DEF Fluid

[Tomtwhite]

Are all DEF fluids the same? The dealer of course recommends Mopar fluid. But certainly I can get it much cheaper elsewhere.
Any thoughts?

It's all the same, I buy from the local station's pump, and have also used DEF from Walmart as well.

All the same as already said. Can buy it literally from anyone that has it on a shelf. Ideally only buy something a few months, certainly less than a year. And no need to keep the DEF tank at full, you want that crap to burn through as it does have a "shelf life" even in the tank.
