With my second vehicle, I rack up around 20,000 km annually and use around 2,500 litres of fuel.

I wish I could do less.

24.1L/100km average? I think you need to take the hand brake off. Worst case I was thinking was around 17L/100km average.

12.5L/100km for your other car is the same as my Focus XR5.

Yeah, unfortunately. I can never bring the fuel consumption on the HEMI below 23L/100km. It's always between 23 and 27. This is mainly city driving (peak times). I can't see how 17L/100km is possible.

If I do mixed city & freeway in between peaks, I'll get around 19L/100km, but the peaks quickly kill the average

Mate, I've never seen anywhere near 27/100, even when towing in the city!

I used an entire tank of 91 over the weekend, typical urban with 2/3 people aboard, and I took the opportuntity to be mild (not soft) on the throttle, and I averaged 15.8/100.

As I've said before I can easily average 22/23, but that's over a tank of trips less than 5klm in distance, when it's always running rich on cold start.

*** Worth mentioning that when I run my standard wheel/tyre package, saving about 20kg per corner, economy improved by around 2l/100 over my typical grind.

I'm guessing the same size or bigger will fit in the 2011 model and will ring Parnell to find out.

I have a 4.7l V8 on LPG injection with the tank in the spare wheel well. It uses about 2l more per 100 km on LPG than petrol. On the highway the computer changes from 11 to 13 when doing about 110km/h on the same flat section when I switch between Fuel & LPG.

Frustration is that when driving around town, I run out of gas after about 230-250kms and it fits 55l ($35). Cost is great but more than anything else, having to fill up so regularly is a pain in the bum.

I can't believe this, tell me how you do it I can only dream of that fuel economy.

I can't even get that when I travel long highway trips to other towns.

First service 6000km, 2nd 12000km, 3rd 24000km etc

2/ how much does each servicing cost for the HEMI?
Each servicing will vary but on average will be $350 to $500

3/ if I were to covert the HEMI to LPG what factory warranty implications would this pose?
Please see attached file.

4/ what is the service interval for the diesel?
First service is 5000km 2nd 10 000km, 3rd 20 000km etc
**
5/ how much does each servicing cost for the diesel
Will be similar to your current Grand Cherokee from what the mechanics tell me.
**
6/ any update on when you might have an overland in stock
Overland looks like it will be here late may.
**
7/ finally, any news on diesel pricing
Nothing official but will probably be the same or very similar pricing as the Hemi...."

Now I have to sit down and work out if the cost of running the vehicle after the lpg conversion is the same as the diesel considering the less servicing required over the 5 years I plan to have it for.

Decisions decisions

Don't believe a sales me on the costs of servicing. The following is straight from a service manager at a Jeep Dealership. Nothing under $400 and up almost $1400 for major service. Much more expensive compared to other manufacturers which is putting me off, but I love the car!!

Diesel

The service intervals are 10,000km or 6 months

10,000/6months $463
20,000/12months $567
30,000/18months $463
40,000/24months $1360
50,000/30months $1062
60,000/36months $607
70,000/42months $463
80.000/48months $1360

Petrol

The service intervals are 12,000km or 6 months

12,000/6month $455
24,000/12month $493
36,000/18month $1077
48,000/24month $1255
60,000/30month $455
72,000/36month $1115
84,000/42month $455
96,000/48month $1255

What lpg system are you using? Because Parnell have said that there VSI system doesn't change power or economy what's so ever, also Parnell have told me that in the next few months they will be releasing a new lpg system that will provide more power and better economy than using petrol, this will also be covered under factory warranty for 3 years then has an extended period for another two years. Also, since I will be novated leasing the vehicle the government grants for lpg conversion are not excepted - bugger
