I was getting about 16 mpg on mixed local roads and 2-lane highways. I'd been keeping it in 4th most of the time for the sound/feel. On the last tank I tried putting it in 6th whenever I could (55mph+) and ended up at about 19mpg. That included some pretty awful traffic jams too.

I've tried resetting the mpg while driving to get real-time measurements (wish it could just provide that in addition to the running average)

In 4th, I get about 16 - 18 mpg on the highway. In 6th, it's as high as 24
