The production of E-85 fuel is only 20% efficient. This means it takes the equivalent energy of 8 gallons of fuel to obtain 10 gallons for a net gain of 2 gallons. When 85% ethanol is put in your vehicle it will typically get 35% less fuel mileage so there goes the 2 gallons gained. To top it off it takes 420 bushels of corn to produce those two gallons which if turned into food would feed one person in a third world country for a year. So fill up with E85. raise the cost of everything related to corn and beans (bean production is down to make more room to grow corn). And while you’re pumping that gas count the number of hungry people that will go without for a year.
