I couldn't accept the idea of $8-a-pint oil either.
My approach has been to put some regular machine oil on a piece of paper occasionally and shred it. Dunno whether that's effective or not, but it seems to me like a reasonable way to do it. Back in "the old days" Teletype punches used oiled paper tape, so I'm guessing that shredding a piece of oiled paper will work more or less the same way.
