since I started watching and E85 is around 30% lower price, so even if I lose 10-15% on the MPG, I still come out ahead on the miles per dollar (calculated a 27% increase in miles per dollar at current local prices assuming a 10% loss in MPG).
You are seriously mistaken as to MPG loss. Closer to 20-30% and on the bad end when loaded. It exceeds the price difference.
E10 has 111,836 BTU/gallon while E85 has only 81,800 BTU/gallon. A 27% energy decrease in a gallon of fuel means 27% less power available unless the fuel consumption rate is increased by the same amount.
It almost always comes out costing more to run E85 and you have less available power available for towing.
