Lets save the research time and effort. Buy 1 gallon of BMW concentrated antifreeze and a gallon of distilled water. Mixed them together to make 2 gallons of read-to-use antifreeze. Cost about $26, so $13/gallon. Same price as other pre-mix antifreeze from auto part stores. Why not use the legitimate one that is made for bimmers?
