def
Being a new diesel owner I was curious if there is a difference where you purchased your def or if there are different brands, good and bad?

I buy DEF at truck stops for my semi trucks every time they need it right along with all the big trucks on the road and have never had any problem with it. Now days you never see drivers buying jugs of DEF. I have a 2014 Ford 6.7 and the only DEF that I have ever put in it was bought at the pump too.
