Longer DPF Cleaning Intervals

Cummins has announced two enhancements for its heavy-duty ISX15 engine: an extended diesel particulate filter (DPF) ash-cleaning interval and the Encore Xtra protection plan.

The 2016 ISX15’s DPF can reach an ash-cleaning interval reaching up to 500,000 miles (804,672 km) for conventional linehaul applications with fuel economy greater than 5.5 mpg. How did they do it? Cummins credits design enhancements that reduced oil consumption and ash accumulation.

Encore Xtra is a new in-service extended protection plan available for 2010 and 2013 ISX12 and ISX15 engines. The plan must be registered by 6 years/650,000 miles and after any current extended coverage has expired. While traditional Encore plans have only been available to used-truck buyers, Encore Xtra is also available to the first owner in recognition of some customers’ longer trade cycles. With extended maintenance intervals and increased peace of mind, Cummins says the result is lower cost of ownership for the first owner and increased residual value at time of resale.
