I seem to be in that fuel economy sweet spot right now in Maryland. The engine warms up quickly and I don't need heat or A/C. I topped off my tank on Sunday and had gotten 40.7 MPG (per the car's calculation) after around 300 miles. My normal driving usually yields closer to 39 MPG.

FWIW the car has 6800 miles on it. I haven't heard much about TCH engine break in but I imagine it's probably loosened up a little and helped the mileage.
