Personally I prefer a little aged and let it aerate for a while.
But the smell is a good clue as to how fresh the additives are.
At least to my Discerning nose!
Bc it's there and needs to be used up. Ran 20+ yo Pennzoil yellow bottle oil in my old SBC 350 just fine for 3-5k miles, can't remember the exact length. Ran 10yo oils in it and some other engines I was given and would use both again without hesitation. Pour half in, shake the heck out of it until the additives suspend again, fill it up, and go about your day. Yes, I watched his video, and yes, I agree it technically does degrade, but I'd still do it again without hesitation. Waste not, want not, my friend, that's money sitting there.
