I filled up last week, but was negligent about posting.
It was at 105843 miles, the last fillup was at 105619. I filled up with 17.449 gallons of E85 @ $1.799 / gallon. That works out to 12.8 miles per gallon.
Premium was at $2.49 per gallon, for a savings of $12.21 per tank.
I did more local driving this tank, thus the drop in mileage.
