For the ones saying where's the fact or what not, I'm going to comment as much as I can.
For those of you who may know, some companies or employers have the right to certain such data/patents/discoveries, until such a time it is public. So without violating that and the rules of this site I can try and comment further.
For the comment that I don't know the facts about E15...
E15 1st came available last summer at a gas station in Kansas. It comes from a blend pump, minimum of 4 gallons are allowed to be purchased.
It is specifically set up that way because the local regulators WANT TO "prevent owners of lawnmowers, chainsaws and other smaller motorized devices from fueling up" in their small engine equipment?
Doesn't that direct quote alone tell you that this fuel is NOT MEANT for your small engine equipment?

I wouldn't throw a bunch of technical terms and such out here. What does it matter how many hours I've been in a lab or study with other people who do this for a living.
The whole point of the post was in the title, test it out yourself. No lab or special equipment needed for the regular pro out here.
Prove it to yourself.
The simplest way to put it is that ethanol is hydrostatic, corrosive, contains less energy than pure gasoline, and lastly just plain bad for your small engine. Go ahead and leave your take full of fuel all winter with ethanol gas, see for yourself.
After 6 pages of trying to derail a post, calling me a newbie or anything else you want, ONLY 1 person actually dumped the fuel out of his saws, and replaced it with NON-Ethanol Fuel.
Later this person posted that a noticeable difference was seen and heard in the saw, and it was tuned after changed after fuel. So making it leaner means the saw needed less fuel and more air hence greater combustion because the straight gas had more energy.
I'm not new to using a chainsaw. I cut enough wood each week to put out 1500 bundles of wood for a small local side business with my cousin.
I have 2 saws.
#1 is a Husqvarna 346xp with 18" bar that I use since 2011 with no issues since day 1.
#2 is a Husqvarna 346xp with 18" bar that is brand new still in the box purchased since it was going to be discontinued and I didn't want to purchase a 550XP until the technology was proven so I bought another 346xp for reserve.
Derail all you want, but demand better fuel. If I put pages and pages of data in a report on this, all backed with the scientific part of data, it would all show its cheaper for the politicians to subsidize the farmers corn by purchasing it and dumping it in the ocean or donating it to a poor country than refining it and putting it in our fuel. But what for? Just prove it for your self with a $5 of non ethanol fuel.
I'm actually in the process of getting a local suppler to bring in non ethanol fuel, because a lot of the guys doing landscape around here spend big money on their equipment in repairs due to the fuel.
And all the repair shops around here are saying its all due to the fuel.
Its going to be made available at a pay at the pump 24 hours for guys in the trades.
The whole point of the post was to get others here to actually do a test for themselves. Why have me prove it to you when your only going to believe it when you can see it anyway? Those would be real word results you could see and not dispute.
