Bought a gallon at Knob Creek this past spring, still in its cardboard box, milspec. In any event it did have an expiration date, like 2006, bought it anyway, $35. Works fine, just shook it up. By having an expiration date on it, I would assume the military has some reason it should not be used beyond said date. I can't see anything wrong with using it, I am no chemist, and don't really care if it is expired anyway.
