I have read only minor amounts about corona,  but suspect it is not to be
encouraged in the secondary unless you study that sort of thing. I do not know
a lot about Tesla coils, but suspected that the oil would help prevent shorting
out the primary. I understand that spacers are available that would allow a
layer of oil between layers of coil.
