Diesel is the best engine option.

[staying_tuned]

My 6-y/o asked me why everyone doesn’t have a diesel gladiator. He (and his brothers) work on everything with me. This is our first diesel. I told him they have a tendency to burn down, suffer from horribly crippling emissions, sometimes freeze in what we’d consider chilly weather, can’t match the towing capabilities of their diesel brethren in the overall competitive landscape and require an additional fluid that we’ve never had to manage. Lastly, they typically sit longer when needing repair because it requires specialized training to work on them. Some folks, for good reason, find that unacceptable.

I don’t think most diesel owners go into this purchase blindly. Bottom line is, It all comes together in an incredible combination that for some is worth the risk.

Yup the torque is great and diesel is everywhere. In my area diesel is cheaper than regular so that's great for me. It's not just that the torque number is high, it's available from 1500rpm. The gasser's torque is 260 and at 4400rpm, like a sports car. I think my M makes its torque around that RPM.

The other thing is, why is everyone getting upset if one's opinion or preference is different than theirs? Are we all supposed to be robots? what the hell is wrong with people

Pentastar makes ~90% of peak torque from 1800 rpm to 6000 rpm. I don't have the chart in front of me but it's very flat. It's lower torque relative to the diesel, but it's actually a nice curve.

I don't think anyone is upset, but there are a lot of valid reasons why someone didn't think the diesel was the best option for them.

Exactly. Everybody is different. Just buy what you want. OP throws out an opinionated statement and everybody wants to disprove OP with their own personal opinions.

I bought diesel because I've had both in full size and based on MY past experience ..... I would never buy another gas truck. That's me. I have no desire for a 3.6 or even if offered .... a 5.7 or 6.4. No need.

I fully agree that the diesel has more complicated emissions equipment with potential future problems and I'm willing to take those chances.

Buy what you want. Enjoy what you want. Different strokes for different people. Enjoy your jeep.

Subjective thread is subjective.

I'm glad you are enjoying your diesel. They are not for me.

Here is my take:
Overheating, VM reliability woes, emissions, DEF, heavy, doesn't increase towing or payload, $4,000 buys a lot of gasoline, more expensive maintenance, 18 gallon tank, less diesel pumps, diesel is more expensive than 93 here.

Thankfully we have the option to chose.

Agree. Also - no manual transmission with a diesel.

I’ll take anyone for a ride in my 3.0, they’ll want one. Barely flog the pedal and the son of a bitch goes like a raped ape. DEF, as previously mentioned, is like 13$ every 3000 mi, diesel is ~the same as 87 near me and my mpg gauge is around 23 after running round town. On a recent trip gauge was showing 26.5 upon return of the 650 mi. 18 gal tank is a non issue, I traded my 12’ JK Call of Duty with the 3.6, down in TN 1000 mi away and had to stop 8 times on the way down, 4 on the way back with my diesel.

The smile per mile ratio is worth every penny of the $4000 premium, definitely the best upgrade on my build!

? Love a good read...

But how far do you have to drive for a diesel mechanic? What is the premium on diesel repairs versus gas? If someone had the 392 they would probably say that was the best engine for the Gladiator.
Or is this is the debate of gas versus electric and how easy is it to fix an electric car and cost to dispose of the battery?

We have a 5 year, 100,000 mile warranty. It's a non issue. IF if it needs repairs, it will be repaired. It's in the contract. Gas engines have a shorter warranty. Why would FCA want to lose money on warranty work if it is a bad engine? If there were truly problems with the design, the warranty would be 3/36 as with other engines/manufacturers

Short trips with the diesel can clog the dpf filter quickly. That's why a lot of people are saying they are not good for short drives since the truck needs to run a while to Regen the system. Short trips don't allow that to happen.

Not true. That's why there's a regen system, and also a low pressure EGR system once up to operating temp. So you've got clean air going back in which won't clog the DPF, and if the DPF does get clogged on it's normal schedule the regen system takes care of it seemlessly.

That is pretty standard for any diesel engine, I would read the warranty carefully many of the systems that are prone to failure are not included in the 100k 5 year warranty

In this thread: OP tells everyone who bought a gas JT they are stupid, people with gas JTs try to explain that there are a multitude of reasons why one might not want a diesel, and then everyone else flips out about "why are we fighting?"

Well, if you don't want people to fight you, don't start a conversation telling them how wrong they are. Especially when there are entire groups of people (mojaves, manuals, max tows) who don't even get the choice.

The only real Jeeps had the 4.0 inline 6 anyways, everyone's argument here is voided.

What thread are you reading lol?

I owned an EcoDiesel JL prior to purchasing my JT Mojave. The engine was vastly superior the 3.6 in all dimensions of performance, but from a NVH level the 3.6L offers the quieter ride, once you are off the on-ramp (lol). My wife and I both noticed this difference the second we got in the JT for the test drive, but I noticed the large drop in torque through the pedal.

I will say losing the 8HP75 was the greatest loss for me. In my use case, I don't "need" the diesel and much preferred the ride quality and overall package of the Mojave and decided I would be fine with the gasser. There are limited diesel stations in our area, at least with the right nozzle, so having to search for fuel was kind of an annoyance for me. For me though, the 850RE has an insane amount of rev hang once you get up to speed and just sits there revving to the sky for a few seconds. The 8HP75 never did this, and I have tried everything to get the 850RE to relearn by pulling the fuse a couple times over the past 4k miles. Likewise, I hear an odd whine come from the transmission that I never had with the "true" ZF transmission in the diesel.

I don't hate the 3.6L, I think it does fine for most cases. Is it fast, no. Does it need to be, not really. Living in central Michigan we don't have a need to drive excessively fast to keep up with traffic, and if conditions get to where I need to drive 85+ to keep up with traffic, I would prefer not to drive there and would take secondary roads and enjoy the drive more. For what it is, it's a solid powertrain with a nice flat torque curve. It's great that we live in an age where vehicles have so much power on tap through displacement or forced induction. This standard seems to have created an expectation that vehicles are "slow" if they don't hit 60 in 6 seconds or less.

All told, If Stellantis said they would allow the diesel in the Mojave I would be at the dealership same day to order. Not for the speed, but for the range, transmission change, and overall more relaxed powertrain.

Hell, I might even sit in a camping chair outside the door waiting for them to open.

If they had a diesel Mojave, I’d probably have gone that route, too.

someone else mentioned NVH a few posts back, I think the diesel is a quiet if not more so compared to gas. The extra insulation they add to diesels makes quite the difference.

This is very true. I have a 2015 and 2020 Ram 1500 EcoDiesel trucks. My 2015 has 100,000 miles and my 2020 has 13,000 miles. Both trucks have been awesome. I do a combination of short trips, long trips, and towing. The reward far outweighs the risk in my opinion. I'm now looking forward to getting either a Wrangler or Gladiator EcoDiesel.
