Blue whale skeleton at New Bedford museum still oozing oil

Ok I'm going to come out and say it because I think multiple people in this thread have hinted at the same confusion: What bloody kind of oil are we talking about here? Whale oil, that somehow was captured in the bones? Petroleum oil from the whale's encounter with the tanker? They basically buried the lede on this story and nowhere appear to explain why this particular whale is dripping some kind of "oil" that seemingly other museum example don't experience. So - anyone got any insight here?

It sounds like it’s whale oil because:

- it’s coming from the bone marrow

- it has a reddish tint

- the curator says the smell is reminiscent of a whaling ship and not, say, a machine shop or oil rig.

I think you are probably right, but then the natural question becomes - why? As in, is there something unique to this specimen and it's display? If I drive over to the aquarium in my state and examine the whale display, would it also drip?
