Almost 1/2 my spaces seemed to disappear on that last post... Odd.

 

F16Vip3r are you using a fuel additive? I scanned your posts here and didn't see any mention of it. What you're reporting is EXACTLY what I see when using Motorcraft PM22A. Without it I go back to 120-160 miles between regens. Optilube XPD has very little impact, even at the max conentration of 0.5 oz/gallon.

 

It looks like you copy/pasted from Word, did you?
(it can mess with the formatting)

 

Ford said no wrench no problem...

So They are not willing to look at the issues. Seems like a lot of people are having the same issue. But ford is unwilling to look past the part where the fault might not be caught by the software. You can't have a sensor and software for everything.

I read the trouble code that where posted earlier not one of them measure how fast the DPF is being loaded by soot. There is also no code for how much of time a truck is in regen. Those two condition should be checked for.

So that leaves me these options
Sell
Delete
Lawyer up
Live with it until throws a wrench.
Drive the truck in way that will overload the DPF and cause a wrench light.

Right now I am thinking of deleting. I don't want or need more power.

 

PM Crystal, see what she can do to help.

So far my experience with Ford dealerships is pretty hit or miss, but mostly miss. Either the techs do not know how to troubleshoot things or are not allowed to do so, and in most cases it sure seems like the former, not the latter. If the computer doesn't tell them what's wrong, they don't know what to do.

I had continual issues with the rear view mirror camera backup system since the truck was new. The camera in the tailgate was replaced three different times before they finally replaced the rear view mirror, which turned out to be the problem all along. And of course the last camera I got stuck with was misaligned with the black dashes being off-center. I was so tired of dealing with it that I decided to just live with it, but I'll probably go back and ask them to change it again before the initial bumper-to-bumper warranty is up.

I had a similar dumb issue with the cooled seats recently, which weren't up to par. They've always been somewhat disappointing, but they had become almost entirely worthless. They had the truck back there with a temperature probe and all, pointing out that I'm an idiot because the cooling element was still cooling. I asked if there was a filter or anything that could be causing a lack of airflow, but I was assured there was not, that I was just an idiot who didn't realize that it was summer outside and therefore the cooling of the seats wouldn't be as noticeable. Of course, it turns out there is indeed a filter, and it needed to be changed. The cooling feature of the seats are now back to being disappointing but not entirely worthless.

I also have an issue where the rear backup sensors go off inappropriately from time to time. It used to be only rare occasion, and it's become more often, though not every single time. I brought it up to the tech I had been talking to briefly, and he just brushed it off and said well sometimes they get dirty (happens even immediately after a car wash sometimes), and I didn't have time to deal with it right then, figured I'd handle it on the next oil change. In the interim I ended up going ahead and getting Ranch Hand Legend bumpers front and rear like an idiot. When I brought it in for an oil change and to look at the backup sensors, they said it's the bumper's fault, that their "pinpoint" testing (the same one that repeatedly told them it was the camera that was bad instead of the mirror) showed it was the inside two set of backup sensors, even after they swapped them around, and the tech never documented that I had brought it up before I ever put on the Ranch Hand bumpers. So I'm basically screwed.

So basically I'm glad this forum exists so I can figure out what they don't know.

 

We're getting all wrapped in the fact that 50-90 miles between regens represents an issue.
How do we "know" that? Because it's different than when it was new?

Did we design this system? Are any of us real experts here, and I mean engineering types that have design responsibility for these types of systems? All conjecture.

I've learned my lesson. After nearly a year of pulling my hair out trying to figure out why my truck regened more often than a co-workers truck, I figured it out. Turns out it doesn't. He just never really knew how often his truck regened. After we put my Edge CTS on his truck, it acts the same as mine. No perceptible difference as far as the distance between or frequency of regens.

If it runs good and strong and it's not throwing a code, just drive and enjoy it. Short regens don't burn much fuel. The conclusion I came to is whether it regens every 60 or every 160 miles makes almost no difference in fuel economy. At the end of the day, week month or whatever, I'm ALWAYS at 16.4 MPG - no matter what!

 

So a regen every 100 miles is 10- 13 percent of the time. As far as fuel usage it goes way down. So what is expectable? The ford manual says 100 to 600 miles for a regen. I have fallen below those level stated. Also shutting down the truck when it is at 1200-1300 is not easy on anything. On another Diesel I get 300 miles doing the same drive. Why is this one different? The other is a 6.4

I know what you are saying about being happy. I'm truly thinking about deleting the DPF/SCR, to be happy. I really don't want to fight. I contacted Crystal let's see what happens.

 

I have tried different fuel brands and noticed changes in my regen frequency, also I noticed when I first used optilube at .5 oz per gallon I went about 60 miles between regens, also I switched to rotella t6 at the same time, I wonder if that effects anything.

 

Have you tried it without PM22? I think you'll be pleasantly surprised.

Just make sure you run your tank down as far as you feel comfortable with to dilute the remaining additive as much as possible. I ran mine down below 1/4 tank before refueling, but I saw an additional improvement after a second fill-up.

