You don't need to be an auto mechanic to know that freezing temperatures and cars aren't always the best of friends. But when it comes to battling winter weather, it's easy to forget that it's our cars that that are out there on the front lines while we're inside drinking hot chocolate and binge-watching Netflix.

Unfortunately, keeping your vehicle happy and healthy during this year's record-setting winter is going to require more than a brush for your windshield—and you have science to thank for that.

Fluctuations in temperature can cause condensation to form inside your gas tank. And the thing about water is that it freezes. Because fuel lines in cars are thin, any moisture in them when temperatures plummet can cause blockages of ice that stop fuel from flowing. Unlike water, gasoline will remain liquid in most subzero temperatures. So, a tank full of gas hopefully means a tank without ice.

So, to avoid engine trouble this winter, the general rule of thumb is to keep your car's gas tank at least half-full when temperatures dip below freezing. Oh, and don't forget your Tupperware!
