First Tank MPG

[bkrownd]

I finally decided to put gas in the Yaris for the first time, and it got around 37-38 MPG, depending on when it was filled between 0 to 10 miles, and how full the dealer got it. That's a month of in-town driving 3-6 miles at a time, including some break-in zoomyness, and about 25% highway miles today at 50MPH, plus I drove a very twisty mountain road about 15MPH from 4000-6700 feet elevation with more than a dozen stops on the way up and engine braking all the way back down. With so much uncharacteristically wasteful driving on the first tank, this should be the worst MPG my Yaris ever gets...
