Too Afraid to Ask

E85 is a fuel with a lot more ethanol than regular gas. Only certain cars can use it safely, and it may not go as far because it has less energy per gallon.

E85 is a higher-ethanol fuel blend (commonly 85% ethanol and 15% gasoline) that’s usually only intended for flex-fuel vehicles. The segment notes it’s often cheaper per gallon, but it can come with tradeoffs like energy content and compatibility.
