surely there is mere convection component too?  hotter oil rises to
the top; and might not uneven heating of submerged components cause
other oil circulation patterns?  how much heat is being dumped into
that oil?  perhaps a thermometer might tell something.  sounds like
the electrical effects dominate, but it's not a black/white world.
