I follow your thread but haven’t commented. I noticed an error in your thinking process which I wanted to point out. Your regen cycles mile interval will decrease when towing. You had a good point about higher EGTs but you did not account for the extra soot levels because of your engine working harder. For example, look at a deleted truck that puffs black smoke. You stomp on the go peddle and the amount of smoke drastically increases. Keep up the good work. 👍

I should also mention my last few experiences with regens since I’ve done some long drives. My last 2 1000km drives I went into regen every 800km on the nose. My first regen process only lasted 24km (12min) 100% to zero. A day later, On my way back, my next regen cycle lasted 58km (29min) 100-0. I’m starting to think that the DPF % screen doesn’t accurately portray how full the filter is. In my situation, because I do mostly all highway driving right now, my DPF % screen hits 100% and starts a regen cycle at exactly 800km. Exactly!!! I know this is the factory preset distance for an active regen to kick in but you would think that the filter would fill up faster or slower due to certain driving conditions like wind and grades but nope, 800km and it regens. I must state that my drives are over 800km long with maybe one fuel stop and 2 towns to slow down through so I get a good test period. This has been tested about 10 times now and exactly 800km an active regen starts. There are more factors involved than just the actual filter being “100%” full. See where I’m going with this. I have forscan but have not monitored the soot levels while doing these trips. Just giving you my experience so you can adjust or skew your data or perspective as needed. Thanks man.

Delete the truck and you won't have to worry about all the regen non-sense!

100% on the dash is no where near a completely full filter and you wouldn't want it to be. If that were the case, your exhaust would basically be clogged everytime a regen started. That would be very good for performance. I've heard it a few different ways, but I think you're only at maybe a third of the filter capacity when a regen is triggered.

Deleting is not a viable option for everyone @rcg270 .

I have started reading up on Fuel Born Catalysts (FBC) since you brought it up. I know there are a bunch of fuel additives to run out there, but the more I look I find that none of them claim the lower the temp that soot will burn up. I understand that they are not making that claim because that's not the point of their product. I am also finding that it is mainly used on large trucks, as in Semis, I can't find any real world results on pick-ups like I can for the big rigs.

Do you plan on running the FBC exclusively? Or will you stack it with another additive. Personally I use Archoil, but could I stack this to get the added benefit of the lower EGT range for soot burn off? Or do you (or anyone) believe this is too much dilution and not enough fuel. Thanks for any insight!

I don’t want to hijack OPs thread but just wanted to do a quick reply to this. You are correct. 100% just activated regen. The truck can get up to 300% which is completely full. I’ve only seen a truck at 240% at the dealership.

If I was planning on keeping my truck for long term 7yr+, I would delete in a heartbeat. I mile my trucks out in about 4yrs so deleting is pointless for me. My last Dodge was deleted from day 1 and every oils change was clean oil draining out of the plug. Not black like a stock truck. Used to freak out the quick lube places. Lol

This is all good info and I will take it to the drawing board.
1. Harder working engine = more soot production. Still I hoped that the passive regen would have more of an impact but cant argue with data. I am curiuos about what the addition of an FBC will do.
2. I am curiuos. Do you use additives? Are your drives loaded or empty?

I plan on running the FBC along with my current additive mixture. I spoke to a rep at Opti-Lube and the said several of their customers run Opti-Lube along with an FBC. The FBC just arrived today so just to make sure I'll mix a little in a container along with fuel and Opti-Lube and let it sit over night. As far as the issue of dilution goes, the FBC from Better Diesel only requires 1 oz per 25 gal so there should be on problem. I have no experience with Archoil but there is a thread in the 11-16 forum that mentions additives and FBCs (some have mixed FBCs with their regular additive). You may have to read a few pages to get your answer but it has useful info along the way.

https://www.powerstroke.org/forum/ge...topics/1255474

And you're right about the research. There are some scientific journals that have some info but I am still in the process of going through some of them. And I do believe that FBCs are required in Europe but I have to verify that.

This is great information however I believe the truck is going to regen on a mileage count. I have not payed attention but mine will once a tank regardless of what I have been doing

My drives are are empty drives. No trailer and very minimal payload. I do not use additives either. The mileage max is definitely what is causing these regens in my long haul situations. In winter (-20 to -35C) I turned auto regen off for my 8 1600km trips to see if the truck would give me a DPF warning and it never did. I did that 1600km trip straight 4 times and broke it up into 2 days the remaining 4 times. However, when I reached my destination, the next morning I would turn auto regen back on and within a couple hundred km, an active regen would kick in. Again, no dash warning or OCR prompt came up. The DPF screen always read 0% in the winter due to the cold. Other users have reported the same 0 reading. I came to the conclusion that passive regeneration was helping due to the amount of KMs travelled and absolutely no warnings. When I drive in the summer, I will get the dash prompts when my filter supposedly reaches 100% but like stated in my previous post, I believe the DPF % screen is just trying to match my mileage count rather than how full the filter actually is. I also assume fords theory on the mileage count max for regens is it’s basically easier to clean a half full filter than one that’s completely full. They are trying to save a normal operator from themselves.
