This BMW replacement anitfreeze is exactly what came in your vehicle from the factory, and should be used anytime new fluid is required. If service was performed or your vehicle has lost coolant from overheating, replace it with an antifreeze that was specially formulated for your engine.
This fluid keeps your engine coolant passages clear and keeps them from corroding prematurely. If corrosion occurs, it can restrict flow and cause your vehicle to run hotter. Full strength, you dilute this coolant 50/50 to completely refresh your cooling system.
