Well this is true, but one will never know unless your a Cummins ECM Engineer. Cummins does have break in modes on some of there engines, on all of them who knows. I would not put it past them to have some kind of internal break in procedure, set on run time hour and what not.
Also There are lots of other manufactures and engine companies that do have a derated break in... BRP has that on there new sleds and pwc's.[
Thank you for the info. It would be interesting to know at what level it is. I mean mabey it would explain alot of mpg complaints?
No, the regens are for the ever unless you do full delete.This is good to know. I have recently purchased a 2017 and have logged about 3,500 miles in just over a month. Mileage definitely gets bad when it regens...5-7 MPG for about 20 miles. I have noticed that it seems to do it more with more city/stop and go driving. other than that the worst tank I've experienced was 17.5 and the best 21.5...trailering a 2 horse trailer (~7500 lbs) from Atlanta to Panama City, Florida I got 11.5, beats the heck out of my 2002 F150 at 12.5/15 and 8 pulling the same trailer. Do the regens stop at the recommended 6,000 mile breakin?
