What service does the Cummins Particulate Filter require?
• The Cummins Particulate Filter is service-free up to 5,000 hours when low ash oil is used and the base engine is properly maintained. At that point, ash cleaning is required. The EPA has set minimum ash cleaning intervals of 4,500 hours for engines above 173 hp (129 kW). Cummins expects to reach 5,000 hours before ash cleaning is required.
