Long Haul service (over-the-road transport) applies to vehicles that annually travel more than 60,000 miles (96,000 km) and average greater than 12.0 miles per gallon with minimal city stop-and-go operation. Examples of Long Haul service are regional delivery that is mostly freeway mileage, interstate transport, and any road operation with high annual mileage.

A Check Engine Indicator or mileage/time intervals indicate when ash cleaning is required. Use DETROIT Diesel Corporation’s authorized DPF cleaning procedure. Failure to follow this procedure could result in engine and/or aftertreatment damage, causing degraded vehicle performance including excess fuel consumption and decreased engine life. Normal DPF ash clean interval is approximately 225,000 mi (362,000 km) (7,500 hrs)1 |
