DPF at 85%
Ok question, I have (in signature) 2017 F350 XL 6.7 dually with only 12K miles on it. Last time in for oil change asked my dealer to enable the DPF% and manual Regen on my truck. Noticed late last night that it's at 85%. Went out there this morning planning to do a manual regen in the driveway and there is no option to start it? We hare towing our Big 5th wheel to our summer spot on Wednesday. Don't want to get stuck with towing our 18k 5th wheel with truck doing a regen. Should I drive the truck around today to let it do its regen? This is my 1st diesel with the DEF and DPF crap in it.
Thanks and take care.

Why not? It's totally fine and your truck will regen every 500 miles regardless. So if you plan is to never tow and regen, you'll be stopping a lot

LOL ok, totally overthinking it!! Shouldn't have had them enable the %Screen for the DPF LOL!! Stupid EPA!! Thanks for the quick responses. A 2005 pulled into a parking spot next to me the other day and man I miss that diesel engine sound. Never thought I would but I do.

You can only enable a regen at 100% full and it must be stationary. If you're headed on a long trip, just let the truck take care of it. High heat is exactly what the doctor ordered for a complete and thorough regen. Don't overthink it. If you do a lot of stop and go driving then the stationary regen is a handy option.

I would have thought so as well, but it's actually much slower when towing heavy for me.

The manual regen process, like the users above stated is a stationary only process. Your DPF % screen has to be at 100%. 99% of the time your truck will take care of it itself for regeneration. There are a few of us that drive for weeks without going over 30mph and don’t have the option of increasing the speed during this time frame. In this situation, manual regen would be needed.

It will be slower when towing. Sure your exhaust has temps are higher but your soot output is also higher. While towing, your intervals between regen will drop from about 500miles to 400. (Info from another user for 100mile interval loss).

That's the case for me, I only drive 5 miles a week to the commuter rail to go to work (I work in Boston no parking for my truck in there, truck doesn't fit in all the underground garages) Tow the camper about 6-7 times during the summer. That's why I asked the dealer to enable to manual regen. Our summer spot is only an hour away. Not going to worry about it, I will let the truck do it's thing. I think i was totally over thinking this regen crap!! Instead I will go out and give it a nice wash and wax.

These emissions controls systems are crazy but a lot better than then they were in 2008. I had an 08 Ram and after I got home from a 1200km drive, as soon as I pulled into the driveway at 2am a message would appear saying regeneration needed Drive to clean. You had to go drive it then or there was a 50/50 chance that your truck would be in limp mode the next morning. Drove me insane.

You really don't have to worry or even think about regens anymore, that's why Ford designed the system with little insight. They don't want the end user even bothering with it at all.
Think of them this way, every once in a while you'll drive a few miles where you get a little worse fuel mileage. You might not even notice it happened. And it was designed that way.

I drive mine mostly in town and rarely get to stretch her legs on the highway. I don't tow and OCR is not available on the King Ranch. I have found regens in the city will complete much faster than on the highway because there's less air moving underneath to take heat away from the DPF. I've witnessed my DPF% screen drop from 99% to 0% in about 6 to 8 miles several times. Regens seem to take 20 miles or more at highway speeds.

The reason we have the soot screen enabled on these trucks is to be sure a regen completes once it's started. Uncompleted regens causes excess fuel dilution in the engine oil. Also, the DPF has a life expectancy, fewer regens = longer DPF life, not to mention multiple recurring regens is a waste of fuel.
