Why should I keep my fuel tank full?
By keeping your tank more full, there is less space in the tank for the fuel to absorb water from, which means there’s less of a chance of freezing. Corrosion is still a factor and can be caused from excess moisture. It takes time, but it does happen. Again, keeping your tank closer to full helps preclude this issue.
