True true. Mr. corn farmer that you quoted is the uninformed one. E10 is a raw deal for everyone except for those in the corn trade at the moment.

 

Elistans quote is by far the BEST in the thread: Ill try to improve:

~there are some questions about if the energy put into growing the corn/harvesting/making ethanol is WORTH the energy output - that is, do we put in more energy (in the form of foreign oil burned) than we get out as energy (ethanol). both sides of the issue accuse each other of using half-datas...I dont know where to stand on this issue at all. (as a mechanical engineering student who is really interested in this topic, the fact that I cant pick a side really speaks wonders to whichever side is bullshitting....they're good at it)

Ethanol has a high octane rating, which allows cars properly tuned for this type of fuel to make ridiculous power without worries about detonation - in our cars, running higher blend ethanol would probably be a bad idea.

The reason why we use foreign oil is simple: it is by far the cheapest source of energy we got. When prices of foreign oil go up, we will switch over to a better alternative. The dirty truth is money > morals.

 

I can think of only one good thing about E10. To run an occasional tank full might be a good thing since water and alcohol mix. Any water that may have accumulated at the bottom of the tank can now mix with the fuel and burn off. Not that this is a good thing but it is probably better than having the fuel pump picking up a large dose of water when running near empty. I want to run pure gasoline though 99% of the time and not have to deal with the 10% stuff continously.

 

Yes we could but isn't where they would be drilling in Alaska in a wildlife zone? So would be screwing up all that as well to get a little more gas.
Also it's good to have a reserve as well, if they drill there now and things go even more sour overseas and we already used up our reserves would not be good.
I'd take a hydrogen powered car though..

 

Well, whether you like ethanol or not, all of the enthusiasm over it certainly seems to be dying out -- insofar as mixtures of it over 10% are concerned. We had an expert on gasoline give a tech presentation on it to a meeting of my local chapter of the Mercedes Benz Club, and he told us that use of E10 actually keeps our injectors and fuel systems cleaner than the old additive.

 

Been running 93 octane E10 for 106,000 miles. My car is still kicking ans she gets better than 30mpg if I let her. Nothing to get riled up about

 

There are Pros and Cons but we are using E10 now.
Do we have to be more careful with gas station selection and water contamination in the fuel? What do we look for?

 

Find a station in your area that seems to sell a lot of gas. Gas (whether E10 or not) tends to collect water the most when it is stored for long in the stations' underground storage tanks. The alcohol content can add to the prob, as alcohol tends to draw and absorb water. So if you buy from a gas station with high product turn-over, your chanced of water contamination go down.

 

It seems to me that it will work two ways. Alcohol will absorb 10% of its volumn. In a tankful of approx 13 gallons which would contain 1.3 gallons of ethanol and this would equate to approxamatly .13 gallons of water as a possibility. This is only the capability of alcohol that is left open to the atmosphere or possibly any condensation that may exist in the tank. If you must pump a fuel that contains ethanol, it will be better if you always fill that tank including the filler neck to the top to reduce the surface area that the atmosphere will occupy in any unused portion of the fuel system.
