Not really something I would use... Are you meaning using oil as a conductive fluid like water, or submerging everything, like in the Tom's video? I would think that if you used it as a fluid, it would break down the rubber grommets and vinyl tubing. If you submerge in oil, the PCB would soak it up and you really just have 'soggy' components when you remove them.
And no, putting your PC in a refrigerator or freezer won't really work...google it and see the results. LOL.
