Well, you can listen to a blender who'd like to have you dispose of your stashed oil after five years or so and buy more or you can take advantage of the empirical results of those here running oil old enough that it comes in cans.
Who are you going to believe?
I think the oldest oil I've run was around ten years old.
No big slug of additive residue left in the containers and no issues noted in service.
