I'll double check my oil again. That's a great piece of news though. Don't have to make a moonshine run.I have to believe the DuramaxTuner turns off EGR. Easy way to tell - if your oil is not inky black, EGR is turned off
My belief is with EGR off, the DPF will receive less soot and last longer. Mine only gets the BBQ treatment every 725 miles. Pretty confident I will not have any DPF issues over the life of the truck.
If it does happen, there are DPF cleaning services now for light duty trucks, you don't have to throw it away. Evidently these companies can "shake and bake" them, heating the DPF super hot, and then blowing huge quantities of compressed air through can flush 'em out. They will also cut the DPF open, clean the element and weld them closed again if needed.
