Gotcha, derating is the term I'm familiar with in regards to limiting engine power output.

Little more time this morning. What you describe is not acceptable from a new vehicle. What you described is also not the norm. I want to share info to help find the problem. That is why I use the forums.Hereās the problem! Both the new eco diesels 2020 JLURD and the 2021 JT Diesel are both de rating at low outside temps. They both canāt even hold the speed limit on roads in Idaho or in Utah. Neither vehicle is towing. Neither vehicle even has a tent or camping gear. They only have luggage for 3 to 4 and a cooler and food. Check the Gladiator forum and see all the disappointed persons trying to tow with there eco diesel. This not even including those people that are all shaking their heads because they thought they would be able to tow with their diesel and are not internet savvy or followers. Itās a problem Jeep needs to fix. I change my oil every 5000 needed or not. I donāt care if the oil will take the heat. I just want to drive on the road at the posted speed limit that the government set for me. Iām not expecting that out of the CJ. Come on, Iām driving in the year 2021
We donāt use just water. We use a 50/50 mix that with a 21 psi caps take the boil point to 286 degrees.Water boils at 212* so that 250* oil temps are driving up your coolant temps past 212*. Now don't forget that as you increase in elevation say like Denver at a mile high, boiling temp is actually going to drop close to 200*. So I don't ever want my oil temps over 220* under the absolute worst conditions. Not all summer long every time I hit a grade.
Rotella isn't approved for the Gen 3 engines. See the sticky for approved oil.Is Rotella actually approved for use in Gen 3 EcoDiesel?
I checked Shell website. Didnāt have any oils for EcoDiesel they recommended.
Also couldnāt find any actual specs for the oil other than the typical we are better statements with numberless charts.
Seems dealer techs don't read the spec. I know, shocker, right?Rotella isn't approved for the Gen 3 engines. See the sticky for approved oil.
Letās hope soon, got this thread on watch ! This is becoming a bigger headache. Especially since My jl is a rental car. Getting annoyed of complaints and bad reviews. Hoping that by doing an oil change will be my solution (doubt it).Just got home from visiting Bullet Proof Diesel. Great folks over there with a great deal of experience and capability. They spent an hour under the hood and under the vehicle photographing the engine, suspension, drivetrain layout. They have a very nice facility with plenty of R&D garage space as well as machining, fabrication, welding, and brazing capacity. To me, they look like the perfect sized organization to tackle this job, and I'm optimistic that they will be able to offer a solution for the JL and JT EcoDiesel application. They already offer EGR coolers for the Ram 1500 EcoDiesel, though that engine, despite being a Gen 3, is configured in a substantially different way than our Jeeps.
Presently, I'm not sure when I'll hear back from them, but I was assured they would get back to me eventually. They had lots of ideas, but packaging a solution is the challenge.
UPDATE @ 5:30 PM:
I just received an email from the Bullet Proof Diesel GM . . .
"We are procuring parts and I will be back in touch with updates periodically. If you have any questions or if there is anything we can ever do for you, don't hesitate to reach out . . . "

if the EGR is post DPF, wouldnāt the gas temp increase significantly if a Regen was occurring and thus increase the chance to overheat during a Regen?Yea this is one of the reasons a lot of VW TDI owners ran dynamic EGR tunes...get the engine to temp quicker and then shut it off. Little did they know, the factory tune was doing much the same lol. That said, VW wasnāt using post-DPF exhaust gases and as far as I can tell, the blended 3.0 exhaust gases are significantly cooler than many older EGR systems used so the effect regarding engine warming is likely less.
The EGR is pre and post-DPF.if the EGR is post DPF, wouldnāt the gas temp increase significantly if a Regen was occurring and thus increase the chance to overheat during a Regen?
