DPF regeneration

I've had two 6.7s and they seem to go along way between regen. One thing I noticed, and you can call me crazy, but when I bought the 2011 it had a number of free oil changes, so I used the regular Ford diesel oil. After the program was over I went to Mobile synthetic for diesel, 10 w 40. I noticed right off how much further I could go without needing to add DEF.

Fellow 6.7 owners,

In April, DW & I purchased a 2015 F250 with the 6.7 diesel. Gotta say I love how it tows our trailer. Goes down the road like it is not even back there.

My question is about the DPF regeneration cycle.

It seems like the DPF goes into a regeneration cycle at least once every tank of fuel. And it does not seem to really matter what type of driving I do.

Nine hour steady interstate at least once during the nine hours
Commuting to work 10 miles back roads, 25 miles interstate

Does this seem normal?
What triggers the DPF to go into a regeneration mode?

Thank you

Completely normal... Keeping this process simple the regeneration is triggered by a exhaust pressure sensor that measures the backpressure on the DPF. As the DPF collects more soot the DFP becomes more restricted therefore more exhaust backpressure builds up. Once this backpressure reaches a certain threshold the regeneration process begins to burn off the soot particulates. My truck typically takes ~10 miles at highway speed to complete a regen. A simple way to watch for a regen is to watch your instant fuel mileage screen as you'll see your instant fuel mileage drop to ~12 mpg when this happens. Also this same screen is a good tool to know when the regen process has been completed.

I'd probably go to the FTE.com (Ford Truck Enthusiast) site. I have a 6.4L diesel and mine regens about every 400-600 miles. Its supposed to clean accumulated soot from the DPF. If you catch the notice on your dash, take it on the highway until it shows it's cleaned. I dont' know about 6.7L, but on mine the dash notice comes and goes quickly.

Regen is computer controled using inputs from the DPF. More soot, equals more regene.
