I would like know what your fuel economy is over a tank of diesel which should include a regen.
The 21 mpg numbers are starting to sound like Bionic Man's mpg numbers. :W
Hey Guys, just so you know, Cummins actually has a very good passive regen strategy and also seems to have the DPF closer to the engine than Ford does on the Super duty. If you maintain average MPH speeds over 40 or use your truck to frequently tow, you may never witness an active regeneration. I seem to have a regen event about every 1,000 miles on the average. The truck certainly runs differently when it does regen. During this summer, it's been more than 1,000 miles since my last active regen, namely because I've been driving to the coast or visiting family on the weekends getting good long drives in that passively regenerate the DPF. Feel free to check my fuelly account by clicking the link in my sig.
I have a 2010 Ram 3500 w/ Cummins and a 2009 GMC 2500 w/ Duramax and have never noticed a regen on either of them. Both have about 40,000 miles on them. I wouldn't know what to look for or if it would feel different while it's happening.
With just over 6K on my 2014 Ram, I too have never been aware of a regen. My first road trip with less then 1K on it I got 19.4 hand calculated. Towing just over 13K I get just over 10-10.5 hand calculated. So far running empty I get anywhere from 19.2-21.5.
