It is always a good habit to keep your gas tank full not just so that you always have enough gas, but so that you can avoid other problems that can occur when you get air in your tank. Air is not the culprit, but rather the condensation that air holds. That condensation can cause your fuel lines to freeze and that can cause some major problems.
Come visit us here at Piazza Honda of Springfield so that we can get out vehicle all winterized and ready for the colder months. We will make sure that your vehicle will be able to survive the winter with minimal effort or problems.
So, keep your gas tank full to keep those fuel lines from freezing. Plus, you will be using more fuel to warm up your car and it doesn't hurt to keep it closer to the full end of your fuel gauge.
