Oil guy only fills tank halfway, says he hears the whistle

The last two times the oil guy has delivered oil, we tell them to fill the tank. When they leave I notice the tank is half full on the gauge. Our HV AC guy on his maintenance call said the float is working normally. In fact I popped the top off the gauge and manually pulled up the float and it rea lly sounds just half full. The HVAC guy says the "whistle" the oil guy hea rs is what makes him stop filling. What else could be wrong here? Can we have the oil guy ignore the "whistle" and keep filling till the pressure se nsor stops it (like a gas station) ?

Based on what happened recently to ours, the whistle normally stops when the oil level reaches the whistle, and there is no more air to create the sound.
Also, I don't think the delivery truck's hose valve has an auto shutoff, like a gas station. Our guy would not put any oil in until the whistle was cleaned (by them at no charge).

filler vent fixed so it works properly. You (likely) will not have any luck convincing the driver to ignore the whistle because if he causes an overflow/leak/mess HE is responsible and could very well loose his job.

The little experience I have with oil.... the whistle means that the tank is sealed. The air has to go out some where. The whistle means that the system is intact. If there was a big hole some where, the air would escape there, and no whistle. The whistle is a GOOD thing.
Well, one man's understanding anyway.
I don't know how they know if it's full. But some one on this usenet list will tell you.

vent line that goes up the side of the house. When filling the tank, the air being displaced by the incoming oil causes it to "whistle". When the oil level reaches the fitting, there is no more air, so no more whistle, so stop pumping.
One trouble is the fitting can, over the years, get gunked up and needs cleaning. Takes about 20 minutes and 2 big pipe wrenches to remove it for cleaning.

Sounds simple enough. No tank, no whistle. How do some delivery guy manage to pump 200 gallons into a basement where the tank has been removed? Maybe they assume it is not working and wait for the auto shut-off.

Who takes out a tank, and leaves the fill pipe, hollow and waiting for a disaster? Cap on the indoor end is a good idea, as also with fill the pipe with Great Stuff, or equivilant. Or remove the fill pipe entirely.

Seems like most every year you hear about one. Owner converts to gas and never notifies the oil company.

I'll admit, I've never seen a headline:

Might been on this list. I remember reading of a driver who was frustrated for a moment by all the cement that was in the fill tube. Took a while to chisel out the cement so he could make his delivery.
Wonder if that one whistled?
