Seems to me the Ethanol issue in BMW engines, requires BMW NA(or any manufacturer who cares), to step up & definitively discuss the issue. Otherwise, the EPA mileage sticker is meaningless & reliability issues will continue with some or all models.
Maybe the vehicles need an Ethanol meter in the dash to warn drivers that the fuel in the tank contains too high a %tage of Ethanol.
