Unfortunately, both E85 pumps were occupied this morning, and I had to fill up with straight gas. On the positive side, now I can see what my mileage on gasoline (E10) is.
I was at 107863, last tank was at 107580, for 283 miles on the tank. I filled up with 17.293 gallons, for 16.37 mpg.
E85 cost 2.05 per gallon, E10 gas cost 2.25 per gallon, and premium cost 2.75 per gallon.
