Transformer oil

From: Alan J. Hawk <hawk>
Date: Wednesday, February 27, 2002
We collect a number of items that use high voltage transformers,
notably X-ray machines and electron microscopes.  (NB: I have been
assured by several knowledgeable sources that these types of
transformers did not contain PCB's).  These transformers contain oil
as heat sink/coolant.  The transformers are heavy grade steel.

Generally, since I have left the oil in the transformers unless
there is a logistical reason remove it (to reduce weight).  Is there
a conservation reason to remove it or should it be left in there?
Does oil have inherent vice that could haunt me later down the road?
