Oil vs Epoxy coils.....

Anybody have any thoughts??? I know epoxy was meant for high vibration. Does oil actually cool better? Thoughts??

I prefer epoxy because there is zero chance of a leak like oil filled.
If they leak, not only does it make a mess but they fail so I run an epoxy E core and I notice it barely gets warm.
