UPDATE
Continued to get gas mileage as mentioned in my first comment through the winter. I brought it in for her first check up near the end of March, at 3,800 miles. Still cold outside, as it has been until just a couple weeks ago.
Literally, on the way home from the dealer the MPG began going up. And up. And up. I am now averaging ~38 MPG. Still no 40 but within an acceptable range.
It wasn't the weather. I am getting a little better MPG now that it is warmer but we were hanging in the same temperature range for April and most of May that we were for October and most of November.
and immediate difference after taking it in though.
I still wish I got better MPG, and reading other comments about how people in northern climates are getting 42 MPG makes me think I should realistically expect that.
