Is it not a good idea to buy freshly blended oil?

When it comes out of the earth after what a million years someone adds a couple substances to it and now its fresh.

"New and improved!"

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!

Why would you use 20 year old oil?

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.

I agree with this theory as well, which is why I am using 7 year old ESP Formula 5w-30 in my Vette right now and it’s why I will be using the Fram Endurance that I already bought for it, on the next interval. If I paid for something like this I want to get my money’s worth from it.

You're talking about using oil that the manufacturer says has aged out, to save what, $50 in oil, in your car that MSRPs at about $68k USD. I don't understand the economics of that, but I understand it's just a different approach and not my engine regardless.
