Gas engines can handle shorter trips as they get up to temp faster and run cleaner fuel. Diesels need temp and to run for longer periods of time more often to burn out particulate filter.

My wife drives ours often but she has a 20-25 min commute one way and we use it for long trips / travel and towing pretty frequently where our payoff of the diesel over the Hemi is much faster. Also don't run into need for forced regens at all.


I don't really agree with this. I live in Houston with stop and go traffic and the diesel has made a great difference. My mpg is much higher, like 50% more. I did get the GDE tune so turbo lag is a non-issue. The low end torque is money. I would never go back to gas unless it's my only option.

Eh, my EcoDiesel gets roughly the same in-town mileage for my daily, ~5 mile each way (no highway) commute as I got with the 15 year old V8 sedan it replaced. On the highway during the summer, the EcoDiesel gets about 7.8 L/100 km (~30 mpg) whereas the V8 sedan got about 9.5 L/100 km (~25 mpg). That's roughly a difference of 3/4 of a gallon of fuel burned every 100 miles of highway driving.

In the winter, my EcoDiesel highway fuel economy is more like the 9.5 L/100 km (~25 mpg) level on long trips. Worst tank average on the EcoDiesel was this February: 14.6 L/100 km (~16 mpg).

I don't tow, and my EcoDiesel is stock.

Exactly. Diesel FTW. I'm glad I didn't buy it to save money, though.

Did you also do any emissions delete? I did the GDE tune in my WK CRD when I lived in KS and didn't have emissions testing to worry about. That aside, from my reading of the failures posted here, most of the '14s early failures were from owners who primarily drove frequent short trips with lots of stop and go. Whereas those of us with '14 models who drove primarily longer trips with a lot more highway where the engine could get hot and clean its downstream emissions systems we were able to go much longer before the SCR failed. Mine didn't go until 26k miles thankfully after most dealers figured out how to fix them effectively. I think towing / hauling also made an effect as it works the engine much harder. I personally know one owner and read about other's who had the cylinder head failures where they were primarily driven in city traffic.

You won't see anywhere near 7.8 L/100 km (30 mpg) in the use case you describe, even with an aftermarket tune.


Nope. I always wanted a diesel and now I have one. Don't buy it expecting it to save money, though. You'll just be upset.
Wife has 23k miles on here 2014 overland eco-d. Gets 26mpg hand calc'd overall with over 30 on the highway. Since SCR was replaced no problems, and even before SCR replacement it was just a light, vehicle ran perfect. Personally I think daily driver is fine assuming there are some highway decent length trips thrown in here and there. Safer bet would be the Hemi I guess, but real world mpg would be much less than the diesel. Good problem to have for your wife though

My wife deserves that. It's her daily driver and she goes weeks between fill-ups. Plus, we use ours to tow our off-road trailer off-road.

You're comparing the ecodiesel Jeep 4x4 to a sedan. Might as well be a boat. The poster asking about if the diesel option is the way to go makes me think he wants a jeep and considering between diesel and gas. After 10,000miles I average 24.2mpg with a large chunk of it sitting in houston traffic with oversized tires on it. Absolutely no way the gas can get close to that.

Bought mine used and have put 10,100 miles on it. Zero issues. 80% of it is stop and go driving. Zero issues. Fill up at the cheapest stations, they usually have the most fresh fuels, and every few thousand miles I put a cleaner in the fuel.

Thing with diesels is that they run at lower temps and it doesn't hurt to lay the hammer down on them from time to time to help keep them clean.

A heavy V8 sedan that I regularly drove the same route that I now drive with the EcoDiesel and is highly similar to the driving scenario described by the OP, yes. It's absolutely a salient data point.

Furthermore, I have provided a substantial amount of hard, objective data I have collected regarding my EcoDiesel's fuel economy through a wide variety of scenarios.

I rented and drove a WK2 2013 V6 Limited for over 1000 miles the summer before I bought the EcoDiesel. It got about 9.8 L/100 km (~24 mpg) on the highway based on my manual tank calculations. Comparing that to the 7.8 L/100 km (~30 mpg) I get with my stock EcoDiesel Summit on the highway in the summer, that's about a 1 gallon/100 mile difference in highway fuel consumption.

Been running Banks IDash monitor on my 2015 Diesel, for regen active/off and cat temperature and exhaust temperature monitoring.
Have found during slow speed stop and go driving, DPF will go into regen active with Cat temperatures of 1200 plus degrees in slow speed driving. Active regen will go off between 5 to 10 minutes.
Have never seen DPF regen message on my factory dash screen after 9000 miles.
Unless you are at dead stop for long time, you should have no problems with Diesel DPF. Even at dead stop and DPF soot message comes up. You should be able raise exhaust pressure to blow out DPF by raising RPM'S at idle. Have found during regen 1200 plus Cat temps are made at low RPM.
You should have no problems with updated Jeep diesel emission system now days

Re: EcoDiesel for the Wife as a Daily Driver?

Maybe OP can clarify but my interpretation was he was deciding between gas and diesel GC also.

Re: EcoDiesel for the Wife as a Daily Driver?

If it is all city streets, then the V6 would almost certainly be the more economical option.

Mileage is still better than gas, but maybe not enough to offset the cost of purchasing the diesel engine.

The diesel JGC is too good for women; give here the 3.6l.
