Diesel is the best engine option.

I love our 2021 Gladiator diesel. In my mind, there is no better engine option for the Gladiator than the Mortori diesel and ZF sourced transmission from Germany. I've owned Mercedes Benz, Audis and BMWs, and the diesel option elevates the Gladiator driving experience to a premium level, not unlike what you'd experience from the German brands. The 3.0 liter gas engine is fine, but if you seek a genuinely premium driving and offroading experience, spring for the diesel option, while it's still available.

Diesels used to be super-reliable engines. When new emission requirements came out (2005? 2006?) it ruined diesels. Manufacturers haven't been able to design a diesel for long-term reliability any longer. I understand they generally become very expensive to maintain around the 125K mark (this was from a fleet owner on a Sprinter forum). Remember the Volkswagon emissions scandal several years ago? They cheated the emissions requirements because they had to.

I had a 2006 sprinter, and it's emissions system was junk. Every couple of months I had to removed the EGR valve and clean it out, or else the sprinter would go into limp home mode. I definitely could not let it idle for long periods of time - that would gum up the EGR system rapidly.

The only diesels I use now are small ones on Kubota equipment. You couldn't pay me to take a diesel in a vehicle. Hope that changes some time, and they return to their former reliability. They are great when they work.

It's a given - like anything else at all in vehicles, tools, homes, locations "what I have is the very best, hands-down, nothing else is close"
To say otherwise is admitting there may be something better than what you have - that your choice could be giving you second thoughts.
So no matter what, "mine is always the very best, you can't beat what I have"
IF someone has a diesel, the others are all wimps and there's no possible reason to ever buy a gas powered vehicle.
Take any "what's best" with a grain of salt...........too many variables to say one engine is better for all owners.
Each has their reasons, their place, whatever. Gotta figure what you will be towing or hauling, if towing at all - where, how much, etc. and where you live among other factors.

Some of these get downright humorous.

I enjoy my diesel JLR enough that I’m going to order an Ecodiesel Gladiator this spring.

Subjective thread is subjective.

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

Here is my take:
Overheating/ limp mode, 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, bottoming out on the factory suspension.

Thankfully we have the option to chose.

EDIT: Added suspension issues.

ULSD and extra emmisions really killed diesels for me. The switch was 05-06.

Lower BTUs (Less energy), hygroscopic (Absorbs water), added chemicals to fight the first two, low lubricity.

They seem to be ok unless you work them hard.

Once you get out of warranty some of the repairs can be very expensive. Injector failure is not uncommon on any diesel.

To me it wasn't worth it.
