No. The ethanol allows water to be dissolved. It won't separate out willingly.

Buy ethanol free gas. Or I've Also used the ethanol treatment additives. Did they help? Maybe.

I have been removing the ethanol from gas with some lab glass I got on ebay. I wish I had a pic. Add colored water to gas & hake well. Let sit over night. Ethanol is 'hygroscopic' which means it's attracted to water & bonds with it. It is heavier than gas & will drop to the bottom of the 2Liter, pear shaped and conical glass with a petcock at the bottom. The food coloring shows where the 'line' is. Simple

After some googling, the Internet says water thing does remove ethanol, but then:

1) strips out other compounds, lowering the octane of the fuel.

2) the resulting "primarily water with some alcohol" mixture has to be disposed of properly since it won't burn. Pollution via dumping is bad, yo. Waste water treatment can't handle it.

There are websites to find ethanol free gas. I'm not googling that for you.

There are ethanol "treatments" to limit the effects of the ethanol in the fuel.

Tell that to the thousands of gummed up carbs that have been cleaned , if they are lucky , or had to have new parts installed or worse case , been destroyed .

I have to clean my bike carbs every so often to keep them copacetic . There's always yellowish residue that's hard to remove involved .

No , I haven't looked into any of those products .

I paid for the gas once . I shouldn't have to reformulate it and end up paying twice .

Nope heck with the alcohol crap completely ruined my leaded gas outboard motor making me sell my boat because replacement parts weren't available at that time by destroying all the rubber parts on fuel pumps and carburetors and ethanol stripped the two cycle oil film off of everything.

I wish I can get gas that’s has no alcohol and where I live it’s at least 10% I hate it,

I wish I could get pure gasoline like some places at Detroit have.

Actually regular leaded 89 octane like they used to have until the 90s is what I’d like because it had upper cylinder lubricant, small engines never seized when you ran it,

ya it was toxic but engines ran so good with it.

You can buy avgas 100LL from any public airport that has it. I run all my 2 stroke peds, bikes, chainsaws, weed wackers on it. I also use it in my pressure washers and generators because it stores longer.

Marine fuel.

Well the ethanol is an octane booster itself. I never thought about disposal but that's another good reason to just run it.

I read a few studies on ethanol that suggest 7-15% ethanol actually makes more power than straight gas. It changes how the gas burns in the cylinder. More than 20% ethanol and you start to lose power due to the lower capacity.

Alcohol is also a oxygenator and thats a plus.

The varnish is from sitting. Just ride more often. :)

Storage and how long it takes to get through a tank would be the only reason to deal with the hassle. Planes and boats tend to sit for a long time so pure gas is more of a necessity.

Varnish is more golden colored . The crap I have to clean from my carbs is definitely due to gasohol . Kind of a baby shit yellowish .

But , you are right , the quicker gasohol gets used , the better . (edited)

I do the same, but use non-ethanol anyway, cheap insurance. I run the stuff in my old truck too, I don't drive it much, and no petcock! :) For mopeds I make a 5 gallon Jerry can of pre-mix at a time. Top off after every other ride or so, easy. The oldest moped I have owned since '98, cleaned the carb when I bought it, not once since, and it is a Hobbit. Empty bowl, starts every spring. They put a petcock on these things for a reason, use it.

What ??? I thought this was a moped forum .

You mean to tell us there's a higher purpose in life than a fast moped ?

What you're suggesting is tantamount to some jack asking us how to fix his Taotao .

No worries . It's all good . ;)

It's my understanding that the ethanol works as a solvent to dissolve varnish not create it. Once you get that residual off as long as you keep running blended gas on a routine basis you shouldn't have that problem. In fact it should stay cleaner. Carb/injector cleaners are basically ethanol.

Pure gas still starts to break down after a month or so. In the summer you should go through a tank faster than that. And around here the Winters are longer than that and you need to use some stabilizer.

If it was at the pump and $0.10/L more I might consider pure gas. But I really don't see the point of paying more for fuel so that it can sit for over a month. For frame tanks like the Tomos there's minimal surface area exposed to air so it's really a non-issue.
