does adblue have a use by date?
Yes. Due to the limited durability of AdBlue®, AdBlue® has a 2 year lifespan from date of production. It is essential that AdBlue® is stored between minus 5 degrees and 20 degrees Celsius. AdBlue® can decompose if it is stored at 30 degrees or more for extended periods of time – ammonia can form in such instances.
