DEF Brands

[Chief Brown]

Just wondering if you guys have a preference when buying DEF other than at the pumps when filling up at truck stops? I have a 2020 Ram 2500 and I have been using the Autozone brand. They sell the Blue DEF but I was just curious if there is any difference between the two other than price. When I look at the ingredients, they both seem to be the same and meet all Federal requirements. This is my first experience with using DEF. I had a 2011 Ram 2500 that did not require it.
