What's so bad about ethanol? Sorry, I'm ignorant about this and would like to be educated on. Thanks!
Ehtanol has way less power in it per gallon than actual gasoline. I don't have the exact numbers before me, but for some reason I'm thinking it's 120,000 BTU/gal for actual gas, 105,000 BTU/Gal for 10% ethanol (so pretty much every place now is required to carry at least 10%), and 80,000 BTU/Gal for E85. So less power if you aren't tuned for it (think after market tuner) and less fuel economy than regular gas.
And then you get into the political side, where the government subsidizes ethanol production to make it cheaper than gas (it actually costs much more to produce than actual gas), and that the creation of ethanol takes up more energy then it saves. Also it creates higher food prices too (ethanol takes a huge amount of corn to produce). But it is "a start to alternative fuels" and the people making money off ethanol won't give it up without a fight. And everyone looks at oil companies for being greedy and making a ton of money, while ethanol companies are doing the exact same thing, except wasting more energy and money.
Ethanol also can eat away rubber seals and things like that too!
The advantage of ethanol is that it has an extremely high octane, and thus more power can be made versus 93 Octane gas since timing can be safely advanced with out detonation occurring. Many tuners will tune a performance car to run E85. Since it is also subsidized by the government, it also is much cheaper than gas of the equivalent octane (and cheaper than even 87 octane). That is why many modified cars run E85. Then there are many people say that even though ethanol is very inefficient, it is a start to alternative fuels, and with more research better options may come soon.
Then you get the people who think ethanol is the savior of mankind.
E15 has now been OK'ed for adding into regular pump gas too (so what you and I fill up with now). So it doesn't even get a separate pump to distinguish it from regular gas like E85. Several car companies have come out saying if you used E15, your warranty is void.
