I ran a tank of e85 once and I did feel a power difference, but my mileage went down at least a 2-3 MPG and for me was not worth it.

 

Ethanol from corn is an ecological disaster. It takes more energy to produce than it makes, and the waste it produces is worse than petroleum. It could be made cheaper but corn farmers would throw a fit. They are the only ones benefitting from it.

 

I remember going down to the one-way when I was a kid and smelling the exhaust from hundreds of ethyl burners and diesels crossing the bridge to another state. It gagged one. That no longer happens. Thru cleaner fuels and better engineering. I suppose the fuel cell is gonna get a bad crash rap too.

 

There is a smart time to run E85 in a flex fuel. When very hot! A dum;ber time is when it isn;t so hot. I have driven about 10,000 miles on E85 pure tanks in extremely hot weather, 100 degrees plus. It returns about the same as my 2003 4.6 did in gas mileage. A lot more torque though.

 

That was the old way of production. About 90% of of ethanol is now dry drilled and produces about 40% more energy than it uses. The studies that were made to show that it used more didn't account for the use of the byproducts and tried to make the claim that land being used for ethanol production was basically taken out of production and tried to count that against it because it was not longer being used for food. This was discredited.

Farmers will be the only ones gaining if people like you refuse to take advantage of it properties that are better than gasoline. For example, it's a clean, cheap race fuel. Why pay over $10/gallon when you can pay $2.75? I personally like being able to fill up my 36 gallon tank for less than $100. It costs me $130-145 to fill with premium.

Edit: Oh I see the problem, you have an ecoboost and are mad you can't take advantage of e85. Trust me, if you could use e85 in the eco they'd be quiet a few in the 12s. Don't be mad because you can't play the game yet, I'm sure your time will come.

 

Ethanol won't ever get the same amount of fuel economy as pump gas 87,91,93 as seen here


E85 requires the use of 40 to 50 percent larger fuel injectors, to compensate for its 40-45 percent increase in fuel demand. The change in stoichiometric AFR from 14.7:1 with gasoline to 9.76:1 with E85 is 66 percent, but the resulting flow needed is only 40 percent greater, due to E85's higher density than gasoline

I don't care what import tuner says. I run about 30% normal and 40% at WOT.

Besides, that article is over 4 years old and quiet a bit has changed in the last 4 years with ethanol.

 

It will never change the fact that it takes 30-40% more fuel to achieve the same result... That will never change. Lighter trucks and 8 speed transmissions may be able to help fuel economy but gas will still be better mpg wise than e85.. I just wanted the paragraph I highlighted.

 

Where I buy it it's about a 28% price difference between 91 and e85. I'm using about 33% more fuel than 91 so there's a minimal difference for the extra protection, power, and cleaning that E85 gives.

 

This is crazy! Didn't mean to start a fire storm...It was a one time deal for me just for fun but prob won't use it anymore mainly because of the costs. Fun to try once in a while but I didn't realize it was such a heated subject..
