Why is electronics fine when places under oil but not on water?

Question

So I’ve seen some videos before where they literally put entire pc builds in oil and some machines work under oil (although I forgot what machines are those)

Answer 1

I’ll go with the the consensus that oil is a much poorer conductor than water, and so circuits are much more likely to work in oil than water.

It should be noted that oil has a higher dielectric constant than air, so it is possible (if not particularly likely) that some high frequency circuits may operate incorrectly if immersed in oil when designed for use in air.
