    My 5.9 24v is DEF-free; 2001 didn't have any emissions. Love it. Smells like a diesel is supposed to smell! But that said...I'm not going to mess with my Eco. It works great the way it is. It's not "fast", and that's OK. If I need "fast" I get on my 370 lb motorcycle with 152hp at the rear tire. The Jeep isn't a tow monster. If I need to pull the enclosed car trailer...I grab the keys to the Cummins. It IS a fuel-efficient, luxurious, extremely capable 4x4 SUV that I think is actually very attractive. It's easy to drive, and it's dead-nuts reliable...so I'm not poking it with a stick.

      I thought you delete the EGR/cooler on those as soon as the warranty is up. Only 1/2 the soot and better mpg. My 03 cummins has nada emissions, built a boost elbow last weekend 38 psi the first try no adjustments. Cost 8 buck and 20 minutes.

      I'll be deleting my Cummins X15 performance series as soon as the warranty expires. Get the true 605HP and better MPG. It's a win,win.

          Once again.....

          THE ECODIESEL IS NOT A CUMMINS.

          They work just fine, if you leave them alone.

            Cool, I just saw most delete them after warranty. Never delt with DEF or EGRs on diesel, we had regen on our mowers that was a pain and were in the shop every other month because Kubota wouldn't give out the program to fix it.
            I realize the 3.0 eco is a robust platform used all over Europe, I just heard most delete.
            I'll stick with my 5.9

            ...and when they do, the problems start.

            I've owned mine for going on 8 years now (bought new in Dec. 2013); I speak from experience. I'm also a service advisor at a CDJR dealer; I speak from THAT experience, as well.

            It's your (wife's) Jeep, do as you wish....but if it were me, I'd leave it the hell alone. That's what I've done with mine, and aside from an EGR cooler replacement under warranty (pinhole leak, putting coolant into the exhaust, triggering frequent regen's), I have had zero issues in 80k miles. Customers who have left theirs alone...zero problems. Customers who monkey with them....have problems.

            As noted before, I also own a Cummins, and have for about a dozen years. Got it used, stock, its a 2001, no emissions, 24v with a 6 speed stick. The Cummins is known to respond well to modifications (and in the Ram, the ISB is massively de-tuned to begin with), and mine has some changes - Edge Comp box; Banks 4" turbo-back exhaust including downpipe and elbow, with a muffler; open element air filter; boost fooler on the MAP; boost valve (different orifice size on the nipple that goes from the elbow, to the wastegate reference line); mechanical fuel pump to replace the electric lift pump; boost gauge; EGT gauge; fuel pressure gauge. It is very happy, very torquey, and very efficient (20 mpg commuting, 17mpg pulling the car trailer). The Cummins...is not the Eco. And, the Eco is not the Cummins. Just because they drink the same fuel, doesn't mean the same changes have the same effect on both.

            The software on the Cummins is...quite a bit more forgiving. And again, the ISB in the Ram is SO de-tuned...it is almost begging for more. Most diesel motorhomes today? Run an ISB. With nearly double the HP and torque of what the put in the Ram. Why? So the ISB doesn't pretzel the frame of the Ram. Seriously. The Cummins ISL and ISX? Still the same basic architecture as the ISB...but even MORE power and torque. There's a TON of headroom in the Cummins platform, compared to the Ram pickup level. And, that's why it's such a successful package - it's barely breathing hard when you push it, in a Ram.

            The Eco software is much less forgiving, and the r&d to create the package, to meet requirements (both in the EU and the US) was extensive. They created a super-tight package....and it works. Banks has created the 630T crate motor from the VM Motori basic design...but about all it shares is the six bolt main girdle design...and the displacement. And, it comes with its OWN software. The hardware...must match the software. They have a Derringer programmer for the Eco, and some other bolt-on goodies, but mine's been so solid, so reliable, so capable...I just don't see the point.

            This, from a guy who's run 38psi through multiple 2.2 turbos back in the day (they weren't headgaskets, they were 10 second fuses); who had a 400hp smallblock B body station wagon that ran low 13s on street tires, pump gas, and a full interior and body; who currently owns a factory-turbocharged '90 Voyager minivan running 18psi boost (compared to 7psi stock), with a custom intercooler; and who has multiple hopped-up sportbikes to play with. I'm not "anti-modification" by any means, but the Ecodiesel just....works. And, it gets grumpy when you mess with it.

              I AM 100% on board with your advice! Leave the Eco-Diesel alone!!
              It's going to have to do towing duty if we need to tow, because the H2 Hummer has seen its best days in the rear view mirror, and sitting in my yard isn't doing it any good.
              Ultimately, I want a turbo diesel SUV, something with lots of interior room for the 3 big dogs and our 45 pound pig, so they have a good, observable space to share with us. We don't go anywhere together out of town without them, and the Jeep is probably too small for that anyway.
              Unfortunately, all I can think of that's:
              4 x 4
              Turbo diesel
              SUV
              is a Ford Excursion and not only are they around 15+ years old, people want a lot of money for them as I described.
              I'm open to Mopar/Cummins equipped options, but I'm afraid even the Mega Cab may not have enough room for the animals, but I can't think of anything else, unless there's a full size RAM van w/4 x 4 and the straight 6 Cummins?

