George,

I don't doubt that there is some moisture in heating oil. Even if there
isn't moisture will still get into the tank. In cars there are products
known as Dry Gas that will solubilize and remove this water in the gas tank.
Doesn't the heating industry have something like this?

Yes, and it is also available in jet fuel (kerosene) for the same reason.
