Do all of the thermal oil fluids need to cover by nitrogen gas blanket to avoid oxidation? And in which case they oxidize?

RE: Mechanical
For temperatures up to about 60 oC (140 oF), they oxidize slowly; however, above 140 oF they oxidize rapidly.
As a general rule, the rate of change doubles for each 10 oC rise above 60 oC, and the usefulness of the oil is substantially reduced.
Maybe you could look into non-organic synthetic fluids - but they are much more expensive.
