Deisel problem question...

I have a 2017 Ram 2500 Cummins diesel (50k miles - well serviced).
Was headed to the dealer this morning to change oil. Stopped to fill up and then headed to dealer when it started running really rough and then slowed to about 10 mph and would not go faster. Check exhaust system warning came on. Got to dealer a mile later and there was plenty of white smoke coming from beneath truck. Dealer got a fire extiguisher and put out flames coming from cat converter. He said it was glowing hot. He said the transmission wiring harness and other stuff was toast. Will not hear from them till Monday.
Anyone have any ideas what went wrong?

In before “you bought a Ram”.
No idea, but sorry to hear it.

Yeah you bought a dodge

You're supposed to fill it with diesel. 
Posted on 8/17/19 at 8:45 pm to Tigerinthewoods
On bright side, you were going 10mph faster than most gmc and Chevrolet’s out there

That was my first thought. If he put gas in it he should go to church tomorrow because he's lucky to be alive!

Sounds like your dpf is plugged and it was attempting to regen.
Several ways this can happen with that many miles. One is frequently taking short trips with the truck and never allowing it to fully regen. Another is to use non-synthetic oil. The other ways involve failures that put the engine in constant regen, but this definitely sounds like a plugged DPF

Not sure who told you that, but that's crap. The base stock used in an engine oil is immaterial. What is important is that you put in the properly spec'd API recommended oil (as recommended by the engine manufacturer). A properly spec'd API oil can be a dino (non synthetic) or synthetic oil.
Using the improper spec'd API oil can be detrimental to a DPF.
Once again, the base stock (what dictates whether it's a synthetic of not), whether it be a Group III or higher base stock doesn't matter to the DPF.
The detergent pack (again, proper API spec) in an oil is what can potentially plug or cause more frequent regens to your DPF.
If your lose your DPF and reprogram, you can run any API spec diesel oil you want. I'd recommend a CI-4+ oil with no DPF.
tl;dr version: run a non-synthetic of synthetic oil, but ensure that you running the proper API spec. Look on the back of the oil container to verify it matches with what the engine manufacturer recommends.

No, it isnt.
Non-combustable metals present in non-synthetic oils are what permanently and rapidly plugs them.

You should check out some VOA's and UOA's of non-synthetic and synthetic oils and get back with us.
ALL oils come with non combustible metals in them (in trace amounts) from the factory. See below virgin oil samples of Delvac non-syn and Amsoil synthetic.
What do you think happens during combustion and the natural wear from engines? Yeah, more metals are picked up and a used oil analysis will verify that also.
Again, I'm not sure who told you that a non-synthetic oil plugs DPF's moreso than a synthetic oil. That's incorrect. Get the correct API spec oil and you'll be fine.

Ok, not using a hyper-refined oil of the appropriate spec will cause ash loading.
Happy now?
For most diesel guys the only oil decision they make is rotella or synthetic. Rotella T3 is cheap, the others are not. Rotella goes in, DPF gets ash loaded, DPF needs replacing.

Rotella t3 is dog shite oil

It works fine for older mechanical diesels. I use it in a bunch of my air cooled stuff as well like the pressure washer and generator since I have gallons of this shite laying around

Ram 2500 is not a dodge

Still produced by Fiat Chrysler. Just a different name badge

That IS correct. If you are putting an improperly API spec'd oil in a diesel with a DPF, then yes, you are asking for trouble.

If you have metals from your engine oil clogging your DPF system, then you have bigger problems than a plugged DPF.

Not necessarily. The engine itself will work fine on just about any oil. All of the bullshite from the wrong oil can plug it up though

That actually goes along with my point.
I have 3 trucks with DPF systems. I use mobil del-vac in all of them and service them religiously every 25,000 miles.
Two of them are higher mileage, around 550,000 miles and have always used some oil between services, both also have occasional DPF problems.
The truck that I drive, just tripped 400,000 miles. In 140,000 miles that I have driven it, it has yet to use a drop of oil. It also hasn't had an exhaust filter problem and regens exactly like it is supposed to. like clockwork.
So what I am saying: If it was cheaper to fix the oil consumption issues, it would probably solve the DPF issues too. As it is though, we just keep 'em on the road, best as we can.
