Why does my oil tank whistle?
As the oil driver begins putting oil in your tank, you will hear a whistling sound. As oil flows into the tank, air from the tank gets pushed back out. As the air goes through the vent alarm–located between your tank and vent pipe–it makes a whistling sound. When the whistling stops, the tank is just about full.
