E85 was $1.79 a gallon today. 87 octane gas was $2.09 and premium was $2.59.
I was at 110008 miles, last tank was at 109775 miles, for 233 miles on this tank. I filled up with 16.129 gallons, for 14.44 miles per gallon. Little highway miles and lots of AC
I saved $12.92 on this tank by using E85 vs. premium, not considering the mileage penalty.
