Manufacturing date of DEF

[Runaround]

Can someone tell me the manufacturing date by looking at these pictures?
Well I can’t get the pictures to load.
Maybe someone can tell me how to decode the numbers on the box. I don’t see anything that resembles a date. This is the Drydene brand DieselAll DEF.

Sometimes those date codes can be a bit mysterious, so give them a call:


Or choose the Contact Us option to ask the manufacturer:

DEF is cheap, if you are not sure just dump it and buy new.

The company I work for just bought a pallet of it and I am just curious. I’m sure it isn’t old since they just bought it.

BLUE DEF has a screwed up code
Maybe others use the same system

I personally use Super Tech DEF, i buy it at Walmart
They print the date so that it is understandable

Blue DEF uses the ISO dating system
