably allowed me to get the increase mpg was my speed. I kept my speed at 60-65 on the interstate (speed limit 70mph). My wife has also become more tolerable of my efforts, Last year she demanded I go the speed limit, now she lets me drive under. One thing that hurt me, the walmart I usually fill up at in Moore OK just made the switch to 10% EtOH. I bet I could have gotten atleast 23.5 w/o the EtOH. There are several stations in town that still sell the pure stuff, but it is usually 20cents/gal higher.
