Ethanol kills engines, not just children
Backstory"EPA requires that retail stations that own or operate blender pumps either dispense E15 from a dedicated hose and nozzle if able or, in the case of E15 and E10 being dispensed from the same hose, require that at least four gallons of fuel be purchased to prevent vehicles and engines with smaller fuel tanks from being exposed to gasoline-ethanol blended fuels containing greater than 10 volume percent ethanol."
Read between the lines: E15 is bad for small engines - like in motorcycles. But it's OK by the EPA!!!
