Before I moved to NH I used E85 exclusively. There was a lot of it in AZ and it definitely helped with performance. I was getting around 20-22 MPG in combined driving compared to 24-26 MPG on gas. I didn't drive a lot so it didn't make much difference to me, I still had to fill up every 2 weeks regardless of what I put in.

 

I just tried it in mine for the first time, and then took a long drive to the casino. (100miles)

I felt no loss in power. I thought it was a bit quicker from the start, especially at first. Then I got used to it, and didn't notice it after a while, or the computer adjusted itself. - I guess? But still say there is no power loss with mine.

Mileage is yet to be tested, I was going to top it off after 100 miles and see what I got, but it still reads full so can't be too bad.

I'm going to go with E85 for a month or so and see what I think. It's 80cents cheaper than Reg - near my house right now.

Goverment is going to subsidize whether I use it or not, So I see no reason to not try it. What's better continue lining pockets of oil companies or subsidize a farmer?

 

First full tank of E85 = 25mpg
I would guess that was 70% highway 30% city.
When I filled - Reg was $3.85, E85 was $3.03
Now it is under $3

Looks so far it is probably same cost or slightly cheaper to burn E85.
It all depends what the price is at the time. E85 prices really vary, saw 3.03, 3.25 and 3.35 all in the same day at different stations. Luckily the cheapest place is near me.

 

I think E85 works better with high compression engines becuase of its higher Octane rating. Almost like diesel, (although not that high) thats wy you get decreased performance and worse fuel milage. I think if a engine was turned to run on E85 only, it would return performace more similar to a gasoline engine.

 

After a couple more tanks, I've come to the conculsion for me E85 costs more to run. To get the same miles I spend about 10% more on fuel.

That first tank must have still had a good share of regular in it. Cause the next 3 tanks, my MPG really tanked. Right down to the 16/22 they say.

My experiment will be finished after this last tank.
