    ...is getting harder and harder to find.

    I looked at a few online sources such as : https://www.pure-gas.org/index.jsp?stateprov=AZ
    and if you live in a larger city seems to be a bit easier.

    So I went to a few local stations and asked if they knew what the actual percentage was.
    Dumb-founded looks was the most common response and one guy swore it was zero percent but the pump said "May contain 15% Ethanol"

    Well, How am I supposed to really know?

    Here is a quick test to see if your fuel contains ethanol, and if you are a math-y type you may be able to find the actual percentage.

    http://www.autofuelstc.com/fuel_testing.phtml

    "HOW TO TEST FUEL FOR ETHANOL
    To determine if ethanol is in the gas:


    • On a test tube or olive bottle six or seven inches long, make a permanent line about two inches from the bottom.
    • Fill with water to this line, then fill the tube to the top with gasoline.
    • Cover the tube, agitate it, and let it stand.
    The ethanol and water will mix and separate out together. If the water level appears to have increased, the fuel contains ethanol and should not be used. Ethanol percentages of less than 5% can sometimes give a reading below the line. Therefore, any deviation in the water line indicates the presence of ethanol and should serve as a basis for rejecting the fuel."

    I will test some local stations as soon as locate some appropriate testing tubes, or I may just borrow some of my wife's canning jars.

    You can make your own ethanol free gas from gas that has ethanol by adding the fuel to a container with some in it water. Shake well and let stand. Once it has settled, draw off the gas on top, leaving the ethanol in the water below. Same principal as your test.

    Nope, not paranoia. Awareness.
    By the time it gets to the rack over 500 gallons of water is consumed to produce 1 gallon of ethanol. More sulfur dioxide and carbon are put into the atmosphere producing ethanol for fuel than it saves at the tail pipe. Top soils are eroded. It ruins carburetors and small engines and EFI systems not made for it.
    It doesn't play well with two strokes. All the small engines makers warranties become void if over 10% ethanol fuel is used. Ethanol for gasoline is not profitable. It is subsidized.

    Did you quote the wrong guy? I didn't say one way or the other if it was bad, just a suggestion as to how to get ethanol out of fuel that has it.

    You say it "doesn't play well" with 2 strokes, so could you please tell us why? Crank seals?

    The federal tax credit/subsidy expired in 2011.

    Two stokes oil. Ethanol doesn't always mix well with oil. That left more than a few bare spots on cylinder walls. Ethanol isn't just corrosive it's erosive.

    When one tax "credit" ends look for the rise in "farm" subsidies by some other name for agribusiness elsewhere and then do the math. Ignore the name changes of what it is and follow the money man. Follow the money.

    Ethanol has less energy than gas. Fuel economy goes down five to fifteen percent when you run E-10. It adds cost to fuel that gets you less distance. You burn more to go there. Do the math.

    One thing seal clubbers and earth worshipers can agree on is the only benefit of Ethanol is financial and that's to the Ethanol industry and the people who created it. Follow the money.

    Castor bean based oils like Klotz BeNOL, Blenzall Gold, and Castrol R are all commonly used with alcohol (both methanol and ethanol) race fuels and alcohol/gasoline blends in 2 strokes and have been forever. Not rocket science, just old school racing.

    Look at the pump. Non ethanol gasoline costs more. Ethanol replaced MTBE in gasoline because MTBE is a greater environmental evil. If you remove ethanol from gasoline you will need an alternative. What do you propose?

    That would be tetraethyl lead to be exact, and it is where the old term "Ethyl" came from for high octane fuel.

    MTBE was used in very low levels, but lawmakers were “encouraged “ by ethanol producers to require a fuel oxygenator at 10% ratio, vastly higher than economical for MTBE, but right on the money for ETOH. FOLLOW THE MONEY.

    And now, as this thread heads directly into CSM territory, good day.

    Millions of weed eaters, leaf blowers, chain saws and outboards aint racing and hundreds of thousands of places to buy two stroke oil don't carry two stroke racing oil.

    E30 and a tune for it makes for a 20% increase (268 to 320) in power in my WRX. No reliability issues as well. It has it's place. Bone stock components. Not even an exhaust. Sleeper. :D And it gets 35MPG on the highway @70MPH with the a/c cranked. Ethanol has it's place.

    Like mentioned above smokers don't care for it. Methanol? Now that's another story but impractical for the street.

    In our off road race cars, if we can go 200 miles on e-free gas, we go 130-140 on e-85. Yes, we get 7-10 more HP, on E-85, but our fuel range drops, more gas stops.

    How is the "Tune" different?

    and is it feasible to do on a carbureted dirt bike?

    More boost,more timing,cam timing tweaks and a couple of other tweaks particular to the FA20DIT Subaru. Dirt bike? Nah. The FA20DIT is a turbocharged direct injected engine.

    In my offroad bikes I run VP race fuels U4.4. Leaded oxygenated toxic wonder juice @$15 or so a gallon. You can and should tune your bike for a specific a fuel (Sunoco,Exxon,Shell.ect) as you can and run that fuel all the time. The difference with EFI engines is the ability to sense what's going on with the engine,i.e knocking,heat and mixture through various sensors. You just can't have that kind of real time adapting with a carbureted engine.
