Aftertreatment Device Operating Requirements

Aftertreatment Device (ATD) Operating Requirements - Ops - DD5, DD8
Notice: Not following the operating requirements may result in damage to the Aftertreatment Device (ATD) or accelerated ash plugging of the diesel particulate filter.
Notice: Do not use kerosene or fuel blended with used lube oil.

Oxidation of particulate matter is the key to filter performance. This requires that the catalyzing agent (platinum-coated passages) provide optimum enhancement to the oxidation process. The following requirements must be met; otherwise the Aftertreatment Device (ATD) warranty may be compromised:

  • Use Ultra-Low Sulfur Diesel Fuel (ULSD) with 15 ppm sulfur content or less, based on ASTM D2622 test procedure.
  • Lube oil must have a sulfated ash level less than 1.0 wt %, currently referred to as API FA-4, CK-4 and CJ-4 oil. Detroit™ currently recommends DFS 93K223 (API FA-4) for optimal fuel economy, however, DFS 93K222 (API CK-4) may also be used.
