Refueling in cold weather
To help prevent moisture from forming in the fuel system and the risk of its freezing, use of an antifreeze additive in the fuel tank is recommended during cold weather. Use only additives that are specifically designed for this purpose. When an antifreeze additive is used, its effect lasts longer if the tank is refilled whenever the fuel level reaches half empty.
If your SUBARU is not going to be used for an extended period, it is best to have the fuel tank filled to capacity.
