I am considering putting it in the M Roadster if there are no deleterious effects. comments anyone?? from BavAuto.com: http://www.bavauto.com//assets/product_images/prod/npg .jpg Lifetime coolant! One of the biggest troublemakers in your BMW's cooling system is water. It can be a cause of: water pump cavitation; localized hot spots, boil-overs and vapor pockets; internal corrosion due to the inherent minerals; and oxidation of aluminum and metal. NPG+ coolant from Evans Cooling Systems is an innovative product that takes water out of the equation because it is used at full strength * you never mix it with water. NPG+ has been used in racing for years. It does not boil until 375° F, and it doesn't freeze at -40° F like a 50/50 coolant. As a result, NPG+ eliminates a number of the problems outlined above. Plus, when installed in a properly drained and sealed system, it can remain stable for 500,000 miles * you may never have to change your BMW's coolant again! Please note: You must completely flush the original coolant from the system before using the NPG+ Waterless Coolant
