Mine is full. The overflow (lower half of upper tank) vents to atmosphere, so it needs to topped up periodically. If the overflow runs dry, the fluid level in the upper half of the tank will start to drop over time. It's an odd design. My guess is that most people don't even no the overflow is there and just assume they're good if there's fluid in the upper part of the tank.
