Di-icing fluid is liquid gold and costs more than fuel I believe and wings stab and fin on a twin A or B takes between 250 - 500, depending on the level of contamination and that is just for ice. Clearing the airframe of snow drives the usage up and I hear a middle eastern B big twin took over 30K L recently.
However, this is off of a mobile rig at a base that is not really geared up for adverse conditions.
