I sure don't know how it did it. From Evanston, Wy into southeast Idaho. Only 125 miles on 1.9 gallons with virtually no wind, riding about 65 with only a couple hills. Maybe it was just really good gas at the Sinclair gas station in Evanston. I got gas there a couple years ago with my LT and it got over 70mpg in the same region. I did get 60 one other time on the same trip but that was with a strong tailwind.
