 	Some mineral oils can contain contaminants (including moisture, as an
 emulsion, I'd guess). Try to get a USP grade of mineral oil, if that's what
 you go with. Any medical or chemical supply house carries that stuff in
 quantity. Actually, there are a lot of non-PCB transformer oils out there
 that you can buy (some mineral-oil based, others use silicone or other
 synthetic compounds). You might call your local power company and ask what
 they use in their distribution transformers; maybe they'll give you a few
 litres gratis (be sure that it's new if you get it from there). Silicone
 oils would probably be the best to use since they're completely synthetic,
 quite pure (in a CP grade) and are the least likely to break down or
 oxidize under ozone/electrical stress.

Call your local oil distributor.  I bought my 5 gals of transformer oil from
the local Chevron distributor.
