What's 'lard oil'?

If you do a Google search on "lard oil", you'll get lots of hits -
including
http://www.hyperdictionary.com/dictionary/lard+oil - and another one about
its use as a lighthouse fuel in California - or yet another which says
"Lard
oil is a fixed oil obtained by subjecting lard to heavy pressure without
the
application of heat."

Ah - right, thanks. I know what it is now.

The use in California is surprising, I'll have to look into that.
