E85 is a type of fuel that contains 51-83% ethanol. Ethanol is distilled from plants like corn and made into an alcohol-based fuel, combined with gas. It is known as a flex fuel or alternative fuel and is reserved for use in vehicles designed for it. These vehicles have forced induction engines with higher compression capabilities than other vehicles; E85 flex fuel can be used in these vehicles as well as regular gas. E85 flex fuel reduces the amount of harmful emissions, like CO2, that are expelled into the environment from the exhaust. The increased use of ethanol in fuel is more sustainable and costs less at the pump then regular fuel. However, the use of E85 flex fuel decreases gas mileage and may require more frequent refills of gas. It is commonly debated whether E85 is less expensive than regular fuel but widely seen as a fuel that is better for the environment.
