  Sure, but why? Tesla (and others) built "demonstration"
coils with the primary/secondary assembly immersed in oil
but AFAIK not the primary alone.

  Tesla's stated reason was to minimize corona losses,
flashover (what we today call racing arcs IIUC) on the
secondary, and pri/sec arcs, and he preferred oil because
it's "self-healing". Still makes sense in light of today's
knowledge, but why just the primary?
