I just have one question. If ethanol is no big deal for a engine then why does it lower your MPG.
If it as they state "makes your engine run cleaner" wouldn't you get better MPG.
I know car engines have computers that will adjust for the mixture.
All I'm saying is it can't be good if it lowers your MPG.

Think of it as food and calories.
Alcohol has less calories than pure gas. Less calories. Less energy. Less mpgs.

The energy of ethanol relative to gasoline
A. 76,000 = BTU of energy in a gallon of ethanol
B. 116,090 = BTU of energy in a gallon of gasoline
C. .655 = 2/3 = GGE of energy in a gallon of ethanol. A / B. (GGE =energy in a gal. of gas)
D. 1.53 = Gallons of ethanol with the energy of 1 gallon of gasoline. D = B / A.
So the point being ethanol has about 2/3 the BTU's of gasoline so you get less mpg.
If it as they state "makes your engine run cleaner" wouldn't you get better MPG.
The government does't give a hoot about your MPG. Ethanol burns cleaner leaving methane and water. If the gas has 10% ethanol, then that's incrementally less pollutants resulting from gas.

Keeping in mind my motorcycles don't have a rubber diaphragm accelerator pump, and the only rubber parts are O-rings that don't do all that much really, and a O-ring to seal the bowl.
Parked my one bike in 2013, in Aug or so with fresh gas. Started it pretty much just fine sometime the next spring and summer, but didn't drive it. Started it again this year, same old gas, although now one of the idle jets was plugged.
My other bike starts up just fine on anything flammable it seems, although I've only run year old gas in it.
The Jeep Cherokee 4.0 I have will burn anything it seems, and be pretty happy about it. Not sure the oldest gas I've had in it, but 5 years back I was leaving it parked for weeks and I'm sure it had 2 or 3 month gas it in at times.
Point being that in a modern car I (personally) aren't going to worry about gas that's under 6 months old, or even up to a year old. Getting over a year would be time to do something about it, but it's not like we're talking about the old tractor sitting in the back yard that gets fired up to haul wood once every few years, we're talking about cars and stuff we use.
Also keeping in mind that small engines with more rubber parts in their carbs do need additives or else those parts start to go bad.
If the gas has 10% ethanol, then that's incrementally less pollutants resulting from gas.
I believe the first is correct.
I don't think Ethanol leaves methane and water. I'm no chemist, but my recollection of combustion chem is C2H5OH + 3O2 = 3CO2 + 2H2O. No -thanes resultant. I'm not going to bother looking it up.
WRT this discussion about Ethanol in gasoline, I think the third point is highly, significantly debatable. Ethanol typically doesn't sit in the ground ready to be pumped out, refined, and burned in our cars. First, there is the cost of production of the base stock(unless you are gathering sea kelp, or native grass), then the cost of collection of the base, and then the conversion of the base to an Ethanol(ferment, distill), and then the cost of anhydrous storage, transportation, and chemical mixing. By the time this is done, I would say the lifecycle costs to add the Ethanol to the gas, combined with the reduced energy content might be a lot lower than most people think. But - where would ADM and Cargill make their billions off the driving public if it was only a scientific discussion? I mean, leaving it to the scientist isn't much fun for the vote-buying pols now is it?
