Diesel is the best engine option.

[ilovebikes99]

When you get 25.5 Mpg around town and 30 on the highway, the slightly smaller tank in not an issue. How is your MPG? DEF cost $22 every 6000 miles and diesel is available at 95% of stations that I've been to. Here in Western New York, diesel is .05 cents more than regular and way less than premium- and did I mention 442 lb ft of torque???

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

The other 8 speed? Don't all the automatic wranglers/gladiators have the same 8 speed? The minivan has a 9 speed. The 3.6 engine is used in way more Rams, Wranglers, Chargers, Challengers, and Gladiators, Grand Cherokees, and Durangos than it is mini vans.

Nope. That's yet another diesel advantage. It gets the genuine and stronger ZF 8HP75. The Pentastar comes with the lighter duty and tweaked (ruined) in-house 850RE trans.

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.

The gasser is underpowered. I don't buy vehicles that are under powered. End of story.

I don't think anyone is upset. Everyone else is just expressing opinions too. It's often said, but tone can be hard to express online. This has been one of the least heated "debates" on here. I'd love a diesel. I just wasn't willing to pay for it or give up my manual transmission for it (and pay for that too haha). It is a great engine. But the gas engine isn't a bad engine, and minivan engine just is hard for me to wrap my head around when it's an engine more famous for being a Wrangler engine than a Pacifica or Journey engine. With all due respect to those cars, I don't think anyone who drives them (which is not many people; they aren't great sellers) even knows what engine they have.
That's all I'm saying.

Makes sense. Seems to be the same deal on the ram side: the v6 and smaller V8 get the weaker transmission. Being a manual guy, I didn't really research it that hard, but knew they were both zf based. Didn't realize the 3.0 got a German manufactured version. Thanks for the tip.

Well, the thread's title gives you a hint as to why. It's another garbage thread with some garbage responses.

Mute point, when was the last time there was an issue posted for either the gas or diesel transmission? Both pretty solid.

That's what I've always heard too, but after reading this JL owner's writeup of re-gens, as someone who primarily does short trips around town between big road trips every month or so, how it actually works won't be a problem for me.

Regens do not require highway driving. I was Internet-convinced that I would have to jump on an expressway and drive for 30 minutes in order to clean out the DPF. Nope, not at all. It turns out that when it kicks on, it takes about 10 minutes and I can just go the long way home to let it finish. It will continue to run through stop lights, and even while you’re in “P” or “R” for a couple of minutes. Though if you stay in either of those states for too long, it will stop and pick up again when it gets back to 80%. This could be only a few minutes (if you interrupt it near the threshold), or days if it has sufficiently burned clean. The process will also happen off-road, with the Jeep in 4WD (hi or low).

Short drives aren’t the most awful thing. But -- you need to drive long enough for it to get to temperature and sufficiently burn down once it starts. The Jeep takes about 10 minutes of driving to get to temperature and 10 minutes to regen. It seems there’s this bad spot you can get into where you “hover” around 80% DPF soot mass, but never drive enough to get to temperature and burn clean enough.

In regard to the opinion issue, as has been said before it may be to justify their own choice..Remember the saying? Opinions are like assholes, everyone’s got one.
And if you ever figure out what’s wrong with people, please share, but be sure to charge for the answer. You’ll make a fortune.?

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.

disagree. 2008 F450 6.4 in my old forestry truck. Original DpF,turbos and trans when it was sold in 2015 with over 350k. It towed most its life and idled in cold winter months in Alberta Canada winters. We had a 2012 6.7 that was equally as reliable. Zero issues in 3 years and 125k.

To each his own, opinions are like assholes, everyone has one. I won’t tell someone how to spend their money, however I will give my personal experience with what I have if asked.

with that said, personally I didn’t want the diesel. I’ve never turned a wrench on one. I’m familiar with gassers. Also I didn’t want to deal with the DEF, the extra weight and lack of options (at the time) for after market parts like suspensions.

granted even gassers have their own problems and draw backs, goes to the owner on what they want.

I wanted more power, so I also added a Magnuson supercharger to it and am very happy with the power out put. It suits my needs just fine. (Though not looking forward to belt changes or plug changes).

with all my mods I average 14 to 16 mpg depending on how aggressive I’m driving. That’s with the extra 400lbs weight I have added. No way shape or form did I buy this thing to be fuel efficient with trying to get every mile I can for every drop of gas, I got it to enjoy the off roading camping and hunting that I love.

with all that said, I have appreciated the different opinions on this site and have taken personal experiences with my own independent research to make the best choice for me. Thank you to all who contribute to this site and the flow of information. Jeepers rock

Why? I'm in cities and driving short trips daily. My oil analysis looks awesome and my fuel dilusion is below 0.5% at the end of a cycle. I've heard the constant "diesels aren't good for short drives" misinformation passed around a lot. Never have seen one person on any forum provide evidence as to why.

Now let's address some other misinformation in this thread.

As far as the argument about "tows less".. no it doesn't. Diesels have more payload in every trim except some Sport models. More payload directly translates into more towing capacity. It doesn't matter that a diesel is rated 6,500 and a gas is rated 7,000 GTW. The lower payload on the gas engine means that you'll run out of legal towing faster, which means the diesel tows MORE in the real world. And, the diesel will tow MUCH more effortlessly at a lower RPM which is less fatiguing for the driver, occupants, and the powertrain.

As far as the argument, "they're less reliable"... Open up Google and type in "Jeep 3.6 valvetrain failure" and watch your screen blow up. I'll leave it at that.

"18 gallon tank" OK... but you're getting a real world SIX more miles per gallon, so your range is still farther.

"Parts are expensive" Yeah but you've got 40,000 miles more factory warranty. Who keeps a Jeep past 100,000 miles anyway?

"Emissions" Yeah the EPA blows. But the Gen 3 engine has low pressure EGR that's used almost exclusively once the engine is up to operating temp, which means the air being forced back into the engine is much cleaner than on prior diesels. Use the correct oil and change before 10k like the manual says and you'll likely never see a problem with the emissions system.

"DEF fluid" OK so it's $7.50 for a 2.5 gallon jug at Walmart that'll last you 5,000 miles. If that is going to ruin your checking account you bought the wrong vehicle.

I agree diesel isn't going to save money. I've been saying that since the beginning. But 70% more torque and 30% more fuel economy is something that nobody should pass up when buying one of these Jeeps.

When I say short trips I don't mean a lot of them. I mean one day I may only put 5 miles on my Jeep. I put about 4-6k miles a year on my vehicle.

• I did not need the extra expense of a diesel
• Less choices of where to get diesel gas
• Gas sits in my tank longer I put stabilizer in at times
• Takes longer to get fixed because most dealers do not have a good diesel tech or as many
• Heavier engine.
• They need cool down time
• Just not for me and my needs.

Modern diesels are awful compared to the way they used to be. I've owned one and never again. Between all the extra stuff like the def and regen system.

Plus just how bad diesels fuel itself is now. Ultra low sulfur does not correctly lube the fuel system and you really need to run an additive to keep the injector o-rings in good shape. Also Ultra low sulfur, you go through a tank faster. I remember when we could get nearly 2 days out of a tank in our Skidder when logging. When they made all diesel ultra low sulfur, we were lucky to get 1 tank to a day.

Did they ever fix the 3.0 issue with the timing gears? Are they still just pressed on and not pinned/keys to the cam? If so, they will eventually slip. That was a pretty common issue with that engine. Saw a lot of them in shops needing new engines.
