My neighbour owns a specialised Mercedes mechanical repair shop, and chose the GC as its the same engine/box as the ML Merc, at around half the price, at least here in Oz it is anyway.
He's also chipped his, and it really punches now. Has substantially more torque at lower rpm than my 5.7 Hemi.
Yes, I can see why your neighbour would want to buy it over the Benz....the diesel version was very popular in Canada and outsold all other engine choices in my area....that Mercedes engine is really terrific--even with the turbo lag....

Currently, diesel is selling for less than regular gas in my parts so it is even a better deal as far as fuel economy right now...

This was when gas prices were at their peak. being only 20 or so HP lower then the HEMI and having FlexFuel capability i went w/ the 4.7.

I'm kind of wishing i went HEMI now for a few reasons:
1- very few stations offer E85 right now
2- i wish i had that 20 or so more HP
3- and a Laredo w/ a HEMI is rare

I'm hoping a few years down the line E85 is more abundant - that'll make me feel a little better.

But i tell ya what - your little write up about the diesel at least makes me feel better about not going w/ that..
Hi,

Keep in mind I was discussing the only few disappointments with the diesel.....so I hope I didn't turn you off diesel forever...

Despite the drawbacks listed above, I feel it is actually the best engine that the GC has had.....basically you have the Hemi power, with more torque with better fuel efficiency and better resale value......don't forget, in general, the diesel engine will last longer than a gas engine....and the Mercedes diesel was also very quiet and cleaner running than the gas counterpart (especially the 3.0L bluetec version now available on the ML class Benz....

I do hope you actually test drive a diesel version in the future (if available) and see for yourself....

Yes, I think the Hemi would have been a better choice in the alternative for you for the reasons you give....I think it would be worth a little more in resale (altlhough obviously you have to pay more for it initially) and it is newer technology as well, along with the benefits of MDS....

The E85 doesn't mean anything in Canada as there are no stations with that fuel in my area anyway....

Interestingly, I asked my dealer when I bought my 2010 which engine I should get....He told me to get the Hemi over the older V6 since he thought it would keep its value better....

I didn't want to take the chance and void the warranty so I continued to go to the dealership for service....it was the old 'better safe than sorry' thing...

Either that or find a dealer with one in stock and make a dealer trade with your local dealer if possible...

As far as the right gas stations to go to in Canada, I've tested several and Esso has by far the best fuel quality with Shell being the worst. I filled up twice at each one I tested. I Tried Esso, Cheveron, Husky, Shell, and Petro Canada. Those are the most common stations that serve Diesel in BC.
Esso: avg.14L/100km
Shell: avg.35L/100km.
Cheveron and Husky: avg.17L/100km
Petro Canada: avg.23L/100km
I tested all this before the engine was even closed to being broke in.
I'm getting 9L/100Km now with 17,000km on the engine and still using Esso.

These results probably won't help you American guys but I'd suggest testing a few different Stations.
Yes, I believe you are correct regarding the warranty....I believe that is what he warned me about....and I did not purchase a warranty given that I don't keep my vehicles probably long enough to pay for them....good for you for looking into that part of it though...

P.S. Wow....I definitely did not test different stations.....I wonder how reliable that would be as as far as generalizing beyond your local area though?? In my local area, the only stations that had ultra low sulphur fuel (during the time I owned the vehicle) was Shell and Petro Canada....so didn't have much of a choice...

What could be the reason that you guy over there need to go see the dealer every 10k????

Diesel fuel over here is also cheaper than regular petrol, you pay more roadtax for a diesel (something to do with extra tax for "dirty"vehicles).
But with the better milage you get with a diesel it's a different choice over here..........
Yes, that is great that diesel fuel is cheaper... explains why Europe has mainly diesels on the road.....in our local area, diesel prices tend to fluctuate, some months it can be much less than regular gas and some months, it can be more....

That is an interesting point to make when looking at benefits/costs...

If most diesels in europe have an interval of at least 20000km or more, and Mercedes even let's the car decide when you have to go to the dealer for service (around +/-25k). They also use for petrol cars sometimes an even greater interval.


Why should a mercedes diesel in a jeep car need more service than the same engine in a mercedes car?


Owned previous diesels as wel (VW/Lancia/Alfa) and they all had an interval of 20000km or more, whilst the interval of my petrol cars where around 15000km.
Only on my Ducati bike do I need to chance the oil every 10k, and believe me that is a vehicle needing more attention to service then my jeep
I was just following the service manual.....regarding required changes....not sure about Europe diesels (haven't even been there on vacation!!)....

Mine was special ordered. I live in NY but bought from the Detroit dealer that American Expedition Vehicles works with.

I needed a 50 state legal vehicle as far as emissions goes so the dealer had to go back to the factory. At that point i basically had any choice of option combination i wanted.

I pretty much got all options i could afford - it is running QDII which has performed FANTASTIC off road.

And 1 of the coolest things (at least to me cuz i'm easily amused) is the sticker has my name on it

yea - i just have never been a diesel guy - i always have been a big American V8 kind of guy. but 1 thing about my truck is i plan on driving from NY to moab sometime in the next few years and it make me nervous to only have a 250 mile range on unleaded gas then even less on E85.

That's the 1 thing that would me look at a diesel - the extended range.

Re: Some thoughts on owning an 08 Jeep GC diesel...

I bought a service contract that covered all of the scheduled maintenance for 50,000 mile which is expiring so I've been looking into oil change options. I took our old rig to Valvoline Instant Oil Change and was always happy with their service. I found some specs on their oil but don't see anything that specifically says "low ash."

Re: Some thoughts on owning an 08 Jeep GC diesel...

I have a question for anyone with a diesel WK or whatever. How many MPG/KPG are you getting or how many miles/kelometers per tank of fuel do you get?
