What’s the deal with E15 fuel?
E15 is shorthand for gasoline blended with 15 percent ethanol. The reason it’s a big deal is that ethanol is fairly corrosive to rubber and certain metals, so it can cause damage to vital components. Ethanol also attracts and bonds with water from the air, and that water can separate out inside the tank due to phase separation.
