If adding the Delo oil, I don't smell the burning oil when adding 80/90 gear, the lube smells inside the cab if I turn on the A/C or not. I don't have any oil leaking my engine.

gear lube smells slightly different than engine oil because of the added ingredients. If you can smell it then you were also smelling the engine oil too. You may have gotten so used to it that you did not notice it any more, and now the gear lube is making you notice it.
