Can I use green coolant in my BMW?
BMW only recommends certain coolants because they do not contain nitrites, amines, phosphates, or borates. This new green-colored coolant was introduced in 2018 and is used instead of the older blue-colored coolant. Green is backwards compatible with blue and can be used on cars before 2018.
