Yep too bad...

But before someone says it...

"Just delete... problem solved."

 

My 21' runs low 600's when not in regen and this is fully warmed up down in the Keys.

 

My 16 does that. What he's alluded to is because of the location of the 9th injector in the DPF. EGT 1 and 2 for the 23+ trucks stay cooler because the magic is happening directly in the DPF because the fuel is injected there and not on the exhaust stroke on our engines which heats up EGT 1 and 2 more. But these new 6.7s appear to have 5 EGT sensors.

 

Fresh oil change with a sample just prior to regen and after in pre 23' PS would tell you all you need know about oil dilution due to regen.

 

I don't let my truck idle much. I used to start my truck up when I was putting on my boots before work in the winter but after seeing that video from Dave's Auto Center in Utah about fuel dilution, now I walk outside and get in. Start, put on seat belt and drive off. Keep it easy and when I hit the big hill for the way up, do not hammer it, keep it at no higher than 2k RPMs or so with a reasonable speed, and let the impatient **** ers behind me pass me.

I do get my oil sampled. Not this recent change, but last change is still sitting on my desk... I put the "Pro" in procrastinate...

I do get some but not crazy and due to the injection of excess fuel on the exhaust stroke of pre 23 trucks. I let the truck tell me when to change which is usually just over 7k to 7.4k miles.

 

Since day one I had always heard letting them idle was not good for them. Like you I always turn the key and start out without putting the coals to to it until the truck hits normal operating temps. I was told explicitly while still working in house that they did much better under load and not in stop and go use. "Heat em' up and work them" was the quote.

 

I track what’s going on with regens on my ‘14 using the Exhaust Filter dash display that the previous owner must have enabled with Forscan and an old iPhone connected to a Bluetooth OBD adapter using the OBDFusion app. My regens happen every 200-250 miles under normal driving.
There is a PID that displays 0 or 1 for regen status so I can see if I missed the message it has begun. I monitor EGT 1 and regen status along with a slew of other things.
Towing my 8k pound trailer last week 180 miles round trip I started at 75 percent on the exhaust filter and ended back home with 65 only through passive regeneration. The big grade coming out of Mitchell, OR towards Prineville burned off about 40% before it climbed back a bit on the way back to home. It really makes a big difference to get things warmed up and working. Most of the trip EGT1 was between 600-900, peak was just under 1000 if I remember right.

 

I have a '16' this is what was done when bought new from dealership. Had them activate it so % can be seen.

The dealer activated mine as well when I had the warranty and had in for service for whatever...

Good post Rat.

 

How many miles on yours?

And what's normal driving for you?

You got a lot of passive regeneration out of it when pulling weight which is normal because trucks that work pulling loads all the time usually have no issues. Pulling the trailer gets the EGTs, actually EGT4 which is the temp of exhaust coming out of the DPF, hot enough (at least 572 degrees) to passively (without an active regeneration) burn off the soot being constantly produced by incomplete combustion, which soot is unburned fuel because no truck has perfect combustion to burn all of the fuel in the chambers, and keep the DPF from going what Ford considers "FULL," because it's not completely full or else there would be issues and you would get a "DRIVE TO CLEAN" message and possible CEL codes.

I daily drive mine, with 137k miles, and usually go out to at least 400 miles.

 

Im at 125k. Normal unloaded driving is about 70 percent highway 30 percent city. All the fuel I burn has some biodiesel in it, don’t know if that makes a difference. I use PS Diesel Kleen every fill.
It seems like with a trailer on it would easily go 500 miles without a regen.
Engine oil seems to have an effect even though there’s no noticeable use on the dipstick. When I first got the truck I was running Mobil 1 TDT and regens were more around 300-400 miles. I then discovered the whole Ford F1 approval deal so I dumped the M1. Switching to Delo XLE SB 15W40 it seemed to immediately regen more often. Maybe it is just coincidence, I don’t know.
I don’t drive like a grandpa and make sure to blow the cobwebs out pretty regularly.

 

The reason I believe my regens go out as far as they do, is the fact where I live in the hills south of Buffalo, so my truck gets hot climbing the hills coming back home. One way is 18 miles. The soot builds faster on the way in since altitude is dropping and the EGTs are not as hot.

Pretty much all diesel sold in the US most likely has some biodiesel in it, it can be between B2 to B5 and not be marked as such on the pump. I buy at the same carwash chain here in WNY and they seem to have good, clean diesel. I run 10w30 as I just daily drive mine. Have used mostly the MC 10w30 Super duty oil, but have now been using T4 and T5 10w30. I started using Planet Safe Lubricants Oil and Gear additive since I use their AiM lube that works really well around the house. The first time I used, the engine sounded quieter than it normally does and my UOAs turned out fine with it in there. 1 oz treats 1 gallon. I added 4 oz this recent change because I know that truck contains 17 qts or so (if you want I can post the Flying Wrenches video that shows this), but only 13 qts drain out. I am now running 15.5 qts (see the 6.7 higher capacity dipstick thread). What sold my on their oil treatment was the testing they did with dino standard 10w30 oil and the reduction in the wear scar ratings. I'm going to put it in rear diff when I change the fluid this summer.

I let the truck tell me when to change the oil (by 7.4k miles), I run a FS2500 bypass filter and every 3rd oil change, change the FD4615 fuel filter set.

As to additive, I've used K100D since about new every tank. I started using Pittsburgh Power's Max Mileage FBC (fuel borne catalyst) about two years ago. Now I use it combined with new Flashpoint additive, which adds more cetane than the K100D does and is similar to K100D in function, in a 16 oz bottle in a 10 oz FP and 6 oz MM.

Opinions on this stuff is different and varied. As long as the truck is being maintained with regular oil changes and fuel filter changes, at their comfortable intervals, that's what counts.

Some use no fuel additives, some use them sometimes and some like me use them all the time... opinions, you know, every body got one, right?

I run a Banks Pedal Monster, Banks Derringer tuner and two iDash units to monitor things like primary fuel pressure before the CP4 HPFP, EGT1 and EGT4, fuel tank level %, regen status and other things.

I also peg it every once in awhile as well. But normally, I'm parked in right lane at 65, 66 mph watching all the jack ***** bumper to bumper at 70 to 75 or so on the drive in to work.

Have a good one...

 

Could you guys help a dummy out? I have ForScan lite on my iPad and I can't figure out how to read DPF status. I can force a manual regen, according to the options. It does ask if my dongle has a switch on it and mine does not. Is DPF status one of the things I can't read without that dongle with a switch on it? Or am I just missing something?

 

There's a FORscan thread here in the 6.7 section.

​​​​​Plus @ZooDad is the resident Forscan expert...

 

I've look high and low and am not finding anything. Sometimes, it's right in front of me and I can't see it. I can see how to force a regen but cannot find what my filter status is.
