660 Miles On My First Tank

I got 660 miles on 10.8 gallons of regular 87 octane gasoline. This was my first tank after the 'dealer tank' and I got 61 MPG. I accomplished this by learning how to use the lean burn mode and EV glide modes of the hybrid. I also have a Scanguage. I drive 25 miles to work on a mix of highways and city/neighborhood streets. I use a very light touch on the pedal and look ahead to anticipate lights, stop signs, traffic etc.
