Will have to see if there are any other studies that have been done. I hate to base everything on one study. If your trying to make things look better then it is, it'* far to easy to fudge the numbers.
As recently as 2007 the Environmental Protection Agency stated on its website that several of the most current American FFVs were still losing 25-30% fuel efficiency when running on E85.
To achieve any short-term operational fuel cost savings, the price of E85 should therefore be 30% or more below the price of gasoline to equalize short term fuel costs for most older pre-2003 FFVs for both winter and summer blends of E85. Life-cycle costs over the life of the FFV engine are theoretically lower for E85, as ethanol is a cooler and cleaner burning fuel than gasoline. Provided that one takes a longterm life-cycle operating cost view, a continuous price discount of only 20% to 25% below the cost of gasoline is probably about the break-even point in terms of vehicle life-cycle operating costs for operating most FFVs on E85 exclusively

1997,1998,2000,2005 year confused Bonneville SSExi. Stock? ish.
It also assumes the prices of gas, and E85 does not close the gap, or even reverse. I looked in to converting my Bonneville over to E85 for the higher rating. But it wasn't cost effective, as well as Sheboygan county has only 3 stations that sell it. So going way out of my way to get it was also figured in. In the end, I was not able to recoup the investment, so the idea was scrapped.
