ABSOLUTELY DO NOT USE THE "GREEN STUFF"!!!! It is OLD TECHNOLOGY and contains disolved solids which coat the inside of the coolant system compromising heat transfer AND erode the water pump seals.
Use only the BMW coolant (blue if memory serves me correctly) or the ORANGE DEXCOOL coolant which uses organic chemistry to prevent corrosion without coating the inside of the coolant system thereby enhancing heat transfer; and because there are no disolved solids the water pump seals have a much longer life.
If you top off the coolant with the "green stuff" you will only dumb the blue or orange stuff down!!
