Alcohol has a much lower freezing point than water yet blends real will. The mixture drives down the temperture of crystalization of the water.

Ethanol is commonly used in winter formulated gas. It makes the engine start quicker. It also CAN drastically lower your mileage, depending on the car you have. Same for the E10 gas (10% ethanol) which does not really lower hydrocarbon emissions when you take into account the fact it lowers your mileage and you have to burn more of it to achieve the same effect. E10 lowers CO2 while raising O1 or Ozone, which is worse for the environment than CO2.
