naturally, other places where there is ethanol in the gas its made from crop refuse, like stalks of crap, BUT not in th big smart, lobby driven, ohh so good usa,, noo sirreee,, HERE  we take food crop land & divert its use to growing a crop that isnt even the best choice for ethanol production, pay subsidies, & HOW  much fuel & water goes into making that gallon of ethanol & how much of it is taxpayer funded? i just, im sure its just me, but, somehow i suspect that this whole project makes a lot more dollars than sense,,

I'm a firm believer in E0 if you can get it.  The engine was designed to run on gasoline.  

You lose mileage using E anything due to its lower energy content.  It's thinner than gas.  It also burns faster creating a little more engine heat not to mention the waste in producing the ethanol to start with.

According to Cornell University professor of agriculture David Pimentel, producing ethanol actually creates a net energy loss. According to his calculations, producing corn and processing it into 1 gallon (3.7 liters) of ethanol requires 131,000 BTUs of energy; but 1 gallon of ethanol contains only 77,000 BTUs [source: Health and Energy]

Corn, as well as ethanol fuel production are federally subsidised.
Using corn as a fuel drives up food prices.  UN has asked US to stop using corn for ethanol because of world food situation.

You know alcohol attracts water. (rusty tank problems. Stabilizers fix this) Alcohol dissolves plastics and rubbers. (sooner replacement of fuel lines, rubber gaskets and seals. No stabilizer stops this)

All that said, E10 shouild be fine.  I run E10 about half the time. The engine sounds different when I do.  I wouldn't go E15.

Once again

If someone wants to sell - or buy - ethanol "enriched" fuel, they should be able to do so. But I think the pump should be labelled with what is actually being dispensed, not a generic label like "May contain up to 10% ethanol." I also think the time has come to end Federal or State subsidies for ethanol used in fuel. It has been around for at least thirty years, and if it cannot support itself by now it should be allowed to fail on its own merits.

Matter of fact, here in Nebraska most stations DO have straight gasoline and E-10 side by side. The E-10 typically is labeled 89 octane; the straight gas 87 octane. The straight gas sells for about ten cents more per gallon, probably because of subsidies at some level. Simply because of the price differential the E-10 outsells straight gas.

Bear in mind Nebraska grows a LOT of corn and has quite a few ethanol plants. Also bear in mind some of those plants have closed because the economics of high corn prices make it difficult to realize a profit, unless the plant can sell the residue of ethanol production as cattle feed and also sell corn oil. Even with subsidies it seems the economics of ethanol production might be "iffy."

I don't recall ever seeing a gas pump around here that doesn't have the "may contain up to 10% ethanol" sticker on it so I did a web search for stations in Rochester that sell pure gas. Found four, but two of them are marinas. The other two supposedly still sell 91 octane non ethanol fuel for 4.29 a gallon. At least they did about a year ago - that's how old the most recent updates are.

One of them isn't to far from home so next time I'm in the vicinity I'll swing in and see for myself. I'm actually kinda suprised I found any.
Can't buy decent paint, mosquito repellant(no more than 25%DEET allowed) or lead wheel weights here any more. Silly of me to think I might actually be able to buy real gasoline.
