Keep tank over 1/2 full in winter?

Yes, it is generally recommended to keep your vehicle's fuel tank at least half full during the winter months for several reasons:

1. Fuel Line Freeze: In cold weather conditions, there's a higher chance of moisture accumulating in your fuel lines. When temperatures drop significantly, this moisture can freeze and cause fuel flow restrictions. Having a half-full tank helps dilute any water present in the fuel and reduces the risk of fuel line freeze-ups.

2. Fuel Pump Protection: Running your vehicle with a low fuel level, especially in freezing temperatures, can strain the fuel pump. The fuel acts as a coolant for the fuel pump, and having enough fuel in the tank helps keep it properly lubricated and prevents overheating.

3. Condensation Reduction: When the fuel tank is near empty, more air is present inside the tank. This increased air volume can lead to condensation, which can mix with the fuel and cause engine performance issues. Keeping the tank at least half full minimizes condensation formation.

4. Better Cold Starts: A low fuel level can make it harder for your vehicle to start in cold temperatures. Having a half-full tank or more ensures there's enough fuel available for the engine to start properly.

5. Emergency Situations: Keeping your fuel tank at least half full provides a buffer in case of unexpected events like sudden weather changes or road closures, allowing you to travel further without worrying about running out of gas.

Following these tips can help prevent fuel-related issues and ensure your vehicle's reliable operation during winter.
