Which JL engine are you most interested in?

[DanW]

I have a 2017 F250 6.7 diesel. This is one of the most powerful diesels offered to the common public. Over 400hp and over 900ft-lb of torque. When I first bought it, the sound brought a big smile on my face. It pulls a load nice and gets decent mileage. After a while the hype wears off. It is not a magic. People raise these things up to a level that is beyond realistic.

-At the end of the day, it is an engine with a turbo. No matter what they tell you, turbo lag still exists. It is annoying. You do not have power when you want it when at speed on the road. It is great at steady state power, but not sudden demands.
-The extra expense is annoying. My air filter cost $60. Oil changes are well over $100.
-DEF is not expensive but you guessed it....annoying. All so cities can reduce soot. I don’t live in the city and have to deal with this crap for no purpose. In the country, soot is not a significant impact.
-When the computer decides to do the burn in the particulate filter, it smells like you are burning electrical components and your gas mileage suffers as well.
-If you plan on keeping it a long time, you will be stressed about possible catastrophic costs that do not exist in NA gas engines.
-Diesel engines are no longer the hyper mileage units they used to be. They are no longer 300k+ engines like the old Cummins, Ford 7.2, or Mercedes engines.
-There will be a day when you are in a hurry, with the weight of the world on your mind. You will pull up to fill up your diesel jeep and fill the tank up with gas. Most people do it at some point. Hopefully you realize the mistake before you start it back up. If not, break out your checkbook and say goodbye to the family summer vacation. The cost will be enormous.

Cost one of the two primary reasons I decided not to get the diesel. It costs you up front, and it keeps costing, and the emissions tech has stolen the longevity advantage. The price per mile, especially if you factored in a rebuild, is staggeringly higher than the 3.6, whose first version has shown that 300,000 miles is a realistic expectation, with proper care. Everyone I know with a diesel has said the maintenance costs are high, and that the price of fuel at least in my area, negates the fuel economy advantage. I love the idea of 420lbs of torque, but it is a very high price to get it. Compared to a 3.6/manual, I predict the diesel will cost close to a $5,000 premium, up front. I'm guessing 3,500 for the engine, and 1,500 for the auto tranny. Not for me, sadly.

My 2nd reason is the manual transmission. I'll be shocked if they even offer one with the diesel. Why would they? Autos work so well with them, and sales volume would be even less than it is with the 3.6.

I know folks will enjoy that 3.0 diesel, but people will kid themselves into thinking there is an economic advantage, The only advantages will be cost and range.

DEF isn’t for soot, it’s for NOx, the DPF filter is for soot.

Which sounds like yet another maintenance item. The more I learn about the diesel, the more dollar $igns dance in my head.

Initially I have been very interested in the 3.0 diesel having lived with Diesels for many years I have become accustomed to the huge torque and fuel efficiencies. Of late the EPA has castrated the diesel market by demanding EGR equipment to be installed. This while works very well on Gasoline fueled vehicles is extraordinarily detrimental to Diesel fueled machines. The EGR adds unburned fuel back into the intake, this unburned fuel is a form of carbon dust corrosive and abrasive and contributes to a decrease in fuel efficiency and longevity. While there are aftermarket organization that can by-pass this useless piece of equipment when will it be available for this "new" engine? Also if the EPA fuel mileage figures are remotely correct, the additional cost for the diesel will be hard to recoup of the life of the engine. If indeed it is only a few MPG better than the gas and you do not tow anything The 3.6 is a better bet in this current climate. If a organization is available and willing to "re-tune the 3.0" to provide longevity Than I am in.

At a certain point, loss of traction will defeat horsepower. 200 horsepower per wheel won't do you much good if your tires are no longer gripping the ground surface. I haven't seen too many occurrences lately where a 2-dr JK's engine has stalled because it didn't have the power to keep climbing. But I have seen a lot of times where even a 35-37 inch tire just burns rubber or spits out ground debris because the incline is too steep and/or the ground material is slick or crumbling. Would a 2,000 hp engine in a JK really let you climb an 80 degree slope?

