He advised to NEVER buy fuel with ethanol in it and never keep fuel

In Iowa, where they make the ethanol, every vendor offers three grades
of gas, one of which has ethanol. As for keeping fuel more than two
weeks, that is just insane. How long do you think it is in the
pipeline before it sits around the tank farm? The local small town
convenience store sells 100 octane gas during the racing season.
Very expensive it is, low lead 100 avgas is much cheaper.
