2013 Ram truck
I'm thinking about getting a new leftover 2013 Ram 3500 DRW 6.7 but I was reading on the TDR about some of the trucks having short oil change intervals. One poster had to change oil 4 times in 10,000 ...

The 13's can put fuel into the exhaust still, so fuel dilution can happen.
How does that work? If fuel is being injected into the exhaust how is it finding its way back into the engine? I though some(maybe the 6.4 Fords) would dump some extra fuel into the cylinders to help with the regen process and over time some would find its way past the rings and get into the crankcase thereby diluting the oil or "making oil". Are you saying that maybe the Cummins also dumps extra fuel into the cylinders and counts on there not being a complete combustion event thereby sending raw fuel into the exhaust when the exhaust valve open? Sorry for the newbie questions, but just trying to understand.
45Ricochet posted a pretty decent link. However, maybe I should have been more clear and note that they do post-combustion fuel injection just like the Ford 6.4 and 6.7 motors do. However, the 2013+ Cummins setups are designed to have more "Passive" events than active events. So as long as you tend to have a roadtrip every couple of weeks, you'll hardly ever witness an active regeneration.
Pretty much a true statement....
