11 miles on odometer when I picked it up. Full tank, reset trip meter, and 310 miles in, I'm looking at 66.9 mpg on the display. Interested to see where it lies when I fill/compute, but either way, I'm feeling "eco."
Congratulations - though I think you'll find that prior to your first fill will be very approximate. I've found with my last 3 new cars. I'd fill up now, then check how it's going after another 310 miles.
