I think you are referring to spermaceti. That was used ass a special lubricant, and as an oil in the days before petroleum based oils were available.

Butt lube?

Nice typo.

In the same Master and Commander series, Dr. Maturin fell overboard and his timepiece got wet as well. One of the midshipmen retrieved some (they had a specific name for it) oil and displaced the sea water. This was the same oil.

Spermaceti was used as a parting agent when casting metals.

I believe it still has some rare applications, (such as certain parts in the Space Shuttle), since it does not break down like synthetic oils. But I might be mistaken.
