IF it utilizes a diesel particulate filter (DPF) or a NOx adsorber that requires regeneration, and IF the engine uses a late injection event to generate the heat required for the regeneration cycle, there's every possibility that the engine can "make oil" due to fuel dilution of the lube oil during the regeneration cycle. How much of a problem this is becomes a function of how many regeneration cycles are required. Typically, engines that are on the highway pulling a load will require significantly fewer regeneration cycles than engines in "mall cruisers" that spend most of their lives at idle and low loads.
