Exhaust fluid for 2012 chevy 6.6

[BAMDmax]

What is the best exhaust fluid to use in my 2012 6.6 Duramax? is there much difference between them? I have seen quit a bit of difference in price from one to the other. Thanks for the info.

I'd use a national brand that you're familiar with or recognize, and that has a certification on its label.

Your owner's manual should have guidance on choice of DEF.

I use Terra Caire but couldn't tell you if it's good or bad other than it works.
