Automatic Regen too often

I had to make a quick trip to Walmart for some grocery items this morning. Trip involves about 7 miles of two lane hwy (35-55 mph) and 7 miles of interstate (70 mph). DPF gauge was on 12.5% or 1/8 at the start. Right after I got on the interstate and accelerated up to 70 mph the gauge went back to zero. I’m 780 miles and 20 hours since the last regen and running the Archoil every tank additive. The additive does seem to make the truck passively regen easier than running without it. Just an update…..
 
There’s definitely a difference between the 6400D and the 6500. I saw no soot load on the gauge while running on the 6400D. Once I switched over to the 6500, I’ve seen the gauge go up as high as 37% (three notches) which is where it’s at now. Itll passive regen down with some highway travel in most instances, but it doesn’t stay as “clean” from what I can tell. I’ll need to run multiple tanks on the 6500 to see how it really does. There’s no question in my mind these two archoil products do indeed help. 700+ miles between regeneration wash utterly unobtainable for the past four cycles.
 
Haven't been able to get into the dealer, but I needed to tow today so I hooked up to the cargo trailer and sent it. It got total crap MPG on both fuel and DEF, but it did alright based on temps/pressures. Boost/Drive pressure is all good so I highly doubt I've got a boost leak or something turbo related and my exhaust brake still works great. Exhaust is starting to smell a bit more like a diesel so I imagine my DPF is cracked - Don't have the PM sensor recall so I'd imagine I'd be throwing the code if I did. On the upside the DPF showed empty lol and with a load she kept the damned EGR closed most of the time.

I'm gonna try calling the next nearest dealer next week to see if they've got time to knock out my open recalls and take it from there. That being said just about every 6.7 in that employee parking lot is deleted so I think I know what they're gonna suggest I do about it long term lol.

So, is the overall fuel quality buns or is it the tuning? My passive regen I feel could work better with the amount of highway it sees. Im typically 12 hours 4-600 miles between. 6400d in this tank, see what she does.

That’s how mine was doing before the Archoil treatment. It did some serious cleaning on my truck leaving a light gray soot in the exhaust pipe which has now been blown out. They claim not only does it clean but also reduces the required temperature to promote passive regening. I’ll be interested to hear what your results are after trying it.
I had an active regen 40 miles after adding the 6400D.

You should run an untreated tank to see if it’s a fluke.

My plan right now is to continue dosing with the 6500 over the next few fill-ups and continue monitoring / documenting results. I’ll be interested to see if the regeneration cycles / mileage between / and hours between remain roughly consistent, or will I start to see a degradation again. I’ll be honest I don’t relish the idea of not adding the archoil now that I’ve seen the successes so far.

Happy to report have the last regen everything is working normal. Passive regeneration is back even with some idle time. Difference is shell fuel vs Kroger.

Well there you go, I would not have thought there would be lower quality fuel in the US.
In OZ if you are a independent service station owner ( Johnnys fish and chips and diesel and fuel one stop shop ) you can buy raw diesel or unblended diesel is a better description and you are suppose to buy the additives and mix it at your station as they fill the tanks, these guys dont mix the recommended ratio because they are profit orientated, the additives are expensive in concentrated form.
Personally I only use BP Ultimate diesel if not available then Shell V Power. In remote OZ there is then Ampoil and Mogas and always have my own diesel additives in the vehicle for peace of mind for the last two brands. I have a DPF vehicle thats been build in 2009 and never had a single DPF concern. Must add it does not have Adblue a bit early for that
Maybe thats the common similarity? So many things with todays modern diesel.

I’m not entirely sure but the dpf gauge is barely reading any soot at all since last regen and literally nothing has changed in my use. This would lead me to believe the fuel either made a big difference OR I interrupted a regen in my daily rush and it wasn’t able to be as effective. Both are possible but I’m just shoot to not have any issues. Any time the gauge reads soot and I go for a drive, it’s passive regens like it’s supposed to and did before so I find peace in that

This is where I stand after 795 miles and 20 engine hours since the last active regeneration cycle finished:View attachment 74705
The DPF gauge has been hanging out at that level for quite a while. Still on the archoil 6500 treated fuel.

