Alright guys, I've got some results. The first night, I drove 143 miles and I filled up with the same pumps when I started and when I returned. The conditions for driving were kind of miserable, pouring rain, I had to have lights on, windshield wipers going, strong crosswinds, cold weather, and driving in western PA can be hilly at times. Anyways, I figured I wouldn't get very good results considering the conditions, but I ended with 22.5 MPG!!!! I am VERY impressed that my MPGs improved that much. I am well over the EPA estimate and I'm very happy. I just cant wait to see what it can do in the daylight, with warmer weather and no rain and wind!!
