Diesel exhaust fluid (DEF) storage
The shelf life of diesel exhaust fluid (DEF) is
limited, whether it is stored in containers or in the
vehicle’s diesel exhaust fluid tank. There are a
variety of factors that can contribute to reducing
DEF’s shelf life, particularly temperature and du-
ration.
To increase shelf life when storing DEF, keep the
following in mind:● Avoid contamination by storing in sealed
containers.
● Protect from direct sunlight.
● Store DEF at temperatures between 23°F
and 77°F (-5°C and 25°C) to protect from
overheating or freezing.
DEF has a minimum expected shelf life of
18 months, but its shelf life will be reduced if the
above conditions are not met.
It will be necessary to recheck the DEF concen-
tration if it has been stored for an extensive period
of time, or if it has been exposed to water. More
information can be found in the manufacturer’s
Owner’s Manual.
