Ethanol in gasoline was given to us by conservative lawmakers to appease the farmers. "Liberal climate freaks" were against it. Look it up.

So, did it ever taste good???
Do you recommend beef or chicken with good gasoline?

On a side note, it's pretty hard to light gasoline with a cigarette. Harder than most folks think. But it is possible, and if you do, WOOOOF!!!

I haven't read the thread other than seeing the "everyone knows gas lasts 30 days, even with stabilizers" thing - 
- so here is a real, large scale datapoint:
Out in the boonies with regular storm power outages, I have 100+ gallons of 9-10 year old summer premium pump gas double-dosed with PRI-G, stored in perfectly sealing metal cans.
Lately I've been making an effort to finally refresh that supply. That gas looks and smells fine. Half of it has already been run in small engines and in a variety of older port-injected non-turbo vehicles. Engine performance is indistinguishable from fresh gas.

I keep hearing peple say this. Maybe I am lucky. Put the zero turn away in the fall. Has E10 in it. Hit it with stabil. Fired right up this last weekend to mow for the first time.
Snowblower is also 4 stroke engine. The fule in there is NOT stabilized. It is well more than 30 days old. Started on the first pull. Because that fule is not stabilized I let it run dry for summer storage.
This is my yearly routine and I have never had a problem. Oh and the generator has stabilized fule in it that is around a year old and it fired up. I need to either run that out or syphon it and use it up.

i use premix. its easy, i only use a gallon or 2 maybe per year. I also use ethanol free and it lasts quite a long time. hopped on the mower a week ago and fired right up with last seasons gas.
Do an internet search for Ethanol Gas Shelf Life. It's a thing. Ethanol gas is a new animal. It's hydrophilic and more corrosive.

^ both are worth reading but also worth fact-checking
You'll see MANY articles recommending to use within 3-6 months. The ethanol absorbs moisture, which seems to form a whit gooey mess that clogs small orifices (idle and operating ports, the tiny mesh screens on filters, etc).
My father showed me the fuel pump/filter/gauge sending unit out of a car that sat for a few years. It looked like he dipped it in resin. It congealed so thick that the components inside were unrecognizable. I've heard anecdotal tales from MANY old timers who said that ever since ethanol came around, their small engine carbs started needing to be cleaned out every other season, but ran fine for years before. The insist something changed.
I'm fortunate to have a few stations nearby that pump ethanol free. I use it in my boat, mowers, chainsaws, etc that don't use a lot but sit for long periods. It's pricey gas but a small price to pay for the dependability.

Gas was going stale and forming gum before they started adding ethanol (or MTBE for that matter). Back in the day I cleaned out a lot of gummed up carbs from motorcycles that had been sitting with gas in them.
Corrosion isn't much of a problem with modern fuel systems (since the '90s) and rubber fuel system components since then are ethanol resistant too.
The one situation ethanol can cause problems is with phase separation. That's where you get water in the tank, it combines with the ethanol and then the ethanol/water separates from the gas. That stuff won't burn. But you need enough water in the gas to make a significant layer and the separation mostly happens at lower temps.
E10 really needs to be stored in sealed containers. That keeps water out and keeps the volatile ethanol from evaporating and lowering the octane rating.

I had carb/gas line problems EVERY single year, until I quit buying fuel with ethanol in it!
The "science" is, I QUIT using E10 in my small gas engines and the problems quit too!
That's good enough science for me!!

I believe MythBusters did a study - based on old movie scenes of someone tossing a cigarette into a spilt pool of gas.
Caveat - don’t try at home!

Two chainsaws, a weedwacker, a stick edger, and a leaf blower. I put both chainsaws away with ethanol fuel in them for probably 5 years. Both of them got fully rebuilt and now get engineered fuel because they do not get regular use. The weedwacker, edger, and leaf blower don't ever sit long enough for ethanol fuel to be a problem. The stick edger and leaf blower are tools I inherited from my father, who is a cheapskate. The leaf blower says no ethanol and of course my dad used ethanol fuel in it, the fuel line in the tank was melted, the gasket around the fuel cap evaporated, the primer bulb was destroyed...I replaced all of those bits with ethanol rated parts and it runs amazingly well.

My 2 cents:
For my 2 strokes, 2 Sthil saws (one over 20yrs old), Stihl backpack blower (20+ yrs), Stihl weedwacker, I use high test in 2 gallon cans and mix in the 2 stroke oil at the pump. I've had it work fine for over 6 months but if it's old I put it in the jeep.
For my gennie I put in minimal gas with long term dose of Stabil. My summer car goes in the garage (with whatever amount high test is in the tank) at first snow and stays there until snow's gone. I've had it 20 years and it starts fine (first 2021 drive was two days ago).
The Quad and ZTM go thru enough to never have gas older than a month. I also have a 20+ year old Toro self propelled that never had Stabil but was usually run dry at the end of the season. The Honda 5hp on the log splitter has also been with me since the mid-late 90s and runs fine with the same treatment.

Where I live we can get 90REC fuel at some gas stations. I use the 90REC to mix fuel for all my 2 cycle engines. For 4 cycle engines I use standard 87 ethanol blend. For seasonal 4 cycle equipment (ie. lawn mower) I will run 93REC and Stabil before I put the equipment in storage until next season. I think Stabil or anything like it helps to lube the valve guides so they won't get stuck while sitting for a long time. I also sometimes just drain all the gas out of the tank and carburetor. If the 87 ethanol blend stays in a carb long enough it leaves a brown crust and can stop up small passages.