                20210610_094938.jpg I like the thought of a diesel but it almost sounds like a bit of a pain in the ass. Anyways here's my 2015 2-door Sahara, I've had this thing since 2017 kind of impulse, it was at lease trade in that just came in, certified with warranty...... never had a problem, v6 gas 290 horse, coolest little thing to drive around. Never had a problem with it at all, still have the soft top in a sealed mopar box

                  No pain in the ass at all. Drive it, enjoy it. Fill the DEF once a year. Change the fuel filter every 15k miles. NO tuneups. NO plugs. NO coils.

                  Don't modify it.
                  Fill the tank.
                  Drive till nearly empty.
                  Repeat.

                    That's important as that mileage will be reached w/in 1 year. Thanks

                      Try to fuel at high volume places too, I've been burned before, I run a dual fuel filter, changed the first filter and was good to go.
                      Fleetgaurd in the stock location and a 2 micron fleetguard before the cp3, not sure what that 3.0 uses as a pressure pump.

                        Not a fan of them my self, I’ve always cleaned up other folks messes on them. I’ve replaced two, dealt with oil leaks in the front timing cover, antifreeze leaks from the egr cooler nipples / o rings, poor performance after flashing for pollution control problems with loss of mpg. The engine is made by VM motori. It was a Italian company, that was a joint venture by GM and Chrysler and the engines were built for passenger cars not trucks. I’ll admit the pollution control crap on these stinks like most new Diesel engines. IB suggested deleting all asap, be careful if you do that as you may wind up putting it all back on and paying a fine, depends on where you live as most communities are tired of folks rolling coal all the time. I agree with IB as the engines do not run that good and it’s very unreliable because if something fails your in limp mode, and calling a hook and the dealer. While I said I’m not a fan doesn’t mean I’m condemning it. Nice Jeep, I believe on this engine maintenance is key and don’t touch it or modify it . Chrysler did get in trouble with that engine and the EPA like VW did,but it was a smaller scale. The total failures,I was at a loss on why they did fail. My other buddy at the dealer has done many. It’s a car engine that wasn’t designed for use like a 6.7 so just know it does have limits. Keep good fuel in it change filters regularly , I’ve run power service or Howe’s in my stuff year round never had problems. Look for places that sell a ton of diesel so you don’t get funky fuel . Take care of it and use it for light duty truck and you’ll be fine. Good luck I wasn’t trying to bother you just telling you what I’ve dealt with and seen.

                          Yep I usually run Howes, but also rotate Stanadyne and Hotshots secret diesel extreme. Clean injectors are happy injectors.

                            For me to tell my wife where to buy diesel? She has already found a couple of places that have a good price, which may lead to higher volume? Would truck stops like T/A be a good choice? I'm not really sure what to look for, and I doubt she will go out of her way.
                            This I know from towing a light trailer with my van: the 3.6 V6 Pentastar is a good engine, and towed ok, but I thought the diesel would be better.

                            Any places you see big rigs. Pull in right by em.
                            I can fill my 35 gallon tank in like 15 seconds lol.
                            I used the Mobile in town and truck ran like shit till I changed the filter. I hope to get an airdog at some point. Not sure if there's one for that or a better fuel filter. Some guys just run a Baldwin vs a 2 filter setup. Enjoy, diesel is fun and different.

                              Oh anther thing lol if there isnt enough, there's B20, B10, and B100. I stay with B20 or fill the red at night and run lol, JK. B20 is probably fine for that, I rune B20 or whatever has the highest cetane, the use howes for lubricity and clean injectors.

                                Can't use a high speed nozzle on the Eco, it has the "street" filler neck (capless on my Grand). I quit using the high-speed on my Cummins, too - it filled too fast, I couldn't figure my MPG for the tank before it was done! And, at nearly 300k...lord only knows what sort of sludge is at the bottom of that tank, and I really don't want to a) mix it all up with my fuel, or b) drop the tank to clean it.

                                I'd avoid the bio-blends with the Eco. Check the manual to be safe, but I only run standard diesel...maybe 10% blend if I'm stuck. I'd NEVER put off-road in it. The Cummins...in a pinch, I'm sure it would run fine on heating oil! But not gonna chance it with the Eco.

                                I just run the stock filters (my Grand has two, for whatever reason; Ram Eco have one; not sure on the Gladiator), no issue. Not cheap filters, but still cheaper than a tuneup for a gasser!
