Although Dry Gas is really not needed for vehicles during the winter, I still use quite a bit of the liquid.
I run some alcohol stoves for camping, hunting, fishing and the dry gas is the best to use. I scored on almost 50 bottles of the, "yellow bottle", on clearance at Sears, a couple of years back, on a visit to Florida.
For 40 cents a bottle I cleared the shelf! Still the best fuel for an alcohol stove to cook a pot of coffee or soup in the outdoors in the cold or rainy weather.
