Chicago and its suburbs have dense E85 availability thanks to Illinois' corn economy — Naperville, Aurora, Joliet, and the city proper all have stations, often well-priced.

Is E85 worth it in Chicago?
E85 is usually 15–30% cheaper per gallon than regular, but ethanol carries ~27% less energy — so the real test is cost per mile (E85 wins when it's ~20–25%+ cheaper than regular). E85 App compares that automatically. (More: is E85 cheaper?)
Know what's really in the pump
Pump "E85" isn't a fixed 85% ethanol — it's legally 51–83% and drops in winter, which matters for octane and for blending to E30/E50. E85 App color-codes Chicago stations by their real measured ethanol content. (More: your E85 isn't 85%.)
