Just drive one and you will know

Gunny, you do not even have your GC, yet.

There are a lot of good ideas in the previous responses. The one thing to consider is how you drive. If you are not consistently doing at least 20 mile trips, forget it. The diesel is NOT for 2-3 mile short trips. Although I have had second thoughts since ordering, as I found out more about the diesel, in the end I am sure I will be happy. Most of my second thoughts turned out to be for no reason. My situation, 30 minute drives with 20 on highway, going to keep JGC for long time, want the mileage, because I want it. It did spreadsheets to compare the costs of all three with pricing as I would order, at less than 75000 miles I will come out ahead.

It seems to work for my 2-3 mile trips just fine.

Re: Convince me as to why I want a diesel

I'm still trying to figure out all these "higher maintenance" naysayers....sure, an oil change is $90 or so. But...it's every 10k miles. My gassers get a LOF every 3k - at $30/each. Sounds like a wash to me.

Tuneup? It's called a fuel filter. No plugs. No wires. No cap/rotor/coils.

DEF? $17 to fill the tank at a Flying J pump, no harder than pumping fuel, and its not like you have to do it every week.

And diesel price? Do the math. Don't look at dollars per gallon - look at dollars per MILE. If you're comparing to a Hemi...as noted above, most Hemi owners don't run 87 octane. Do a real comparison.

Toss on top of all that, diesel longevity. LOOK at how the 3.0 is built - SIX BOLT MAINS. Girdle bottom end - not individual main caps, but a single girdle...and each main bearing STILL HAS SIX BOLTS. Rod caps are so beefy they had to put the seams at an angle because having them at a 90 to the rod...wouldn't let them fit in the cylinder bore. Just like the venerable Cummins. This is a serious motor. My Cummins has 225k on it...and I should probably do the first valve adjustment this summer. Sometime. If I get time. I did put a fuel filter on it at 220k. Other than that it's been...drive...fuel...tow heavy...repeat.

Diesels run cleaner now than gassers. Quieter. More torque. More real-world driveable - if you want to drag-race every stoplight, get an SRT gasser. If you want a durable, superior designed internal combustion engine (Europeans figured it out decades ago - diesel is light years ahead of gassers)...go drive a diesel with an open mind.

If you aren't willing to open your mind to something completely different (and a diesel IS a completely different animal, don't let anyone tell you otherwise)...get a gasser.

Just remember - a diesel is "different". Not "worse". And they're no longer stinky, smoky, noisy beasts. Try one. You might like it.

Most of your post makes a good case for the diesel. But today's gas engines can mostly go 10,000 between oil changes. You can choose to do them at 3,000, but that's just a choice.

Re: Convince me as to why I want a diesel

...still offset by the fuel-filter-versus-tuneup-cost ratio...but if folks want to debate, they can debate. I've owned gassers and I've owned diesels, and hands down the diesels cost less to own and operate overall.

The other factor is, they're less mechanically-stressed. MUCH lower EGT's compared to a gasser. Lower cylinder temps. More even temperature zones throughout the block/head assemblies. Lower overall operating temps - whens the last time you saw a gasser with a cold front grille blocker in winter, or heard a gasser owner bitching about "my engine won't warm up"? Diesels are, in the purest form, a more efficient engine and I'm thrilled that the US is finally starting to offer more oil burner options

I'm not debating which is better. But tune-ups on a gas engine, including the Hemi is not like the old days. Even the 16 plugs in the Hemi now only need to be changed every 100,000 miles.

I don't keep a car long enough to do anything but oil changes, so I'm glad we still have choices. And it is great that we are both happy with the choices we made.

Re: Convince me as to why I want a diesel

.....and develops max torque at only 2,000 rpm.
If you need to ask "why" you would want one, then get a hemi.

Re: Convince me as to why I want a diesel

You buy it for the torque delivery, not only for towing, but a full load of passengers and camping gear adds up, the diesel drives like there's nothing there.

That extra torque is very useful off road too. Here in Oz the diesels hold their resale value much better too, but that probably doesn't apply in the states.

As others have said, drive it and you will know. The hemi would be my 2nd pick.

Re: Convince me as to why I want a diesel

The EPA estimate is 8 MPG advantage to the ecodiesel for highway mileage. The number of hemi drivers who get anywhere close to the EPA estimate is very small since you need a very light foot on the accelerator. Even when I tried with my 2008 CRD, I couldn't drop the mileage below 20 MPG when I normally averaged around 21 or 22 depending on traffic. For comparison, the ecodiesel averages around 26 MPG on the same commute. I've started driving with the eco mode off and the mileage today was just over 27 MPG. The last V8 we had a was 2002 Grand Cherokee with the 5.9 liter and I was lucky to get 14 MPG.
