I had to drive to Dayton, Ohio today. I spent most of the 200 miles driving into a quartering headwind. As I neared Dayton, the was a bong and the left-most part of the instrument panel changed to a Low Fuel Warning. This was apparently triggered when the Miles to E hit 50 miles. I filled with 30 Miles to E for a Full Tank Range of 556 miles. When I turned the car on after filling, there were 551 miles to E.

This is quite encouraging. I will be done with the break-in period of 1000 miles when I next fill the car. I had a significant tailwind on the return trip. Both segments of the trip home showed over 40 mpg. We'll have to wait for the next fill to see the full impact.
