Bad for fan nozzles (esp. BMW)

Have the product pure times in the container of my BMW E91 filled to prevent freeze definitely one, because at 200 km drive distance per day would be a disaster. I'd rather pay more lion euros due to the high consumption. And unfortunately, I had once made with other brands the experience that place a proper thin (what should keep to -30 degrees) limp made already at -8 degrees. Therefore, I would rather be on the safe side.

But in pure use comes from the fan nozzles only a trickle. A diluted with water (almost 1: 1) brought little improvement. The scent is pleasant indeed but the product itself is not suitable at least for my fan nozzles, contrary to the product description. So I'm disappointed. Sticking the nozzle would in the longer term for the exchange of that lead and is not acceptable (50 euros each!). The two points there only because it is not frozen at -13 degrees. Have the ADAC product replaced and since there are no more problems.
