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. However what Cummins did was that they tuned the motor to produce less particulate matter in the first place. So DPF plugging is a slower process on a new motor and all NOx treatment is handled downstream (EGR is only used to reduce PM production, no longer needed for NOx control). So the newer trucks are intended to regen mostly in a passive manner. As long as you get a few good long trips in every month or so and keep the short-trips to a minimum, you should rarely notice an active regen. I've only witnessed 3 active regenerations in the 3,000 miles I've owned it. My fuel mileage still remains fairly high as well.
