Yesterday I heard some clanging outside while I was working in my basement. Once I heard the vibrations coming through the fill pipe for the oil tank I figured it out. The whistle vent started up and abruptly stopped after about two minutes. Later found the document below in the door. My last fill was in February of 2010, so this represents oil usage for the remainder of that February, March, a week or two in April, and then about half of October, and all of November and December. All in all I think it represents about 103 heating days.
