What does ethanol do to small engines?

I've noticed that the ethanol will destroy primer bulbs, fuel lines, and the gaskets inside carbs. What else happens to small engines running ethanol fuel?

The only thing on Echo trimmers and blowers is the primer bulb andgas tank gromet, nothing else. I do believe the use of Red Armour 2stroke oil might make ddifference.

I don't see these issues you folks speak of, maybe a little at first, a few gaskets gave way but it could have just been lack of maintenance, either way my stuff runs pretty flawlessly most of the time (or no worse than any other time).

Actually, cheap 87 octane does that.

I run premium and my stuff is shiny clean.

I can see that it's mostly a farm subsidy that increases the overall price of food in the store, and that it simply diverts the problem rather than solving it, overall I can agree with what you're saying, I don't think it harms engines the way folks tout but that it's a waste of time, we can agree there.

I don't think it actually harms engines but it does harm fuel systems. and it can't be stored for any length of time. in a small engine it can gum up the carb pretty quick if fuel is left un touched over a season.

It is a useless program and actually may not save any "fossil fuel" as I here there is a definite 2% MPG disadvantage with eth gas and the fuel cost associated with growing and creating the ethanol also removes what ever savings we were shooting for.

Stale fuel gumming up the carb is an ages old problem that didn't suddenly start with ethanol fuel. The Varnish (Gum) that is left behind after fuel evaporates is a gasoline issue, not the ethanol. Ethanol is very clean compared to gasoline and leaves very few deposits after it evaporates.

They actually seem cleaner inside, most engines after year 2000 are all made to run on ethanol fuel. As long as its only 10% ethanol and the motor is after 2000, its fine. Some even as far back as 1995. There is a bunch of marketing crap given out by "ethanol treatment" manufactures though. One is that the ethonal holds water, its actually the gas that does. Don't believe everything they say about the ethanol fuel, the ethanol fuel treatment companies will say anything to get you to spend money and buy their product which is mostly alcohol. In some cases that fuel treatment alone can gum up the carb. Ive seen it happen...

Fueltesters and pure-gas have some great info on additives. They break down the main ingredients in each product. Sea Foam, Sta Bil, Starbrite, Lucas, etc and all of them contain some type of alcohol, harsh solvent or even ethanol.

I used to be one of the guys that would put Stabil and Sea Foam into every gas can. I did not do any research and was being stupid. Gas companies spend millions in research and add their own additives to the fuel. If there was something so amazing on the market, the gas companies would already put it in the fuel.

Absolutely incorrect. Water mixes with ethanol (and other alcohol), but will not mix with gas. How do you think water stays in solution in isopropyl alcohol? Have you ever seen water separate out from non-ethanol gas? You can pour the straight gas off the top after the water separates out and run the gas with no problems.

The gentleman who does these tests works for a petrol lab.
He does his own tests on his own time.

How do you get a gallon of 91 octane ethanol gas from the
2nd busiest station in town to be exactly 10%? We've
already found out that isn't going to happen ever.
