"Good stuff" ? "Cheap stuff" ? I don't think these apply to different octane ratings of the same fuel.

My 2010 RT with the 998 also saw the same improvement; when running premium...
But my 2014 RT with the triple saw no difference in fuel mileage...

He has worked on cars that have sat for an extended amount of time, both carb and fuel injected. Injectors will crystalize at the injector nozzle and even crystalize in the lifters and seize them. I've seen it personally several times.
Yes newer vehicles will burn it, without problem. Just don't let them sit any long period of time. Ethanol attracts water, only takes 30 days to seperate from the fuel and will settle in the bottom of the tank. Then the pump sucks water first into the fuel system. Do what you want, I don;t want that in any of my vehicles that aren't driven consistently. For me, the ethanol free is cheap insurance or I'm using a stabilizer.
Many people live in areas where non-ethenol is not available and their vehicles still seem to operate. Stop the silliness. Do I use non-ethenol when I can get it? Yes. Is it available within 100 miles of me? No.

Crystallized? Into diamonds possibly? What does fuel have to do with lifters? Come on now this is BOGUS.

Here is a link to all non ethanol gas in the US and Canada. In addition almost all marines have it.

Go back and look at this thread from last fall about my experience with regular vs. premium. Everyone was fooled! The answer to the poll question is the one no one chose!

The requirement to retard ignition (premium gas does just that) is dependant upon elevation. Pure and simple. Anything above 4,000 feet really doesn't warrant premium gas just due to the principles of combustion. Less elevation the requirement is varied ... I would think that at sea level it is the most required.

After 4 tank fulls with the 93 octane I have calculated 28 MPG, a loss of 4 MPG and no noticeable change in power. But a change in cost at the pump to the tune of $0.30 more a gal. So as you can assume I will be going back to 87 octane.
well stated and I agree with you on the 87 octane. I just got my 2018 RTL (my 4th Spyder) and I have run on 87 octane with all of them. Some of our NISR (Nebraska Iowa Spyder Ryders) club members won't go on longer rides if they know there is no 91 octane available along the way??? I also tried the higher octane thing and found no noticeable difference on performance and MPG. enough said...

Sorry but it's not that easy.
First, higher octane does NOT "retard" the ignition.
It suppresses PRE-ignition from high compression. It also helps keep the mixture from exploding instead of burning in a controlled manner.
Regardless of your octane, when the spark hits, the mixture burns.
Then to your elevation claim......that is true but only because the thinner air makes for a richer mixture and a rich mixture isn't as prone to either pre-ignition or spark knock. Other things can cause a richer mixture too.
And other things can, and DO, make higher octane unnecessary, most notably engine design.
