Just over the word safe
Oh ok, misunderstood ya. Mine hits the top of the safe mark with 3 gallons.
I’ve had my truck act like this before many times. What I’ve found, especially after installing the Banks iDash, is that the EGT’s post-turbo can actually be “cooler” when the truck is at operating temperature and is moving down the road in a low load, or no load scenario. Thats why it will, or it can, in some cases, start to fill the DPF back up in the manner you described. In the mornings, especially on cooler mornings, the truck will for a short time, actually have higher EGT’s when the engine is cold and is working a little harder to get things going. That short window usually affords some EGT’s high enough to achieve some passive regeneration. Coupled with the cooler, denser air, which makes the truck run better and cleaner. I think this is partly why my truck is able to easily achieve 800-1000 miles (24 engine hours) between regeneration Cycles in the winter months, but can’t make it more than 400-500 miles in the summer. Especially considering I plug my block heater in anytime nighttime temperatures drop below 40°F. My house is less than a minute from the highway on-ramp so my truck goes from 0 to 75+ mph in a very brief timeframe.
So just to update:
My truck completed its second active regeneration cycle since starting the archoil treatments. This time, the fuel was treated with a 2oz per 10 gallon dose of the 6500 fuel treatment. This time, the truck made it 24 engine hours and 1,062 miles since last cycle. There was approximately 500 miles of heavy interstate towing at the beginning of this period. 33,000 pound gross weight heading out loaded, 20,000 pound gross weight heading back unloaded. The remainder if the mileage in this period was conducted in an unloaded, not towing scenario in the same manner as my usual daily routine. Regen cycle lasted 20 minutes on the highway, unloaded, doing 75mph. DPF showed roughly 25% on the dash gauge when the cycle started and 0% after the cycle completed. Upon completion, I drove another 10 minutes to my destination and then shut the truck off for approximately 5 hours. When I started the truck up later that day, the % REG in the iDash was reading 11%.
Based on what I’ve experienced so far, I can confirm that Archoil does indeed help to increase time and mileage between active regeneration cycles. The 6400D fuel system cleaner appears to be far more potent than the 6500 fuel treatment. I suspect that, on the performance dose of 6500 and my routine driving cycles, I will still be seeing soot loading. It does seem to slow the accumulation down and affords slightly higher EGT’s, just not as good as the 6400D. I suppose more testing is in order.

Same. Even double dosing hasn't helped. Two regens a tank where I was regularly every other. Was 1 mpg better tho.
Update on my 19 limited. With the new differential pressure sensor I made it 215 miles before regening. This is my longest run with the truck. 100 miles of this was highway and the other 115miles intown. After the regen I had a 2g spike on the dpf with a 2 miles drive only. The truck is going to the dealership next week.

Well next timed regen under the belt since Archoil. Loving this so far. Perfect 24 hr, regen‘d in 20 minutes and next day started with DPF level at 18%! Usually would be at 37-42%.
Driving Time on Evic showed 1808, previous Regen was 1783, so that is 25 hours. Happy happy. Last regen was July 12th and this one was August 7th.

Another Archoil report: So far I'm shocked. I'm kind of a sceptic when it comes to additives as most of my past experiences have left me thinking "snake oil". My 19 HO with 112,000 miles has done many long highway trips and usually I'd notice no regens (other than 24hr) as long as my speeds were up. On a recent trip from Colorado to New York, I first noticed a couple of regens going and coming. I started noticing more frequent regens and they were taking longer, sometimes up to an hour to clear. I just did a trip from Colorado to Northern Saskatchewan 2800 miles, and had a couple more even running 76-80 mph. I ordered the 6400D and 6500 kit and on the first tank with the 6400D I'm noticing a significant difference.
I added the Archoil right after the last regen. The first full tank with the 6400D, my DPF gage quickly jumped to almost half full while driving around Denver doing a combo of city/highway. Before a half tank was consumed, my DPF gage had dropped to below 1/4. This morning I'm down to about a third of a tank remaining and my DPF has dropped to zero and has bounced from Zero to 1/8 to Zero again. I refilled and added 2 oz of 6500. I'm heading over the continental divide tomorrow on a 1000 mile trip but I'm optimistic that "Mighty Whitey" is back to acting normal on regens. I'll try to update when I get back.

FWIW, my most recent regen from (mostly) around town driving on my 2020 HO:
Last active regen (gauge ~45%) was 342 miles, @16 hours, (6 idle 10 drive).
I was forced to stop (work site visit) before regen completed.
It took approx 60 mins total (30/30) and 35 miles (15/20). The first half was city (boulevard) driving up to 55 or so, took and a few miles highway @70+, about 30 mins total. I detoured my destination and drove highway as long as I could afford timewise.
On my return trip home I took a different route that is 95% highway. Traffic was light so I was able to maintain higher speeds. Added more detour past the house and it finished after ~30 mins.
EGT temps post DPF hovered between 930-1080. On that higher end if I was running 85+
This tank has a normal treatment of XPD in it. I do have a bottle of Archoil 6500 but haven't really seen a need to use it yet. The truck does seem to be regen more often in the warm weather. Still only at 17K miles so this is either weather and/or normal and/or all you 2022 owners put a hex my truck.

You’re seeing consistent post-DPF EGT’s in the 900-1000 range with an unloaded truck, not towing!?
Oh ok sorry. I misunderstood what you were saying.
Has anyone had the China MAF fix their regen frequency? Everything I've been reading and @mbarber84 survey is saying that for the majority, it's not doing anything. My dealer was saying that it is.
I haven't popped a code yet but I go into regen an average of 339 miles and that's with mostly highway driving. I'll tow my TT a couple hundred miles and 15 miles later my DPF is up 12.5%. I'm currently awaiting my oil analysis result. It's my understanding that this won't be covered under warranty unless I have a code or the dealer can prove that something is faulty otherwise, I have to pay out of pocket including for the part that might not even solve the problem. I'm not one for throwing parts at an issue.
Also, for those that are using Archoil with the purpose of reducing regen frequency, are you using the Archoil out of warranty? I started using the standard dose and so far I haven't noticed a major difference. I'm contemplating using the performance dose. The reason I ask is because wouldn't it be better to fix a problem under warranty? If the Archoil does reduce regens wouldn't that possibly cover an underlying issue that otherwise wouldn't be a big enough issue to fix?

The last part of your post is what everyone has been trying to get done but evidently the dealers don’t know how to fix the problem or don’t care. The Archoil has allowed us to operate without having to visit the dealer. The 6400D is a lot stouter than the 6500 and most people run it first and then go to the 6500D. The 6500D is working for me but not as well as the 6400D did.
That's what I figured and also the reason why I started using it. I did the 6400 first and am a couple doses into the 6500. I'm toying with using the performance dose. Maybe some are just using it until they can trade in their truck. How frustrating.

Sharing this from someone who recently had a regen frequency issue. It was shared with me. They tried multiple things and ended up moving the ground wire for the DPF differential pressure sensor to a different location. The owner has the truck back and is driving it to see if things improve. So far it looks promising. Here’s the dialog that was shared with him (it’s between the technician and STAR). I’ve redacted any identities. Not saying this is the fix for every situation but definitely something to consider.

This is very interesting….is there any way we could get photos from this owner of what that ground wire to chassis solution looks like?
This is all he sent me. I can inquire as to more detailed pictures.
