Mercedes dealers sell (or used to) 40ml vials of windshield washer concentrate "S". You dilute the contents of the small vial with 1 gallon of distilled water for warm temps. They recommend adding the vial to conventional fluid for cold temps. I have a vial around here somewhere that I will look for if you want a part number.
