The only issues I remember with ethanol blend were back in the

it was first available here. Some cars had issues with pinging. Those

first. The
ethanol cleaned up the varnish in the tanks which plugged the filters. A
new filter
fixed that issue.
Ethanol does eliminate the need to use products like Heet in the winter.
I use it in my mowers without problems.

The first time I remember it being prevalent was when I was working in
Indiana in the early '80s. I was driving an '82 Firebird and didn't have
any problems.

This town mandated alcohol blends in the winter to cut pollution. My
highly unscientific observation is I have slightly decreased mileage in
the winter. otoh, I also spend more time warming up the car and driving
with a engine not up normal operating temperature.
