Is E85 worth it in Illinois?

E85 is usually 15–30% cheaper per gallon than regular gas, but ethanol carries ~27% less energy, so the honest test is cost per mile — E85 wins when it's priced at least 20–25% below regular. E85 App compares that for you automatically. (More: is E85 actually cheaper?)

One thing to know about Illinois E85

Pump "E85" isn't a fixed 85% ethanol — it's legally 51–83% and drops in winter. That matters for your octane and for blending to E30/E50. E85 App color-codes stations by their real measured ethanol content so you know what you're actually getting. (More: your E85 isn't 85%.)

Only flex-fuel vehicles (FFVs) should run E85 — confirm compatibility before you fill. See how to find E85 near you or browse other states.
