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

Organic heat transfer fluids react (depending on their composition) to oxygen. That is an unfortunate fact.

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.
