The reason BMW can (and do) specify specific fluids for maintaining your warranty is that they provide them as part of the maintenance program. Otherwise, they'd have to let you use "equivalent products". But not BMW, which is why the service person had to whisper. Personally, I don't think using any major brand of "green" coolant will do a BMW any harm (don't use Dexcool), but BMW has a similar policy with differential fluid, transfer case fluid, transmission fluid... the only exceptions being brake fluid (DOT-4) and motor oil, where they have a list of "special oils" they support.
