The car takes care of that by keeping track of when you fuel. It will burn some of the gas to keep it from going bad, to keep the engine oiled, and occasionally to keep the vehicle warm. The gas tank is pretty small (9 gallons), so it's not a big issue and only a tiny amount of fuel is used for these things. I normally keep about a quarter to half a tank in there, which is enough to be more than comfortable but not enough that I'm burning a lot of gas to keep it from going bad. It automatically keeps the average age of gas in the tank from going over 6 months.
