E85 is a type of ethanol-blended gasoline that is made up of 85% ethanol and 15% gasoline. It is commonly used as a gasoline alternative in vehicles that have been modified to run on ethanol. Ethanol is an alcohol made from corn or other plant materials and can be blended with gasoline to create a fuel that is less reliant on fossil fuels.

E85 is typically more expensive than regular gasoline, but it can offer some environmental benefits, such as reduced emissions of greenhouse gases. It is also generally less expensive than pure ethanol (E100). However, E85 can have lower energy content than regular gasoline and may not be suitable for use in all vehicles. Some vehicles are specifically designed to run on E85, and these vehicles are often called “flex-fuel” vehicles because they can use either E85 or regular gasoline.

It’s worth noting that E85 is not widely available in all areas, and it may be more difficult to find than regular gasoline. It is also typically only available at fuel stations that have a separate dispenser for E85.
