For example, at 86Â°F, DEF has a shelf life of a year.REMEMBER: Do not equate shelf life to spoiling like food, as DEF will not go bad.IT will lose some effectiveness, and the SCR will dose at a higher rate, but it wonât âgo bad.â If maintained at a constant temperature, DEF manages to stay for several months.For example, at 74Â°F in Los Angeles, Diesel Exhaust Fluid has the shelf life of 44 months. 2..

1 Check the expiration. 2  The storage life of DEF varies, Page says. 3  Its urea is vulnerable to degradation from sunlight and higher temperatures. 4  In favorable storage conditions (proper container, away from direct sunlight, temperatures between 12 and 86 degrees F), DEF can maintain its qualities for about 12 months.iesel exhaust fluid, or DEF, is a solution of urea and water that breaks down harmful engine emissions when sprayed into the exhaust stream of diesel vehicles.
