I’d like to do a drain and fill on my sisters 2011 Fusion Sport to get some fresh coolant in the system. This year of Fusion was filled with the Ford or Mazda green coolant. So, what should I do here? I have a gallon of AMAM at the house, I have a gallon of Peak Aisin Green 50/50. I’m assuming the Peak Aisin Green would be closest to a factory fill?
