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?)
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 changes your octane and how you blend to E30/E50. (More: your E85 isn't 85%.)
