# Ethanol-free petrol map

The map below contains information from 2411 stations in MN, WI, SD, ND, and IA indicating that they offer ethanol-free gas. The map data was taken from pure-gas.org, but also relies on latitude and longitude estimates generated from physical addresses via the package tidygeocoder version 1.0.3 as well as geocodio. The “visual dots” are only to be referenced as general vicinity indicators. The physical addresses, however, should be considered to be accurate as per pure-gas.org:

The 5-state pure-gas.org database of stations is also searchable via the following table1:
