Started with about 80 miles already into the tank of gas with an average of about 48 mpg in Virginia. Arrived in NYC with a total average of 55.3. Spent over 20 mins with 4 bars at the max on the graph that shows 5 min mpg because of very slow traffic. That graph looked awesome. My first gas tank bar on the full tank did not move until I had 150 miles, half a tank came at 308. I have about 450 miles with 3 bars still showing. I did my best to get good mpg but this is really my first drive so I am a rank amateur.
