That's what I've heard PB. Going back to the question about having to use BMW coolant I read that it's Pentafrost NF. Reading the specs on the webpage it is recommended for all BMW models. The coolant is blueish - greenish semitransparent color and is LONGTIME not LIFETIME as Pentafrost SF is, but SF is not recommended for BMW. Why? I have no idea. The only difference according to the specs is that NF has silicates. This acts as a protective layer between the metal and the water to avoid corrosion. Both products do not contain any amines, nitrites or phosphorus. It says that is recommended for non ferrous systems.
