I'm in NW Iowa. Being close to the source helps cut out to many middlemen. Our E0 is $4. If you look at the link, you can see Ohio also has a very good spread, as well as Mn.

You definitely have it better there! I don't know why anyone even sells the stuff here. 3% price break for 10% worse MPG? I don't think so.

If only they could make it out of peanuts or pecans.... :)

I ran E85 for it's performance benefits, and it did its job fairly well. End of story. If my ST was flex fuel, I'd use it now. Its not for everyone. Run it if you want, if not, don't.
Cobb should be able to help you out with that. Your physical setup will run E-85, your current setup just doesn't have the ability to sense ethanol content in the fuel.

You can't switch back and forth like a flex fuel car. You'd have to have separate tunes for it.


Cobb released scalars for the Mazdaspeed world to make a quick solution for running E-85. You can always tune it the hard way with changing your MAF curve to compensate for the difference in the fuels lambda

Is flexfuel somehow incompatible with PZEV? I've noticed that any time I see a Focus that's PZEV, it's NOT E85 capable.

(The question is based on seeing about a dozen PZEV focus cars that are NOT flexfuel, and the only FF I've seen wasn't PZEV.)

Yes, all PZEV MK3 Foci have two catalysts for emissions, as well as it's more difficult to meet the evaporative emissions requirements (i.e. no vapor is allowed to escape for 150,000 miles) for a PZEV model, and due to the fact that Ethanol evaporates more readily than gasoline it is not compatable with the PZEV models.

One thing to remember, E10 does have a higher vapor pressure(evaporates more easily) than the same gasoline portion that is E0 or in it's pure for. However, ethanol in it's pure form has a very low vapor pressure and that's why it doesn't start as easily in cold weather and needs gasoline for help. In cold climates E85 is only 70% ethanol in the winter months. A friend that has done a lot of research says that at about 30 to 40% ethanol in the blend is where it becomes less volatile than pure gasoline.

It gets worse fuel mileage. It seems to be cheaper, but the lower MPG negates that. It's much more corrosive. And it's not like there's an ethanol station at every corner. I doubt too many people will be in the scenario of desperately needing gas and there not being a gas station nearby, but hey, "there's an ethanol station over there".

What is the point of Flex Fuel?
I belive the reason to this is environment concerns and, if you have lived in Brazil, about some years ago, when flex fuel was "invented" in here, ethanol could save a lot of money for you when you have to fill the tank...

I guess it is a way to have competitive alternative to fill the tank. Those who has performance and authonomy concerns, should avoid to have flex fuel cars. They really suck for us...

But, belive me, I hate flex fuel too... Ethanol increases HP (I saw some projects which owner has converted his car to ethanol to have even more HP gain). But in Brazil, in now days, with standard prices policy*, if an ethanol litre costs 70% or more than the gasoline litre price, that's indicates you will be burning money if you fill your tank with that...

*Here, government decides when to increase gasoline price and how much, not the market... but, Petrobras and our government are changing that, so ethanol versus gasoline could be a nice fight for our money again.

So, it's all about to save money (but you are right... much people aren't noticing that corrosion can destroy parts earlier and money saved when they fill the tank with ethanol, just in case it was/is or would the better choice, goes away).

Best regards!

Not sure why we don't use sorghum (not corn) for ethanol in the US

We probably should. Also, you should check the price of corn currently---it's about half of what it was a year ago and probably going lower since everybody is finding better yields than expected. Just rode with my cousin in the combine and the yield monitor was hitting 270 bushels per acre on non irrigated Iowa dirt. My field just did a little over 200 bpa. The genetics keep getting better and better but it takes money for the research which is paying off.

which crisis are you referring too -- peak oil? we're awash in oil. there is no crisis.
