I took it upon myself to increase my good stewardship of our nation's resources by attempting to become somewhat of a hypermiler. My commute is around 47 miles one way and, in the past, I have had to refuel about every 2.5 days. I stopped using my air conditioner and rolled down the windows and now refuel every 4 days. Various of my friends and family have asked me what my actual gas mileage is and I haven't had an answer so with my last fillup (previous to this morning's) I undertook finding out. At my fillup this morning I got 9.1 gallons of gas and had traveled 387.6 miles on that, which equates to about 42.5 miles per gallon and I rounded up to 43 miles per gallon.
Not bad for my little Kia Rio. The old saw about the drag created by traveling with rolled down windows is my next experiment. With this tank of gas I will leave the windows rolled up and use the A/C when necessary. I didn't this morning because it is in the upper 60's and it feels really nice with the cool air blowing through windows. I will keep you informed.
Not that too many people are interested but when has that ever stopped me? :)
