I drive an F150 an I have experimented with E85
 
I mostly drive my 99 Ford Ranger FFV PU truck. I would try E85 except the closest station is 35 miles away. Last I checked it was the ONLY station in CA selling E85. That may have changed since then. All I can tell you about Ethanol laced regular is I lose about 2 MPG with E10 that we get forced on us in CA.
 
Let's say we get to 15 billion gallons per year. The very best ratio for Corn Ethanol that I have seen is 1.2 gallons for every gallon of fossil fuel to distill the stuff. So at the very best we will be replacing 2.5 billion gallons of gas. Now take into consideration the less MPG you will gain and it don't leave much to brag about. Unless you are one of the fat cats that are running ADM.
 
In the mean time the price of corn has doubled and the price of tortillas doubles. We have more illegals coming to the USA because they cannot afford the price of corn in Mexico. The Agave farmers have plowed under their crop to grow corn and that leaves us with NO TEQUILA. All to satisfy the greed of a few people in the Midwest.
 
You like a lot of Americans have been mislead into thinking that Ethanol will save us from OPEC. It is just a big LIE.

" E85 is 105 octane and if know anyone who builds engines go and ask what that will do. It means that you can run at least a 12.5:1 compression ratio which gets you half way to diesel compressions. The efficiency gain will about 8% from this. Now reduce the engine displacement because of being able to produce a lot more torque and get another 8% - 10%. Everyone only sees the negative. '
 
Theoretically, you're correct. Practically, can't happen, because the engines must still be able to run regular gas, and couldn't with a 12.5:1 ratio. This is an oft-repeated, false arguement for E85. Even CU mentioned it in their article condemning E85. Can't imagine why.

"You do drive a rice cooker Toyota"
 
Cooking rice, I guess that is a feature I'm not familiar with. Let me check the owners manual........ No, there is nothing in the owners manual about cooking rice. Maybe the people that built the car in Georgetown, Kentucky, USA forgot to put it in.
 
"And I need E85 to 20% less costly than gas and it is a wash."
 
It is not going to be that cheap if corn gets to $7.25 a bushel.

"Record corn prices pushed up by flooding in the Midwest have forced five small to mid-sized U.S. ethanol plants to shut and output of the biofuel could be slowed for months, a Citi research note said on Friday. "

Ethanol plants were built when corn was a lot cheaper. They are not going to last long at $7 a bushel.

A 51 cent tax credit per gallon not .45 paid directly by the good ol taxpayer in addition to the tariff on Brazilian ethanol and it's still not an economically viable substitute.
 
"It may sound green, Patzek says, but that's because many scientists are not looking at the whole picture. According to his research, more fossil energy is used to produce ethanol than the energy contained within it.
 
Patzek's ethanol critique began during a freshman seminar he taught in which he and his students calculated the energy balance of the biofuel. Taking into account the energy required to grow the corn and convert it into ethanol, they determined that burning the biofuel as a gasoline additive actually results in a net energy loss of 65 percent. Later, Patzek says he realized the loss is much more than that even. "

Drop the tariff immediately, it's poor economics and costing the consumer. Better yet, drop the tariff and the .51/gal tax credit and let the market mandate the solution while giving the government one less bill to pay. With 10% of all tax revenues going to simply paying the interest on our 9 trillion dollar national debt. We can't afford no stinkin' subsidies.

Oh the Mexicans are starving! Oh the Americans cant afford food! All because of ethanol. Here is the math. There is 56 lbs of corn in a bushel and lets say corn is $5.60 per bushel. Thats $0.10 per lb. If a box of cereal is 1 lb and the main ingredient is corn (lets say 60%) then there is only $0.06 of corn in a box. So what if corn $7+. Then there is $0.065 of corn in a box of cereal. Yep everyone is starving and cant afford food. Subway has $5 footlongs and McD's has an dollar menu but we cant afford to eat.

Look the $0.51/gal goes where? What? Did you say it goes to the gasoline refiners? Not the ethanol producers! This is blasphemy. Those refiners shouldn't be getting the credit, the ethanol producers should. Lets fix this. What the credit goes away in a couple of years. Cant be!

Well you have a choice of 2 oxygenates to reduce emissions. Its MTBE or Ethanol. Wait a minute, MTBE is a carcinigen and has been found in California ground water. If ethanol was used then it would have just decomposed. Why are there hardly any stations in CA with E85? I dont know. There are 5 ethanol plants in CA. I believe Pacific Ethanol has 5 of them.
 
If you lose 2 mpg I dont know what to say. I only lose 20% with E85 in an F150. My buddy has a GM and only loses 20% also. Maybe you should check with the dealer for calibration updates.

"Well you have a choice of 2 oxygenates to reduce emissions."
 
Thanks for pointing out another government screw-up - mandating oxygenate content because of the very slight, and debateable, pollution impact. A recent study by Stanford, I think, found that overall, emissions are higher with E10. So first we poison some groundwater with MTBE, then wast billions and drive up food prices with ethanol, all for naught.

Soon there will be E85 across the country. Then you can use. Did you know the state of CA has a fleet of Ford Escape Hybrids that are designed for E85 use only for them to study. Then you dont need reg gas. Just like when the country switched to no lead gas. We did it before.
