With a focus on reducing the total cost of ownership for customers, Mack Trucks announced that it is extending service intervals for diesel particulate filters (DPFs) and diesel engine oil and filter changes on all model year 2011 and newer Mack® models powered by Mack MP7®, MP8® or MP10® engines. Over the life of a truck, the extended intervals can add up to a potential savings of thousands of dollars. The new recommended service intervals for engine oil and filter changes have been increased by 10,000 miles to 45,000 miles for long haul, 35,000 miles for regional haul and 25,000 miles for heavy haul. Owners whose engines idle more than 30 percent of the time should use the next shorter oil and filter change interval. Any engine oil used must meet Mack’s EO-O oil specification.
The service interval for DPFs has been extended from 250,000 miles to 400,000 miles for long and regional-haul applications. “These extended service intervals demonstrate Mack’s commitment to improving our customers’ bottom lines by reducing maintenance costs,” said Roy Horton, Mack director of product marketing. “Using data from our EPA 2010-compliant trucks, we’ve been able to verify that our newer engines produce significantly less particulate matter, enabling us to expand the service window for DPFs and engine oil and filter changes.”
Compared to the previous maintenance schedules, the extended engine oil and filter change intervals can save between four and 16 oil drains, depending on duty cycle, on a truck with a 600,000-mile service life. The extended interval for DPFs will allow many owners to cut the number of filter replacements or cleanings from two to just one over the life of the vehicle.
