WHAT IS THE SHELF LIFE OF DEF?
TerraCair ultrapure diesel exhaust fluid has a shelf life that is a function of average storage temperature and time. Between average storage temperatures of 68° F and 86° F, TerraCair has a shelf life of 12 - 48 months. Below 68° F, the shelf life of TerraCair is virtually unlimited. TerraCair will freeze at 12° F, but thaws quickly without deterioration. This data was developed by Terra's Technical Service and Product Development Lab.
