Why is it E85 instead of E100?

-- Jarhead

I wondered if heat was a problem. I heard burring E85 makes more heat.

Cold weather volatility is a problem otherwise.

Maybe its to keep people for drinking it.

Its just a joke.

Ethanol contains less stored energy than gasoline. And though it does have lower levels of some pollutants, you have to burn MORE of it to go the same distances so the savings are not all that much. Also, it takes more energy to harvest the crop and distill the alcohol than you get from burning it in your car.

Ethanol is only really about the agriculture lobby getting money from the government (in terms of subsidies) and the government forcing people to purchase their product to throw more money that way.

It's pork barrel politics, not science driving this train.

I can't argue that there is some pork involved. Just like Amtrak is pork and the hemp farms were pork. Washington is porking us to death.

Ethanol can be a decent fuel, in engines designed to use it. But, as Sgt. says, the economics are less exciting than the petroleum economics we know and love. (And, yes, the oil industry porks us too.)

Ethanol is not an answer, maybe, but it could be an interim crutch.
