    The MINI uses a 50/50 coolant solution compatible with standard Kevlar reinforced EPDM (Ethylene Propylene Diane Monomer) cooling hoses. Do not exceed a 60% ratio of A/F - Coolant. Comply with water requirements.

    BMW / MINI Anti-Freeze/Coolant contains no nitrates or phosphates and is formulated to prevent excessive silicate drop-out.

    Do not mix BMW Anti-Freeze/Coolant with different antifreezes which contain nitrates or phosphates and a high silicate formulation. Severe engine damage may result by doing so.

    So to answer your question, yes.

    First off, the most important thing to do in a coolant change is to use distilled water (you can flush the system first with regular tap water). The reason European manufacturers specify phosphate free coolant is that most water there has a lot of minerals that will cause deposits in reaction to the phosphates. Toyota also specifies their own brand of "long life coolant" that is phosphate free. Prestone Extended Life 5/150 Antifreeze/Coolant is phosphate, silicate, and borate free. This coolant uses a special chemistry and technology that extends the life of the corrosion inhibitor package so that it lasts for five years or 150,000 miles (whichever comes first), and is safe for all cars and light trucks. Havoline Extended Life Anti-Freeze/Coolant DEX-COOLalso uses a patented organic acid corrosion inhibitor system which eliminates the need for silicates, phosphates, borates, nitrites and amines. Zerex G-05 is also safe for the Mini (yellow) and their website specifically refers to Minis. The idea that you must use "Mini" brand fluids is baseless. Mini does not manufacture these fluids.
