Diesel engine oil and diesel particulate filter (DPF) preventive maintenance (PM) service intervals are being extended on all model year 2011 and newer Volvo trucks equipped with the OEM’s D11, D13 or D16 engines, according to the manufacturer.
Volvo Trucks in North America said its adding 10,000 miles to its engine oil and filter service interval for long haul, regional haul and heavy haul duty cycles. As a result, those respective OM intervals are now 45,000 miles for long haul, 35,000 miles for regional and 25,000 miles for heavy haul operations.
As before, though, the OEM stressed that owners must use engine oils that meet Volvo’s VDS-4 standard. Also, if engine idle time is greater than 30%, operators should use the next shorter drain interval, Volvo said.
Assuming a 600,000-mile vehicle life in over-the-road applications, the new engine oil intervals will allow truck owners to forego between four and 16 oil drains, depending on duty cycle, Volvo said, compared to the prior maintenance schedule.
For DPF cleaning, the interval is being extended in long- and regional-haul applications from 250,000 miles to 400,000 miles – allowing for DPFs cleaned just once rather than twice over the course of a typical truck ownership cycle, the manufacturer said.
The OEM added that those updated PM interval recommendations are based on over a year of testing and analysis of customer trucks and returned parts – testing conducted to ensure that those extended intervals would not shorten vehicle life or degrade performance or reliability.
