What's better about Diesel?

So, I was about to dive in and get a 2013 GC, but now I've decided to hold off a while and go for a 2014.

Seems like a bunch of folks are looking forward to the diesel thing... Sorry if I sound like a total noob with this question (it's because I am) .. but what's so good about Diesel?

Better gas mileage? That's great, but around here for example, at the station down the street regular gas is going for $3.37, and diesel is $4.07. Is the added price per gallon just not gonna make it any better?

What else is is worth noting about diesel vs regular gas? If I were to get a 2014 GC, why would I want to pick diesel over regular?

Hmm you raise a good point. The biggest advantage thing that i see in it is better gas mileage, better power (Diesels make more power in the bottem end by nature.) And this is just me, but i like the way they sound

But with a higher cost out the door then gas and much more expensive to maintain(yes that is very true).The oil changes alone are double to almost triple what they cost for the gas engines,then you got fuel filters every year which ain't cheap.Parts and techs that actually have been trained on that engine will be very hard to come by also.

Check with your dealer on the diesel maintenance costs. They can give you numbers. And that's quite difference in fuel costs. More than I would expect.

Some places here still have diesel over $4 per gallon(or just slightly under $4) while gas is about $2.75 a gallon.Not going to save any $$$ that way.

You need to look at what your going to use your GC for, if your going to do a lot of miles or towing then the diesel is the way to go.
Also the diesel is quicker 0-60 miles than the Hemi, ( now before all you lot in the USA get all worked up have a look on the jeep Australia site for some real facts as we've had the diesel here for almost 2 years, so we can talk from experience )

Urea injection

Has to be filled and possible computer reset every 8K or so in the US. Question is is it DIY or dealer only.

I'm going to tell you from my experience owning a 05 Dodge 2500/cummins turbo deisel. First you get allot more torque than a gas engine of the same size. I normally get 21-22 mpg with my quad cab long bed truck, a comparable (power wise) gas engine would be the Chevy 8.2L which from what I hear gets about 9mpg and then goes down from there if towing. Deisel engines are also built to a longer overhaul scedule, for my engine its 300,000 miles. Deisel engines don't have hei ignitions, so you wont get "zapped" getting in or out of your vehicle and they can be fueled while running. Due to the diesel option my Dodge came with a 100,000 mile powertrain warranty. Yes I spend $50 on my oil changes every 6k, but that is 3 gallons of oil and a big filter. The fuel filter has to be replaced every 30,000 miles on my truck and it's $10, which I do myself. Lastly my truck holds 14 gallons of coolant and you'd have to do something stupid to overheat it.

My truck doesn't use urea so I can't speak to that.

Also before anybody mentions it, no diesels use glowplugs anymore they've all gone to intake heaters.

Might want to rethink that.The bigger ones don't but the little ones still do.Plus your 3/4 ton is designed for towing,the WKII is not with less then 1/3 the towing ability so not much of a need for 800lbs-ft of torque unless you were stupid and got the manual then your limited to 600lbs-ft.

ah .. ok .. guess I won't really need the diesel version then. It's going to be my daily driver, I don't expect to tow anything ever, and I don't plan to drive off road other than an occasional dirt or gravel road until the zombie apocalypse. I'll want 4WD for the 4 or 5 days a year when it snows. Really just want a super reliable suv that'll also be real comfy for yearly super long 10 hour road trips. I was looking at the Chrysler 300 at first for that reason alone, but I'm just a jeep guy at heart.

A AWD Charger or similar probally would be a better choice then and much cheaper.

Well I'm just more of a SUV guy, I prefer the extra height and extra cargo room when I need it. Every time I test drive a normal car I feel like I'm sitting in the street, can't get used to it after have SUVs and trucks for the last 20 years

It is not as simple. What everyone has said is true: better MPG and better driving dynamics at low speed/towing/rock crawling/city driving etc. But is it worth it ? I too have waited it out for the 2014s, especially the diesel. But it boils down to how much will the diesel be over the 3.6 L Pentastar V6 ? Will it be a 1000 ? 3000 ? 5000 ? 7000? dollar option. Quoting one of the worst dealers in Chicago, the diesel will be a 7000$ option. Which I do not believe. However...here's the calculations that made me think...currently the diesels are not ...all that worth it.

http://www.fueleconomy.gov/feg/savemoney.shtml

3.0 CRD 21 city 30 hwy (4x2 trim) - official figures. 240 hp; 420 lb-ft I will extend the same fuel economy to the 4x4 - maybe a stretch maybe not.

