E-85 Gasoline/Ethanol blends. OK for Subaru Turbo?

I agree whole heartedly with what you have written. Having said that, and
having seen what you have to say, it appears that the only way an
alternative will be derives is with the help of subsidies and/or grants from
the government. Otherwise OPEC will just shut them down. I don't like
E-85, won't use it in my own car. At least not in its current form. I
race, I want as many BTU's as I can get from my fuel. E-85 is a poor fuel
(in its current state/formulation.) Now if they could somehow come up with
a new process and/or a new blend then I might look at it in a more serious
manner. I can see where some people would want to go the E85 route however.
In ND the cost of regular unleaded gas is ~2.50/gallon, the cost of E85 is
1.65 at the stations I've seen. So it appears that E85 roughly costs 66% of
what gasoline does. And from the info below E85 has 76.535% of the BTU that
Gasoline does. Theoretically that would mean that gasoline automobiles
would only get approx ~75% (rounded down to an even number, for simplicity
sake) of the gas mileage they'd normally get with regular unleaded. So a
car that gets 20mpg on gasoline would get 15mpg on E85. With regular gas
(from here on called "gas") the miles per dollar is 8 (if 1gallon=$2.50 then
20 miles/gallons is the same as 20miles/2.50dollars...I hate written
formulas, Ithink you know what I mean though). With E85 (using the same
formula) the miles per dollar would be 9 (actually 9.09090909.....)

Now all of this is assuming that vehicles actually use all the BTU's that
their fuel is capable of producing. Its possible that E85 is as much as 85%
to 90% as efficient as its gas counterparts in the amount of used
energy...I'm just speculating, not stating as fact. Also, theoretically,
since E85 is higher octane, the fuel system could actually be set to run
leaner than it does with normal gas which would result in even more in favor
of E85.

You know, its kinda fun taking the side you don't agree with sometimes. I
never really put this much thought into it before now, but its kinda
interesting to try and make the case for the E85 supporters out there.
Makes you see things from their perspective.
