Don't drive around on empty -- or close to empty.
First, the fuel guage isn't always accurate. In fact, it's really just an estimate of how much gas you have left in the tank.
Second, allowing the level of gas in the tank to run low can damage your car.
According to Consumer Reports, the gas in your car "acts like a coolant for the electric fuel-pump motor, so when you run very low, this allows the pump to suck in air, which creates heat and can cause the fuel pump to wear prematurely and potentially fail."
That repair could cost a couple hundred dollars -- more than what it would have cost you to fill up the tank. Also, "if there is dirt in the fuel tank, it could lead to blocking the fuel filter" -- leading to another expensive repair.
