Look at it another way...

Dollars per 87 octane (88, 89) gallon whatever you are using divided by your miles per gallon.

- then -

Dollars per e85 gallon divided by your miles per gallon using e85 (2 miles per gallon less than above)

- result -

Your cost of operating your vehicle per mile will be much less using e85 than operating on 87 octane.

Lower your operating expense with a trade off of stopping to fill-up a little more often.