3.6 L V6 Pentastar 16 city / 23 hwy (4x4 trim) - official figures for the 2013 model. This may be revised upward with the new 8-speed as the values are for the 5 speed tranny. The new tranny is advertised as improving fuel economy 11% with the new ECO feature or ... roughly 18 city and 25 mpg highway. 290 hp ; 260 lb-ft of torque


OK...Chicago fuel prices. I will use Skokie, Illinois 60076 which is between home and work.

GAS BUDDY http://www.gasbuddy.com/

On Sunday 20 Jan 2013 at 21:00 hours the Lowest price is: Regular $ 3.47 - 3.55 (choice of 16 stations); Diesel Fuel $3.99 - 4.49 (choice of 2 stations). But since I feel it is not representative I also visited this link

GAS TEMPERATURE MAP
http://www.gasbuddy.com/gb_gastemperaturemap.aspx

and arbitrarily choose regular gas at 3.65/gal and diesel 4.10 /gal. Diesel prices around Chicago are a toss-up with large variations. It can be 3.79 by the airport and $4.29 due west on the same street, 3 miles away. So on with the comparison:

Quote:
Car 1 = the new 8-speed V6 Gas Jeep 18 city / 25 hwy;
Car 2 = the Diesel Jeep 21 city / 30 hwy;
SCENARIO 1
55% city ; 45% highway ; 15,000 miles/year; length of ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost $2658 gas / $2533 diesel
Car 2 saves me 876 dollars over 7 years.

SCENARIO 2
45% city; 55% hwy; 15,000 miles/year; ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost $2573 gas / 2445 diesel
Car 2 saves me $895 over 7 years

But wait...what if the fuel costs go up ?

SCENARIO 3
45% city; 55% hwy; 15,000 miles/year; ownership 7 years; gas $4.65/gal and diesel $5.10 per gal
Annual fuel cost gas 3278 and diesel 3042
Car 2 saves me $1655 over 7 years

But I intend to drive my Jeep only on vacations and more like 10,000 miles per year

SCENARIO 4
35% city; 65% hwy; 10,000 miles/year; ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost 1659 for gas and 1572 for diesel
Car 2 saves me 609$ over 7 years

SCENARIO 5
50% city; 50% hwy; 10,000 miles/year; ownership 7 years; gas $5.0/gal and diesel $5.0 per gal
Annual Cost Gas 2389 gas and 2024 diesel
Car 2 saves you 2555 dollars in 7 years.

SCENARIO 6
50% city; 50% hwy; 10,000 miles/year; ownership 7 years; gas $5.0/gal and diesel $4.50 per gal
Annual Cost Gas 2389 gas and 1821 diesel
Car 2 saves you 3972 dollars in 7 years.

Of course the diesel is the engine of choice to romp on Colorado trails. But unless the price of diesel fuel is significantly less to that of the gas it is harder to justify. The way I see it is that the diesel should not be more than a $2000-3000 dollar option as otherwise it is not a sounder investment. Unless you are a trail regular and you dip your toothbrush in diesel instead of Colgate...to appreciate the torque; the wallet is not going to thank you for saving 2-3000 dollars over 7 years on a $40,000+ I was thoroughly excited by the diesel; I still am...but it is not all that great for me in Chicago. Yes, if you do the math using a Volkswagen Passat data, with the TDI getting 31 / 43 mpg vs the gas getting 22/31 mpg the numbers do look a little better. What sucks though is the difference in pricing between diesel and gas. In Europe the difference is less. If premium and diesel were priced about the same, it would be a no-brainer. I also realize people would not be buying the Jeep diesel for the enhanced fuel economy. Buy it for the torque, buy it for off road, for the clatter; for every other argument but fuel economy and how it would save money. Cause it really won't unless you are driving that car a lot and you're keeping it for the next 3-4 presidential inaugurations.

PS:
Durango CO : 2.89 for regular and...3.70 for diesel.
Knoxville TN: 3.09 for regular; 3.79 for diesel
Boise ID: 2.97 for regular; 3.69 for diesel
For Myers FL: 3.39 for regular; 3.78 for diesel
