    Yes, since you live in a very cold climate in the winter. Why take a chance? There is about 10-15% ethanol in the 'new' gas but that may not be enough in sub-zero weather.

    Coming from an auto repair shop, we can honestly say we have not seen a gas line freeze up in many (20) years. The gas blends today have a minimum 10% ethanol (alcohol) already added. In Winter, even more is added. That is probably the biggest reason why your gas mileage falls off so much. We would pass on buying gas line antifreeze.
