A 46 cent difference only 16 miles away from GetGo

I stopped at the Sunoco Station on the Pa. Turnpike today on my way to the Nordic Ski area. What a surprise, E85 was $2.31 while unleaded was $2.77. My Ford dash indicated a 29.0 mpg average when I pulled in. I promptly added .43 gallons of E85 ($1.00 worth) to 1.65 gallons of unleaded (around a 25% ethanol blend). 42 miles later at the bottom of the Mountains, my Ford Dash again read 29.0 mpg. The mileage then dropped driving up the mountains where a 10 degreee difference existed in temperature. By the way, the ski area has received 100 inches of snow this month!
