Not diesel I suppose.

Stock Rubicon 3.0L - Mixed street/hwy - 22.7-23.0 nearing 1000 miles on the odo. Have a soft top but steel bumper - end-caps removed.

Hello @Clayton Off Road, I have a diesel JT model with a build date of August 2022. I don't have the bottoming issue (so far) as I guess my JT has that TSB addressed from the factory itself. But I want to address the rake. In my case, do I need the shock extenders with the updated factory...

ESS is OK for gasoline but not for diesel turbo. I noticed ESS stops the engine even after driving hard on a highway and coming to a stoplight after taking the exit. Turbo temps still show excess of 500F and engine still shuts off.

Anyone notice any difference in soot accumulation before and after using any HotShots additive, whether it be EDT or just LX4? Or any change in regen frequency?

Noticed that EDT and Winter+EDT have CA Prop 65 Cancer warning (if anyone cares but nevertheless...). The LX4 does not have the Prop 65 warning, at least from the label pictures I saw online. My LX4 is arriving tomorrow. I will start the LX4 regimen when I fill up next by this weekend.

When you shut off the 3.0L, there is a buzzing sound under the hood that lasts approximately 3 minutes. Some Jeeps are louder than others, but parked inside the garage, it is very prominent. I was told that is a pump sound of fuel being returned back. If that is the case, and there is some...

Slightly off topic but do you have the 37s on stock 3.73s gear ratio or did you regear?

That is actually active regen. Passive regen occurs at any time when DPF is hot enough but very incrementally reduces the soot.

That is what I have. And since I have a premium twill soft top, the Bestop Twill is an exact match and looks like a factory install.

Makes sense.

Thanks. I have a concern on my 2022 JTRD produced in Aug 22 (though it was made 3 months after the suspect fuel pumps were last used) but a little bit nervous on how HotShots or any other brand may impact the warranty or have any unknown side effect. :)

Since after how many miles on the odometer you have been using it? And you don't see any negative impact on emissions system?

Hotshots EDT I saw on Amazon has LX4 in it. Are you using just the LX4 or the EDT with LX4?

Mopar recommends it in the manual only under cold temperature operation. I didn't see anywhere else in the manual that it recommends it for any other purpose. In fact the manual says that additives are not necessary (though it doesn't prohibit it).

Thanks. Results favor the additives on CP4 health.

Question: If fuel additives like Hotshots EDT help in prolonging the life of CP4, why is Stellantis not recommending use of Mopar or any equivalent to add lubricity to the fuel? Also, among those whose fuel pumps failed, were any of them using such fuel additives?

You mean in between active regens. Passive Regen - Happens when you are driving and soot is burnt incrementally in the DPF if is at a certain high temperature. Active Regen - When soot level reaches 80% in the DPF, fuel is injected in the exhaust to actively burn the soot. In my experience, and...

Happens when too many active regens are interrupted and DPF soot level is high. Prevents you from taking to a dealership to do a forced regen. Having a Scangauge helps. You know how much is a soot level and whether you are in an active regen or not. An active regen usually does not take more...

It is the oil that needs to warm up. Oil does not warm up by idling. Quickest way to warm up the oil in a cold start situation is to idle for 30-50 seconds for the idle rpm to settle down below 1k, drive gently for a few minutes till oil temps get to at least 150-176f, and then you are good to...
