the brand doesn't matter, no more than the brand of diesel you buy....it's def.
100,000+ miles and no issues...mainly wllyworld brand, but several others along the way...
by the way, you even probably put water in your def tank, and some accidentally have, and nothing major would go 'wrong', other than your alert would go off saying that it could not read your output correctly, and give your system false readings until you filled it with correct fluid - not that I'd want to try that, but it's not the tragic end as some would assume, it's only a system to help dampen the amount of 'soot' associated with the diesel byproduct. : ) and it has nothing to do with your engine, it's all 'after engine' treatment.
