Minnesota will go to 20% after their "studys" come back showing it will do no harm to engines. They always make thier research come back with the findings they want---they all do it. Odds are MN will go to 20% after that. Then they will have another Study to see if 30% is OK---and so on!! Why can`t they leave us alone---the percentage of fuel we burn as a whole doesn`t even put a blip on the radar---so think again, what is their motive.
