E85 Price per mile comparison

[ChuckD]

I have been doing some calculations on whether it would be cost effective to make the switch. And if it was better for the enviroment. All calculations were done based on a bone dry 26 gallon tank. 87 octane here is $2.53 per gallon = $65.78 for a fill up. We have been averaging 13 mpg. Therefor we "could" get 338 miles on a tank. That equates into 19.4 cents per mile. E85 is $2.39 per gallon= $62.14 to fill up. Now figuring in a 15% mpg loss (using a 91 oct. tune) that would put me at 11.05 mpg therefor we could get 287.3 miles per tank. That equates to 21.6 cents per mile. 2.2 cents a mile differance. It would take the price of regular to increase to $2.81 per gallon and E85 to remain the same for it to even equal out. So in the more E85 you use in a vehicle the more fuel you will use per mile will emit more CO2 than regualer 87. So a simple minded person like myself can plainly show that the EPA trying to pull wool over people, and they even admit it in their data. http://www.epa.gov/greenvehicles/Det...icle_ID=111289
