Has anybody discovered a DPF cleaner that goes in the fuel or DEF tanks that actually works? I can take it to a specialty shop and pay >$1k for a real cleaning but wish to find something more accessible and doesn’t keep my truck down and out for any length of time. It seems only the Euros have access to DPF in-tank cleaners and I wonder how much of it is snake oil.

Truck has 67k on the clock. I’m not highway driving like I used to. It goes into regen more than I like. No, I’m not trading it on a gasser.

Thanks in advance.

 

Since DEF is injected after the DPF nothing added to that is going to do any good. Additionally, I'd be hesitant to add anything to my DEF system.
The DPF is intended to remove/reduce particulate matter - soot - using very high heat so it seems to me the only way to reduce the need for that is to reduce the amount of soot produced by the combustion process and the only way to do that (without a lot of driving) would be to increase the burning efficiency of the fuel.
This leads me to two things:
1. Only use top tier fuel.
2. Cetane booster.

Now how dramatic a difference those two might make would be pure speculation on my part.

 

The pickup DEF/SCR is in front of the DPF, the Chassis cab is as you describe, so the systems are different in that an additive, if there is one, to DEF could clean the DPF, however, since it is soot, the best cleaning is heat.



Anyway, here is something you might want to look into.

Snake oil? Don't know, just found it myself.

 

What are you trying to accomplish? The DPF will self-clean by driving. If you want something more or potentially better, look into a manual, stationary regen using ForScan.

 

In my experience a static regen does a better job at cleaning. Also I'm not sure if a shop can clean it since the DPF and SCR are one unit and can't be separated.

 

There are dozens of DPF cleaning videos on YouTube. The majority of them that I have watched are from Europe. They have a lot of diesel powered passenger cars running around the cities, the DPF never gets a chance to get hot enough to properly regen, so they get good at cleaning the DPFs.

 

Napa sells some additives for the DPF, made by Lucas. You would have to ask for it as most likely won't be on the shelf.

Run it hard and hot is the best method.

 

I use Better Diesel Fuel Burn Catalyst. Most of my regens are at the 500 mile mark and they are finished fairly quick. Here's a thread from the 6.7L subforum on that product.

I used this in my 2017 with noticeable results. My '22 regens very quickly so I've never noticed a difference using it on my new one.

 

While I don't understand the concept of the DPF and how Ford calculates the DPF % full, it seems that the earlier models are more pessimistic and the newer models are more optimistic. It doesn't mean that the DPF isn't filling up though. I would rather pay a few bucks for a bottle of this stuff than have to replace the DPF. How you drive/use the truck can have a significant impact on the life of the DPF.

 

When ever it rains cats and dogs I take the truck for a good drive.

when I get back, there’s some grainy ash at the 6:00 position of the exhaust tips.

my theory is the the rain helps steam clean the exhuast.


just a theory.

 

when I bought it, I was pulling often. Nowadays, I do short trips and Dad Taxi work with little time at speed. Within two days of a weekend where I’d “blow it out,” daily driving in the burns makes it want to run a regen in Park. It’s a pain in the butt and a constant area of concern. I want fewer regents and am darn near ready to delete it if I can find a good shop to do it anymore. I can’t afford to replace the truck right now, so screw Biden.

 

Get Forscan, activate OCR and auto-regen inhibit and run your regen in your driveway. Then deactivate the auto-regen option and drive until your DPF reaches 100% then repeat.

 

I do manual regen when the distance driven is over 35 miles as it takes about 32 miles to do a full regen @ 60MPH. Just completed one yesterday. I use iDash to monitor the DPF levels, and wait until the dash says to regen then switch it on when either leaving for work or from work to home which is 60 miles one way. I figure this is better then short partial regens when it kicks on 5 miles from home.

 

Ford uses an absolute pressure sensor while Dodge and GM use differential pressure sensors.
So a single pressure sensor on the intake side of the screen vs. a pressure sensor on each side of the screen.
