- Yes. About a year if stored properly (Some places say 2). If you buy a bottle, there should be a date code. I would only fill up when needed, with what you need.

DEF will degrade over time depending on temperature and exposure to sun light. Expectations for shelf life as defined by ISO Spec 22241-3 are the minimum expectations for shelf life when stored at constant temperatures. If stored between 10 and 90 deg F, shelf life will easily be one year.
