Doug,
It will tend to rapidly overheat, but at $15.00 a cap you're not talking
about much at risk. :^)
Immersing in oil may help a bit, but the real problem is rapid heat
buildup deep inside the capacitor rolls that can't escape rapidly enough
to the outside of the cap. Any extended run-times will likely "toast"
the cap irrespective of whether you put the caps in oil...