6.4 V8 will fit perfectly for this JL .... but, as i am from belgium ( you know belgium? this tiny non sense country, AKA taxes land, AKA Rats hole for our capital Brussels ;-) i would says that for us 2.0 is interesting about taxes but not about gas price ( 1.6 € for 1 liter ), 3.0 Diesel is interesting regarding diesel price and not so bad regarding taxes but definitely out of the race regarding service repair costs ( we are in EU guys.... only 2 years warranty and only if you are a private owner... if its professional ... just one year) and 3.6 is just nice because of the V6..... hopefully we have some opportunities as transforming the cars in light truck ( suppressing rear seats ) and LPG price is at a real good cheap price.... then for me it will be a 3,6 V6 with a conversion in mind if i find a way to homologate this conversion in V8

Everyone has their own rationalization of why their choice is better than your choice.

Meh.

Still getting the diesel as it'll haul my stuff better. Still debating the truck vs. unlimited.

You mean torque and range?

This exactly. ^^^^^

20 years ago, diesel was awesome. Fuel was cheap, MPGs were very high, and the engines would last forever. Today, none of those things are true. It's sad that we're just now getting more diesel options because 20 years ago it would have really been worth it.

I've owned a couple of diesel Jeeps. When I had to pay $110 for a thermostat it scared me a little. When I had to do a $1,000 timing belt change it scared me a lot. When I started hearing of guys dropping $7,000 for head work I said that's enough and sold them.

Which engine(s) had these issues?

 

[Tell3131]

I missed the actual numbers of the V6. What are they?

Sure ;-) my pleasure .... what kind of waffles??? Brussels waffles or Liege waffles?
i'm gonna be in LA for LA AutoShow to see the JL in december and in Vegas in January for Shot Show... Choose your date to pick up

There are ways to lower your costs with any type of engine especially a diesel; it’s call do it yourself. Yes fuel filters have to be regularly changed; you save by changing it yourself.

I’ve never in all of my life had someone do my own oil changes, except once when it was a free first time new car change. First of all I don’t trust any dealer Tech. This first time change the Tech over filled by a quart; that was the last time I ever stepped a foot into that dealer service shop.

But that’s the same for all 3, the difference is the required components of that DIY maintenance and the frequency schedule.

i'm pretty sure that Diesel isn't new in USA but here in EU we are definitely champs about this kind of Engine.
truth is , new diesel engines are definitely too much sophisticated and they try always to do something clean with a dirty base.
so of course torque is impressive, of course consumption seems low, and if you chose something with at least 6 cylinders you will have something smooth and giving real driving pleasure, if you like low revs.

in fact diesel sounds to be something like heaven, and it's almost true in the beginning.

but they are lot of troubles and shittty things that constructors doesn't says ..... like

using a diesel to make short distances.... seems ok but you will definitely putt a amazing mess in your exhaust system ( particle filter, regeneration process, etc etc ) and some day... engine failure appears and that cost a looooot to change those parts.

that smell like shit and if you have this product on your clothes or on your shoes ... not good for inside the car

part are more expansive (injectors prices are insane and if something goes wrong ... OMG be prepared to have a serious bank account (for example ... 9000$ to change 6 injectors, 2 filters, 2 diesel pumps and 1 high pressure ramp on a 2.7 V6 Audi with less that 100.000km)

in fact the fist and most important problem of diesel is (with my EU experience) that's not allowed to everyone. it's an amazing thing for trucks or guys who make long distance. and for sure all the technical system to make it clean doesn't help...

from our dealers here (VW) they saids that if you dont make at least 25.000 km/year and if you don't drive at least 30km ( without stoping engine) diesel is not a good choice ....

but i can definitely understand that torque and consumption can help people to choose this engine. and the 3.0 V6 diesel from jeep is a great engine for sure.
