There are notes on the pumps at Chevron, Union76, and Texaco,
that gasoline can contain up to 10% ethanol during the winter.
Oxygenates.  This must be a state or federal requirement.  Will
check Shell in the morning, but expect the same.

I have run hundreds of gallons of Chevron and Texaco mogas
through my plane with no ill effects.  Except some strange
crazing in spots on my plexiglas fuel sight gauges, which could
be due to ethanol?

My plane and fuel tanks are made of Safetypoxy, which is now
sold as EZpoxy.  Supposedly very fuel resistance, but again
unsure of ethanol.  My tanks have not sprung any leaks.

One thing I can tell you for sure: JB Weld is not fuel resistant.
I initially sealed my sump tank with JB Weld.  It started leaking
after a few months.  Resealed it with JB Weld, again, started
leaking.  Got tired of that #$%@.  Then I sealed it with EZpoxy,
no more leaks for over 1.5 years.  This could be a concern for
people who are using JB Weld in their intake manifolds?
