The entire reason of going to ultra low sulfur diesel in the fall of 2006 was because the manufacturers demanded it for EPA2007. ULSD is <15 PPM sulfur; LSD is <500 PPM.
LSD poisons the precious metal coating on DOCs/DPFs in very short order.
Stamped right on the Caterpillar DPF I was servicing the other day: "<15 PPM ULSD".
