weapons oil

[malachi]

I wasn't sure where to pose this query so I put it here. Sorry if inappropriate.
In all the lists of all the substances needed to make war, I can find no reference to weapons oil. I know how to clean black powder weapons, but what did they use for gun grease...animal fats?
with regards,

Hallo!

In brief and to over generalize...

Period manuals often speak to just "oil." (NUG, that being "sweet oil," [read as olive oil] or sperm whale oil).
