Does anyone have any information about how this new Ultra Low Sulfur diesel that will be at the pumps starting very soon will impact the diesels, like mine (2004 Ram 2500 CRD). I may not have a good grasp on fuel but it is my understanding the the sulfur content, up to 500ppm currently in the diesel fuel we use is dropping to 15ppm. Since sulfur acts as a lubricant, I was wondering what impact, if any, it will have.
