Hey yall, new member and new GMC owner. Finally jumped up to the 2500 HD Diesel. Looking forward to picking yall's brain being that this is my first diesel. First of many questions, what brand def is best suited for the Duramax or doesn't it matter? Thank you

Welcome to the forum. Can't suggest a brand of DEF, my last diesel was a 1996 Power Stroke and didn't use DEF.
