Not likely an immediate failure. More like a slow miserable death if the oil is continuously diluted with fuel.

Automatic Regen too often

so picked up the 2024 ram 3500 HO last week. 700 miles in and the dpf guage hasnt even moved. its sat on 0 since the day i picked it up. i did add archoil the day i picked it up and have run it through 2 tanks.
Well….i almost made it 24 hours on this last cycle. Missed it by minutes. I got in a bind and had to use my truck to take my daughter to cheerleading practice, which consists of about 20-25 minutes of back road and city driving. Highly congested area where speeds stay below 40 mph. Would have made the 24 hour mark if it hadn’t been for the slow driving.
This cycle: 9/13/24
905 miles since last cycle finished
23 engine hours since last cycle finished
Average speed in this cycle was 40.39mph
Previous cycle: 8/22/24
382 miles since previous cycle
10 engine hours since previous cycle finished
Average speed in this cycle was 40.5mph
Both cycles saw zero towing and zero loaded operation. Predominantly highway travel, and almost identical daily drive cycles. The only factor that was significantly different was temperature. Morning commute temperatures for the time period between the 8-22 and 9-13 regen cycles were significantly lower than the previous few months. Temps usually about 40-45°F in the morning. Aside from that everything else was the mostly identical.
My DPF % REG after this last cycle finished was 5% upon restart, indicating a pretty good clean out of the DPF. I went back to the 1oz per 10 gallon rate of Archoil AR6500. Going to see how it does this time around. I’ll be due for the AR6400D in another cycle or two if things stay around the 900-1000 mile mark

If I remember right, I think I was at about 10k before I started to see soot load registering. I just assumed it was because the DPF filter had not seen much use / soot buildup. I hadn’t used any archoil until about 20k, curious to see how it effects soot buildup on a new DPF.

yea, figured just use it from day one and see how she works out. curious to see what the diff is between the SO and HO soot loads. im going to order the edge insight 3 or whatever this week and see what the actual numbers are.
I noticed something similar on my commute this morning, 74 degrees with humidity at 78% which is real nice weather here on the Gulfcoast. Normally once I jump on the interstate, in about a few miles, my DPF filter level will rise. However this morning with the low relative humidity and cooler temperatures, it did not. Supposed to have cooler temperatures the next few days, will see if the trend in the morning continues. Am currently running archoil daily @ 2oz/10gal, once this tank of gas is at 1/4, I’m gonna use the cleaner.
My “magic number” seems to be approximately 50°F and lower. I get noticeable passive regeneration in that temperature range. 51°F to about 65°F it seems to be more of a very slow build. Above 65°F and soot loading gets progressively more pronounced as the temps go up.
Without a load, I presume?

Yep no load. Also towing around town light to light aggravates it as well.

No clue what is going on with my truck. Drove 21 miles yesterday non-stop on the highway at 75mph. Truck DPF evic was at 0 at the start, and by the time I parked it was at 48%. I wish ram/stellantis gave 2 $hits about our issues. About to hook to a trailer to see if I can work it back down.....
It shouldn't take crap like this for these trucks to function. I have 35" tires, a 350lb leer fiberglass shell on my bed, and a decked system in there. 500 lbs in the bed, plus bigger and heavier tires. My truck is working hard enough...

I am not running one. Honestly never noticed a dead pedal yet

Ran one for about a week but the way I learned to roll the throttle on a diesel it was pointless. Took it back out as it was wasted money.

i put the one i had in the new 3500 and it changed the truck 100% for me. the way the throttle comes on its really wild. granted i have the high output, but still..... it broke loose on me this morning on the interstate when i was merging into traffic. i have to turn it down when i leave work today. i like the power but i dont need it hitting that hard.
Not running one in mine.
100% stock

Not running one in mine. 100% stock. No regen issues to date.

I think it comes down to driving styles really. I can get the truck to do what i want when its not in the shop lol. i just did not see and plus side to doing it no Power gain just tricking the computer on throttle position.
Two questions:
Does anyone know how many miles between regens will throw a CEL?
Secondly, what temp at EGT3 is good for passive regen?
As others have said and have told me in this thread, 70-75 is an ideal speed and creates enough work for the engine causing the EGTs to get high enough for passive regen but 60 mph is the speed limit where I am and I’m not going to constantly go over the limit by that much. The EGTs have a good jump going from 60 mph to 70 mph but I still think it’s insane to have to go 10 over the highway limit for the filter to clear out.

Cant answer the first 2 questions but I can say since I started using Archoil I can get passive regens driving between 60-65 MPH...