Are you using the normal or performance dosage ? I would still take that as a win compared to what it was doing previously. Did you get a regen when you were running the 6400D ? I’m running the 6500D in mine and plan to continue using it until I use all that’s in the 40.6 oz container and then another dose of 6400D for another round.
I had been really mistreating my truck, making 4,5 mile trips and idling some and it finally jumped up to 1/8 but went back down doing a little interstate driving. 789 miles @ 20 hours since last regen and gauge on 0 now.

So this tank is treated with the 1oz per 10gal dose of 6500. I used the full bottle of 6400D on my previous tank. I’m fairly sure I put the 6400D in just before the truck ran a Regen cycle last time, so the 6400D would have been present when the Regen cycle occurred.
 
A small update to my experiment, for the last 3 tanks of fuel I've been running R99, the last two tanks were towing so I didn't have any soot build up, now driving unloaded I'm about 5 hours since the last regen and I'm two notches up on the gauge, I was hoping for better results using this fuel in regards to soot build up. It may be all in my head but it does seem to run better on this fuel compared to B5. I may have to try the archoil if it keeps building soot. This truck has never had a soot based regen and I'd like to keep it that way.

I would have expected far better performance from R99 in that regard, even when not towing. Only reinforces my belief that there’s still something wrong with these trucks in terms of soot loading. Whether that comes from faulty programming or hard parts has yet to be seen. My own truck is doing better on archoil than without, but it did fine on straight fuel for nearly half the year when it’s cooler here.
 
I would like to try the R99 and we supposedly have a refinery in our state that produces it but no retail outlet.
From what I’ve gathered after reading these 33 pages, some have mechanical issues, some is the drive type and just about all have trouble with increased ambient temperature. I guess it could be tune related with fuel quality going down because of the heat. You would think that the heat would help promote easier passive regen but with the fuel degradation because of the heat it’s the opposite. With the improvements the Archoil has shown, fuel quality and tune (or injection timing) which I believe varies with fuel quality. All theories. I think it has helped my truck getting more fresh air with the AGS slats being removed so that when or if they close it doesn’t pull air back through the radiator heating the intake air.
 
I think the comments on warmer weather having some effect on regen distance is correct. My last five distances between regens has gone from 1019, 1013, 910, 880, to yesterdays regen 856 miles. I live in rural northeastern AZ at the 7000 ft elevation, and our temps have been in the mid 80's to mid 90's so far. The area is several small rural towns, and most of my trips are about 25 miles round trip (45-50 mph) running errands several times a week. My truck is my only vehicle, so occasionally I'll drive a loop around the area that's about 140 miles, and then some camping trips pulling the toyhauler. I do see passive regens and full active regen at the 24hr, and usually takes 18-25 minutes at 65 mph. I've always been skeptical with the use of additives and although I'm not using Archoil, I think I may be getting the same results your seeing with my use of Stanadyne Performance Formula 8oz bottle per tank, I've been using it since my 2014 EcoDiesel and now my 2019 2500. I did experience a couple short regens after switching to the AB air filter, and then it went back to the normal 24hr clock after that. As far as the the trucks dash gauge it's confusing and I don't believe it's calibrated accurately as to the actual percentage levels. I use the Scangauge II which I bought and used in the EcoDiesel and now my 2500, and also bought the newer Scangauge III to try out. While driving I'll see the soot load percentage go up and down on the Scangauge, and that can be seen as well with the dash guage, but 0-100% on the dash gauge is way off. The photo below shows less than 50% on the dash gauge, and the scan gauge shows 96% at 22 hours and shortly after went into a full regen.

My truck will regen when it gets to where yours is on the DPF gauge.

Yes true, but you would think the dash gauge would show the 96% near the 100% mark! I think basically the dash gauge is not showing the actual activity of the levels raising and lowering, which it does a little but like most say it stays on 0. Those using the Banks, Sangauge and other monitors, are actually seeing the real time activity of the percentage levels increasing and decreasing while driving. The dash gauge gives one the impression that nothing is happening!

I know I've read it before but can you post a quick recap of how to remove the slats? I don't have my truck back 2 months at the dealer, and who knows how much longer. However when I get it back I have archoil 6400d and 6500 ready, and would also like to remove the top 3 or 4 slats knowing that hot air is significantly less dense. Therefore it stands to reason hot summer air further heated by a radiator is even less efficient.
