Yes oil has been in the ground for, we'll go with thousands of years, and if left for a few more thousand years, in theory, it would break down close to the original crude. In reality it won't get exactly back to crude, but it will break down. The oil in the can/bottle isn't crude. It's refined/processed. It has additive, and is slightly toward Anhydrous. Compared to brake fluid, it isn't very anhydrous, but still. I cede that if crude oil were canned, it would only breakdown slightly over a thousand years, yet, refined oil, with additives in a cardboard can isn't crude. Now if the oil is sealed in a metal can, it will last longer, but, it is still breaking down, just slower. Let me use an extreme example, brake fluid or AC lubricant. They are extremely anhydrous, and will breakdown extremely soon. You know how when you open a bottle and top off your brakes, and six months later you go to top them off again? You don't use that open bottle do you? Motor oil isn't breaking down anywhere near that quickly, but, cans from the 1970's depending on how and where they were stored, I wouldn't use them.
