Ok the following is just my experience and based on what the dealer diesel tech told me about how OCR works.
Bought my 2017 Ford F350 on black Friday November 2017. Truck has roughly 16 miles on it. I told the dealer that one of the only ways I was going to switch to Ford is if they turn on the OCR Regen from the dealer at no cost.
Once turned on the dealer tech walked me through the process. He showed me on the screen how it works. He said that you will now see two new settings, one in Truck Info and Settings on the dash. First the Diesel Particulate Filter Status and on the dash in Truck Info and in Settings you will see Auto Regen.
I noticed that I could not uncheck Auto Regen and I ask "why?". The Diesel Tech told me that the reason why is because Ford doesn't want customers conducting only a manual regen because we may forget to do one and the filter will get so full and cause damage.
Auto Regen is turned on so that the truck will operate normally conducting normal regen processes while driving.
Now the Diesel Particulate Filter Status will read from zero to 100%. Once it reaches 100% it will just read DPF Full. Now the filter is capable of Zero to 200% full. Zero to 100% is normal and is what we will see. The filter is capable of 200% saturation. This gives the truck wiggle room. Now when the truck reaches 120% full (You will not see this percentage) the next time you stop and put the truck in Park it will then ask you if you want to clean the exhaust. It will ask you for couple prompts and once you accept those prompts then your truck will go into an OCR regen.
Conducting a manual or OCR Regen is not something you can do anytime you want, the truck has to meet the right conditions first and then it will decide if conducting an OCR Regen is the best way to clean the exhaust and give you the prompts to initiate it.
My truck conducted its first OCR Regen at 7132 miles. Before then my truck did its normal regen on the highway and sometimes did it in the city. It will reach DPF Full status and then begin to drop to 95%, 90%, 85% all the way down to Zero.
My OCR Experience again took just shy of 30 minutes, once I gave the truck permission to initiate the OCR the trucks RPMs went to 2k and stayed there and then dropped to normal idle after about 27 minutes. After it dropped it said exhaust cleaning complete or something to that effect, I really do not remember but I do remember reading the DPF Status as zero.
Hope this helps.
