After the update I was getting regeneration warnings once a week, even after driving 200 miles on the highway. A little over a month ago, I was having an oil change at my mechanic who is a diesel specialist which services, busses, sprinter van fleet, etc. I brought this up with him and he said try using a diesel fuel additive every other gas tank or so. Well, I have not had a regeneration warning (drive at highways speeds) since. Just curious if anyone has been using fuel additives and how are your regens. Non tuned owners

Can you guys tell me about. " PSD Diesel Kleen and Cetane boost every other tankful "
What is it supposed to do? Does it decrease soot. Obvious by the name it raises the Cetane level. Does it impact our warranty at all. Thanks

From what I read it helps with the lubrication of the fuel, so I'm assuming it somehow reduces the soot.

Additives have little to no influence as to when and if your vehicle will regen, nor will it lengthen the distance between them. They also raise your cost per mile of ownership... You may say that's not much, but 5-10.00 here and there over the lifetime of ownership adds up, as out of pocket costs. Never have used additives (other than Anti Gel..) in any diesel I've owned, and my RAM is 16 yrs old with mega miles on it. Runs perfectly...
It certainly doesn't HURT anything, But it's an added expense that just isn't "Medically" necessary... Buy fresh fuel, change your fuel filters reasonably often, and keep moving....JMHO

Use Diesel Clean in my diesel motorhome, the Aqua-Hot diesel water heater uses fuel from the main tank and has to (well should be) disassembled and main burner cleaned once a year. The burner tube and injector tip remained soot free. There was a yellowish looking coating on the injector tip and burner tube but little to no soot.

Grant it this is not a diesel engine, but it is a diesel burner with a pressurized injector tip that to some degree ,mirrors a diesel engine. non of the service centers that performed the annual maintenance on the Aqua-Hot system had ever seen a burner tube or injector tip that was so clean.

I know the EcoDiesel has had issues with the Bosh fuel pump failing due to internal cavitation, I am hopping the varnish looking coating that Diesel Clean leaves will slow or stop any possible internal cavitation in the fuel pump

I think that Europe uses research number for cetane while the US uses both research and measured. That does cause a difference in readings with the US always being lower...

I had my Bosh fuel pump fail at 27k. Under warrantee they replaced the entire fuel system including tank. It would have cost $13k according to FCA.

Update: It has been 8 tank fill ups, with "deisel clean additive" every other tank, and have not experienced one regen notification.

If you're running the stock ECM tune, you're having an active regen every 75-200mi whether you see a dash message or not. If you really want to see if a fuel additive is making a difference on regen frequency, use an app like Torque Pro to monitor every regen. Log the mileage that it occurs.

I occasionally use a fuel additive only for the added lubricity for the HPFP. I run 5-20% biodiesel for the same reason. I'm more worried about longevity of the fuel pump.

What fuel additive do you use? Your correct, the HPFP issue is a major concern.
I did confirm the Ecodiesel does use the Bosch CP 4.2 HPFP that has been failing in the Ford, GMC, and Ram diesels.
Bad design. That's 1 of the reasons I bought the Maximum Care extended warranty, 8 year 120K miles when I bought my 2015 Limited.
If the HPFP destructs, it could be a $8000 fix. Possibly more.
Haven't noticed to much talk on this forum about that happening.

Jeep at the dealer today for a P24AE code that shown up twice in the last month.
Rep said there is a revision to the AEM coming, but they don't have it yet.

My Jeep is completely stock. I only started using 'diesel-clean' because my mechanic said it was a good idea to use it every other tank. I have not had a "regen message" in almost 6,000 miles.
I'm worried about the fuel pump too. Mine went out at 27k, had the entire fuel system replaced, and FCA said it would have cost $13k when they were trying to sell me an extended warrantee

I was running Diesel Kleen, now running HotShots Diesel Extreme. Bottle says every 6k or 8k, I forget.

Just got back from Colorado where I noticed the diesel at Kum'n'Go already has Diesel Extreme added in.

I had several "keep driving" notices in the first two weeks after AEM. With an OBD reader, I monitored regen status. After 3-4 weeks, I saw fewer EVIC regen notices, but, as Bounty and others have stated, the regens continue. It seems the ECM may "learn" the new normal after AEM and perhaps adjusted notifications accordingly. The OBD reader indicated significant reduction in miles between regens after AEM. My average went from 200-275 miles before AEM to 63-112 miles after AEM in mixed driving. I have never used an additive.

My stock 2014 EcoDiesel GC has been relatively trouble free before AEM with only the SCR as significant recall - No other mechanical or engine issues. It WAS a joy to drive for 95K miles, but the AEM update is a disaster and the risk of expensive engine/emission related repairs seem almost inevitable. I put 250K miles on a 2001 V8 Durango, and I thought surely I would get at least that out of the EcoDiesel. Without GDE, I am considering a move to the Hemi if not completely away from FCA.

AEM done on 5-13-19. Since then had a lot more regens per my Scan Gauge II.

After throwing 2 P24AE codes within 150 miles, and in the last month, I took it to the dealer a couple of days ago.

They replaced the particulate filter sensor. We'll see if that squares away the frequent regens and codes.
