I've got a chance to buy one for $200 (or $3.64 a gallon) which is a good deal. It might take me 2 to 3 years to use it up.

Is this Synthetic oil or conventional? I would say synthetic would have a longer shelf life. Probably at least 5 years. What usually makes motor oil go bad is the depletion of the additive packages. With conventional oil, it is a bit more hydroscopic than synthetic types. But if you heat it up, as run for over an hour in a motor, then the moister should cook off.
