E85 was $2.07 a gallon today. 87 octane gas was $2.17 and premium was $2.77.
I was at 110577 miles, last tank was at 110275 miles, for 302 miles on this tank. I filled up with 18.721 gallons, for 16.13 miles per gallon.
I really pushed this tank to the max, the car only has a 19 gallon gas tank! Almost ran it dry.
I saved $14.97 on this tank by using E85 vs. premium, not considering the mileage penalty.
