This might be a stupid question to those in the know but I have not done much work with heating oil so I thought I better ask first. A friend of mine who is a builder (lets just say he acquired) heating oil on a job he was doing. His oil tank is full at the moment so he is storing the oil in sealed containers until he needs it. He asked me about the oil needing to breathe as like all tanks his has a breather inlet but I told him that was just to allow air in as the oil leaves to go to the boiler so the tank does not compress. Is this correct or will his containers need breathers on them as I was not sure if the oil expands and retracts with the heat etc and I don’t want to be the cause of any misfortune due my misinformation.
