Bio ethanol fuel is a renewable, eco-friendly fuel made by fermenting and distilling crops such as corn, sugarcane, or other plant material. It can be used in place of gasoline to power vehicles and equipment, and is typically blended with gasoline to create a fuel that is up to 15% ethanol (known as E15). Bio ethanol is considered a clean-burning fuel because it produces fewer greenhouse gas emissions than gasoline, and it also has a higher octane rating, which can improve engine performance. Additionally, because bio ethanol is made from plant material, it is considered a sustainable fuel source, as new crops can be grown to replace those used for fuel production.
