Cool, Thanks! Before DC, I had the SuperMID up to almost 29km/l average for the trip, I was down to just barely 26 by the time I reached home. So if the SuperMID was accurate...I averaged 61 mpg for the entire drive home. Wish my daily commute was highway (with lots of trucks to draft) . Funny, I never thought that I would wish for a bunch of 18 wheelers to be in my way!!!
