My average mileage for the commute to work, for the last 2 weeks was 38.3mpg. My trip home was kinda disappointing. Average MPG for the 350 mile trip was 33.1. I did a little experimenting. Apparently, this car doesn't do well (MPG-Wise) above 65mph. Was getting 36mpg at 65mph, and was getting 30mpg at 75mph. My MazdaSpeed3 got 29-30mpg at 80mph! Maybe the engine needs a little more time to break in. I'm hoping so. At 1700 miles, now.
