I've never had an oil filled capacitor go bad, leak, or blow.
Like Don, I've had electrolytics BLOW. Those I traced back to STUPIDITY
in having mistakenly placed them in the circuit in REVERSE polarity.
That has happened TWICE. Comes from working too long on a project
without ENOUGH sleep. I'll never repeat that again.
During my military service, I had a "few" instances of taking large
transformers covers off to change voltage taps.
Lo and behold, I've now donated tissues to the "Agent Orange" database.
These transformers were full of Askerel ([sic] I probably misspelled
it!). It was an oil for indoor use that was supposed to be less of a
fire hazard - LACED with PCBs.
So far so good, no issues, although I was in the oil up to my armpits.