As I mentioned before, Optilube XPD is not quite as bad as PM22 for regens, but it's not as good as just fuel with no additives either. I use Mobil fuel.

 

why not spend 1500 or whatever it cost to delete all that crap? then you dont have to worry about it

 

I have always used pm 22. I can try a few tanks without.

 

Romeo- I do not use any additives, just straight Diesel… Also, I’m with Donovan in the fact that the Diesel Supplement says 100-600 miles between regens, and I’ve ONLY seen that while loaded up. I would think 100 miles = city driving, and 600 would be for heavy towing. 300 might be agood estimate for unloaded highway driving (these estimates are conjecture, butseem reasonable). If I wasn’t reading what others are posting, I’d probably not know the difference. Though even those like you who say "most people just don't know when they occur" have more distance between each than me. Maybe my regens are at ½ the distance of everyone else? Then is 10 minute regen duration also 1/2 the normal duration?

For me, I lived in temporary housing near my work for about2 weeks. During that time, with lots of short trips (2-3 miles at a time going to/from work and in-processing all over base), I saw regens as frequently as every 15-20 miles. And now 40-50 miles in between is about average unloaded. I’ve tried 3-brands of Diesel: Chevron, Shell, and AAFES (or whatever brand they buy) with the same results.

I haven’t said anything to Ford yet, since otherwise the truck runs great… No issues noted at my first oil change either (Works Packageat Ford Dealer). I figured the Supp was maybe false advertising, or that my truck would “settle down” once I got into a routine.

Donovan- Please keep me posted if you learn anything new from Crystal. I'm skeptical about deleting since that would void the Lifetime Powertrain Warranty that came with my truck. The salesman I purchased from was one of the most pain-free/low pressure/most knowledgable I’ve ever dealt with, and I’d be willing to go back to them to have the truck checked out. Of course, they are located in GA and I’m back in middle-of-nowhere CA (again). I’ll probably shoot him an email anyway to seewhat he knows…

Also, YES, I cut/paste from Word since this website has a tendency to kick me out when I hit submit. Hopefully "previewing" the post will allow me to catch the errors.

 

I just re-read the paragraph on “Active Regeneration” in the Diesel Supplement. It says:

“The frequency and duration of regeneration will fluctuate as both are determined by how you drive your vehicle, outside air temperature,and altitude. For most driving, regeneration frequency will vary between100-500 miles between occurrences and each occurrence will last from 9-20minutes. The duration of regeneration is usually reduced if a constant speed above 30mph is maintained.”

Since the process relies on HEAT, and higher (engine) heat is better for passive regeneration, I would THINK that 100+ degree temps would cause LESS regens than in a cooler environment? Maybe the fact that my wife was taking the truck from the high desert to relatively cool LA Valley allowed her to get better mileage due to less regens from cooler air (referencing a previous post of mine)? Do hot temps cause more frequent, yet relatively shorter regens? I thought that my “shorter” regens (~10 minutes) were a product of being on the highway when they occurred.

Donovan- Are you also in a desert environment at about 2000' elevation?

I HATE when the manual only gives you enough information to have MORE questions… Where’s the “ask the engineer” forum for the 6.7? They had one for the 6.2 when it came out in 2010 for the 2011 models.

 

2 questions for a newbie, my truck will be here next week.

1) is the powerservice additive any good? Ive always used the winter and summer ps in my 6 liter adding 2 stroke oil in the mix as well

2) I drive 7 miles each way to work 7-10 min drive, is this going to be a regen mightmare? No mention of this BS in the brochure!

 

My commute is 8 miles, but I stop and go about 7 to 8 times in that distance which makes it worse. If I run nothing but my commute for the distance of a regen cycle, I end up with less than 100 miles per cycle. If I can mix in some longer runs and maybe a few miles on the highway, I can muster 150-180 miles. If most of the cycle is long runs I average 180-210 miles. If I am towing my 15,500 lb toyhauler and pulling the guts out of the truck constantly, it goes 500-600 miles before it automatically goes through a cycle even though the filter will be clean at that point. The harder you work it, the more passive regen you get. When I'm pulling the trailer, I can watch the soot level drop constantly because the exhaust temp stays over 700 all the time and climbs above 1000 at times.

Do not use 2 stroke oil in DPF equipped truck. That is just asking for filter clogging trouble. These engines require low ash oil for that purpose and directly burning a high ash oil in the fuel mix is only going to create 50 times as much soot to plug the filter faster. Every few tanks I run an additive such as Diesel Kleen or Lucas or Howes and Just about every lubricity additive that I have used causes shorter regen cycles.

Somebody mentioned the use of Rotella T6. I was using Valvoline Premium Blue Extreme synthetic and tried to be a cheapskate and use T6 one time. The entire time that the T6 was in the engine I had very short regen cycles. It was almost as if someone had flipped a switch. I dumped that oil several thousand miles early and went back to a known quality oil and it was as if the switch had been flipped back the other way. Many people swear by T6 and I used to be a huge Rotella fan until I had a 6.0 and had issues with their oil, but the only way I would put Rotella in my truck these days is if nothing else was available and I was desperate!
