I tow and drive interstates almost all the time. I had a 6.4 and it would regen 3 to 4 times per fuel tank which consumed a lot of fuel. This 6.7 is totally different. Depending on how you use the truck. I typically drive 1,000 or more miles between active regen cycles. Running the motor all day under load just makes it passive regen for significant amounts of time, so the fuel consumption of active regens is improved by something like 800% if I try to figure the impact on my fuel usage during exhaust cleaning events.
I don't pay attention to it though, the only thing that I can tell during an active regen is that familiar smell of the exhaust. The performance of the motor is virtually un effected.

Ok. What I have been monitoring is the active regen. Every time it shows up on the screen in the gauge cluster "cleaning exhaust filter". I'm assuming that the truck doesn't tell you every time the DEF is injected, this is the passive part that helps reduce active regen? Then the active regen is like the 6.4's and just shoots raw diesel fuel into the DPF?

My understanding is DEF has nothing to do with regeneration.
