2010 NEVER regens???

[DFWSRT8]

I have been driving a 2010 with the 6.4 engine. Truck currently has 45k miles on it.

In the last month since I started driving it, I have not seen a single regen on this truck.

It has been driven from Fort Worth, Tx all the way to Omaha Nebraska and back, with a loaded trailer on the way back.
Has been driven to Midland/odessa(6 hrs) and back as well as New Mexico (7 Hrs)and back several times. Not once have I seen a regen on this truck.

Truck runs good and doesn't seem to act funny, although it is averaging 11.2MPG on the highway going the speed limit and no faster. Everything is stock on the truck aside from 35" tires. Factory tires measure 34.4" so I don't think that would make too much difference. Perhaps the DPF is getting plugged off? Makes no sense to me, but I figure this info will help you guys to help me

Coming from a Flawless 6.0(which was stolen last month), where my boost would never creep over 10 PSI on the highway when simply maintaining highway speeds...I am unfamiliar with this truck altogether. I have noticed that this truck will approach 30PSI when climbing up the same small hills where my old truck would peak about 10PSI. Perhaps this above information will be useful to you guys aswell.


There is NO CEL nor has there ever been since I've started driving. I don't have a tuner to find out if there are stored codes either. All temps seem to be as they should. Truck has 90 hours on it.

No answer here but if under warranty take in and let Ford fix it. Ask around in the Texas area or here Lone Star Powerstrokes - Ford Powerstroke Diesel Forum . I am sure someone in TX has a code reader that probably could meet up with you to see if there are any codes.

That seems bizarre. I was going to ask if maybe it did it but you hadn't noticed, but don't that have a warning for when the truck goes into regen? Man, sorry to hear about your MPG though, my condolences to your wallet.

First, you have some serious mods in the way of tires. You are pulling some sort of trailer. Your MPGs are pretty good for some trailers.

As for "seeing" regens, the dealer did something with my latest flash (in August) which disabled the regen notification. I haven't seen one in the past 5,000 miles either. No matter they used to occur every 250 miles like clockwork. I used to reset TRIP 2 with every regen.

OTOH I know its doing it. Periodically reset the fool computer MPG display. If its falling reset it again, you'll see sucky 8 MPG or worse. Reset about 5 or 10 minutes later and you'll see a wonderful 14 MPG for a while until the DPF plugs and it drops to about 10, regen starts, and the cycle repeats.

The "Cleaning Exhaust Filter" message flashes on the display for about 2 seconds and then goes away. It's very easy to miss. There are no other message that pop up unless the DPF is so full it displays "Drive to Clean Exhaust" That occurs if the engine conditions never allow a regen to start, like coolant never reaching 160F or repeated regen interruptions, and soot continues to accumulate above normal regen trip point.. In that case, "Cleaning Exhaust filter" supposedly stays on until it's done.

I know when exactly mine goes into regen from the sounds of the engine, but it's easy to miss on the freeway since road noise drowns it out. Boost drops rapidly to zero when regens are active.

You can check for regen by pressing the system info and wait until it scrolls to the end of all the messages. If it's in regen, it'll say 'Cleaning Exhaust Filter" just before it displays the odo.

Mine will regen approx every 250-275miles. It'll feel real constipated just before regens.

I calculated about 1-2gallons of diesel are burned per full regen or about a 5-6% fuel penalty; less on freeway, more in stop-and-go traffic. Stupid DPF and regens are the source of all evil in this truck!!

Any news??? Sounds like you maybe missing the notification. On another note, I say delete to save your money, but more importantly to save your truck. If you plan on keeping this truck for long, you need to educate yourself about oil dilution!!..... Most on here average 18-22 while driving modestly.
Good luck, Dom

possible that it has a dpf delete tune on it?

Another reason could be the fact that he is always pulling trailer. Trucks and new tractors that are under constant load keep the dpf temps higher and need few regens, it's the putsing around town and stomping the skinny pedal from a stop that really plug up the dpf fastest.

Yup, that's called passive regen.

It occurs when you drive the truck hard and long enough for the EGTs to naturally reach a high enough temp where the filter is being cleaned and the computer no longer feels the need need to artificially boost EGTs by using the regenerative injection event to clean the filter.
