air 1 def?
 

Anyone use this stuff in there 6.7? I would think its basically the same as the peak def and ford stuff . I actually can get a smoking deal on a few 2.5 gallon containers

It looks like the same stuff as Peak. I use a brand called Super S that my fuel stop sells in 2 gallon jugs for under $6. I just check the labels...if it is the same percentage of urea as the other stuff I use it.

I haven't used it (as far as I know) but all three follow ISO-22241 so it meets the SCR standards. Yara is a huge distributor.

Yeah I checked the ingredients but didn't see any on the label. Says for scr systems
