 Approved for Benz & BMW all years.
 And Porsche/Audi  up to 1996 - they they recommend Zerex Dex-Cool.
 Oh and it is pink  - for what that is worth.
 
 Before I pore it in - looking for advice.

Advice:  Buy the OEM stuff, it is only about $20 a gallon (you will need two to do a complete change) and mix it with distilled water only.
Considering that this OEM stuff is readily available, not all that expensive, I fail to see why people keep trying to use something else..........but, in the end, it is your car and the resulting problems will be yours as well……….
