What is in the BMW coolant? Can it be mixed with regular ethyl glycol, like
Prestone or some generic brand? What if you are on the road and need
coolant?
Thanks

Water. If it needs topping up regularly, find the leak and change the
entire coolant.

No, don't mix BMW coolant with anything but water. In the US, BMW
coolant is basically Zerex G48. For best results, you should flush your
cooling system, including draining the block, every 2 years and use
only BMW coolant.
