• A one time inadvertent tank of diesel fuel with greater than 15-ppm sulfur content will not damage the engine and aftertreatment system. The system will clean itself out when ULSD is re-introduced. However, continued improper fuel use of sulfur levels greater than 15-ppm with Cummins Tier 4 Interim engines can permanently damage the engine and aftertreatment systems within a short period of time. This damage could possibly cause the engine to be inoperable and cause unplanned downtime and expenses.
