Too Afraid to Ask

E15 is regular gas mixed with a certain amount of alcohol (ethanol). Because it has more ethanol than normal gas, some cars may get slightly worse mileage.

Technical Definition

E15 is gasoline blended with 15% ethanol. It’s meant to help with fuel supply and emissions goals, but it can affect how efficiently some engines run compared with conventional gasoline.
