Does anyone know for sure if home heating oil companies adjust the volume based on the temperature of the oil pumped at the time of sale? Is it legal for them to adjust when temperatures are below standard? Who monitors when they are above 60 degrees? Ive always wondered. I noticed some companies store their oil in above ground storage and with the cold weather we have in the northeast this week id suspect they'd be taking a substantial hit due to more energy per volume of fuel with the sub 60 degree delivery because of the reduction in volume . Oil is bought and sold wholesale by the pound not by a volume measure. I find it hard to believe that these oil companies will be taking a hit because of this seeing that most of their deliveries are pumping much cooler than 60 degree oil during the winter months. It seems all too easy for any dishonest oil delivery attendant to be able to skim a little oil when they are delivering hundreds of gallons at a time also. If they dont already compensate i am baffled. The technology available could definitely compensate. I still dont understand how they can sell a volume of liquid that is pumped from a tank at the time of sale without compensation either way. Gas pumps arent compensating in the southern states so the drivers are taking a dry pounding in the poop shoot every time they buy fuel. 2-3% over 30 years is a lot of money. Id rather pay $5 a gallon and see gasoline companies make less per gallon than to find out that an overseas profiting company is making extra because the energy available per gallon is less than what they are paying for. Basically stealing since they are buying by weight and selling by volume. Who monitors these things?
