I was curious about Mogas(for aircraft STC'd to run unleaded auto gas), and came across this site that shows where to get Mogas, as well as E-Free gas:
Auto Fuel Locations | Mogas Locations
And here is a link to pure-gas.org for the state of Indiana:
https://www.pure-gas.org/index.jsp?stateprov=IN
It looks like pure-gas.org is kinda like gasbuddy.com, in that the average Joe can add or remove stations that carry E-free gas. And, they have an app for that.
