Your fuel gauge tells you which side your gas tank is on. If you’re driving a rental or other new-to-you car, you may not know which side to fill up on. In newer models, car makers have begun to include a “secret triangle” to show you just that. Next time you hop in the car, look on your car’s fuel indicator for this small arrow beside the gas pump icon. This is an easy way to show drivers which side to pull up to the pump.
