My brother use to work for O&G Service Companies, where they had upward of 100 diesel vehicles that required DEF. There was a time where many of the vehicles started to operate poorly and he brought in a consultant. That dude told him their DEF was aged out and causing the problem. As you can guess, they purchased DEF in massive quantities.
I told him that sounded absurd to me..... knowing what DEF really is. Urea.
Anyway, when the news that DEF was in short supply this past spring, I purchased 40 gallons and it is stored in a cool, dry, dark place.
I wonder how long DEF can be stored..... and if it can really go bad?
