Hello, all,

I have a question about 60-year-old+ oil in machinery.  The questions deals
specifically with machinery at the Kennecott Mine in Alaska.  There are no
plans to ever run the machinery again, but the question is whether to drain
the oil and replace it with synthetic, drain the oil and leave the
machinery empty (not my choice because I think the parts would rust
immediately in the climate here), or leave it alone.  There's not a problem
with leakage or containment at this point because all of the machinery have
catch basins underneath.  It's not an environmental issue at the moment,
but a preservation one.  Has anyone had any experience with this sort of
thing?

Thanks,
Amy.
