I recently used some old oil (25 plus years) in plastic bottles that had been stored in a semi climate controlled area (attached garage). Poured the first bottle in a pan to see how it looked. No evidence of water intrusion. Had there been water present, it would have sunk to the bottom. They don't stay mixed absent some agitation. It was fine. Not sure I would trust one of the old card board can containers.
I believe as long as it is not subjected to extremes in temperature, there is no problem.
Of course, the smart arse in me wants to say: It has been stored underground for 68 plus million years; how bad can it get after another 20 on the shelf?
