2 many regen's
Getting a regen almost everytime I go out!!!! No joke been going on the past few days. Mostly just "in-town" runs but I have been getting the truck upto temp. MPG is down to 9.7 WOW
I normally see 13-15 or around that in town. Ideas????
I took it out on the highway and held it on the floor for a bit...didn't help or hasn't yet
Had the flash about the last TSB in may I think

Sounds to me it's not finishing a full active regen but you're driving enough to prevent the "drive to clean exhaust" message.
It won't begin the regen process immediately once you begin driving but could use an open road drive for a half hour.
Once warmed up, if it's due for a regen it will start soon after that point.
If you miss the message, keep an eye on your instant fuel ecomony screen and you'll most likely notice.
Flooring it only adds to the problem.
Epic's solution is best but long steep grades are difficult to find in some areas of the country.

This thread is a good example why Ford should be providing more information to the driver on the status of the regeneration process. Knowing whether or not you are in a regen and if it completes would help.
Being able to the see a percentage of back pressure leading up to a regen AND the ability to manually start one at your discretion would be ideal. I can't tell you the number of times I have seen a regen started witin a couple of minutes of my destination...

That is one of the reasons I got sick of diesels with all this pollution crap on them. Getting bad when the truck dictates how and when you drive your truck. If you have periods where you just do a bunch on local running around at low speeds and you run into situations like this where the truck never gets to finish a regen. Then you have to change your driving habits to include a drive on the highway whenever it goes into regen so it can finish. Yup go out and burn even more fuel. Still can't figure out how this is supposed to be better for the environment. It is not that it causes the trucks to burn more fuel, but the fact that the extra fuel being produced because of this in turn adds more pollution to the environment. Also it is a non renewable resource so personally I think efforts would be better spent on making them more efficient. By that I don't mean smaller and less powerful either.... OK rant over.

Good timing - I was just about to post on this very topic.
I had the recent opportunity to complete my first family road trip of the summer (1180 miles worth of interstate, state road, and in-town driving at Myrtle Beach SC) and had the chance to observe the behaviour of the truck over long hours on the road.
First the good news - managed to average 20.2 mpg over the entire trip (250, CC, SB, 4x4, 3.31, usually run about 5 over). Truck did great, no hiccups, no problems, comfortable, quiet, and family friendly. A truely amazing full sized truck.
The only irritant was the regens - I averaged 170 miles between regens (I had 7 that I recorded including two incompleted regens due to traffic or stops along the way). This seemed excessive for what was a light load and mostly non-stop driving.
Is this inline with other peoples experiences? Should I be excited instead of frustrated. It seemed that regens were far less often in the winter months, but I did not record them each time they occured like I have been doing recently. Just throwing one out for the team.

Burn more fuel to creat less pollutants?
No thanks. I will eventually own another diesel but it will probably be older.

My regens are way to often!
And i dont want to hear the stuff like you dont drive it enough or you push the throttle to far, or that is normal.
I used to get regens every 400-500 miles
Now 100-150 it hit a new low today of 12.9 mpg while on the hwy for 30 minutes @ 70 mph
I am sick of regens
My milage feel from 18+ to 15
I drive hwy every day should have plenty of time to burn off
Cant wait for warranty to end so i can program
But with all these issue maybe i need the warrant to last.
Going in again next week for trans

I also agree with the whole regens are dumb issue.. how are you supposed to lower emissions when you're burning MORE fuel? Wow.. you're lowering the soot output....soot which eventually falls to the ground because it is heavier than air..this is what happens when the govt. gets its fat stupid nose into things. With all of the fires and such that have happened over time, if the soot stayed in the atmosphere the sky would be brown.

Understand that the DPF is a big, ceramic filter that catches the black soot and holds it until burned off. Nailing the throttle will only pump unburned fuel in the form of soot into the exhaust and will build up in the filter. It's simple physics. The more efficiently you can burn fuel, the less the waste will build up. The driver can do a lot to minimize the need for regens but at the end of the day, the back pressure sensor will signal a regen when one is needed.

I understand your idea of cleaning it out and for the older trucks (say 7.3L or 6.0L) I have used that excuse.
Even it it doesn't help it's fun and you can pretend it helps clean things out.
With a DPF truck, you simply clog the filter more due to more soot produced with stomping it.
You can stomp this truck all you want, there is still no soot coming out the exhaust tips but it's there and getting trapped.
I have driven the same for the past 13 months of ownership and I have a few more regens and less MPG this summer than I did last summer.
Still not that big of a deal but it certainly isn't as good as it was 3-7 months of ownership.
