Didn't say this is not oil. The point is that you don't need additives in
gear oil, as you will see when you look at axles that are sealed ( in the
sense that there is no drain plug) for life. Additives serve no use in gear
oil. you are using the same argument with the wrong conclusion.

For different reasons. The reasons are that many gearboxes no longer
have srtaight cut gears etc.

True, but the as I said it still remains the fact that oil oxidises
and the chains get broken up.

I'm not argue any of that as I don't have enough founded knowledge
to counter it.
