Hi there,

I've recently bought a 2006 5.7 Limited. A fairly rare thing in the UK, according to the register there are only 157 on the road compared to over 1000 3.0CRD versions. A colleague has a CRD Grand Cherokee which set me wanting one.

Its done 100k, only 1 family owner and has an LPG conversion, the cost of fuel over here and the crazy annual road tax for big petrol engines is a killer but given the way things are going, this could well be my last chance to run a V8.

Jeep dealers and parts are seriously expensive in the UK. I've tried to get a replacement spare key and they want $500+20% tax.

I've just ordered a big load of service parts from the USA from Morris 4x4 center. There were cheaper alternatives but Morris seem to sell genuine Mopar parts and i'd rather go with that if possible.

It runs fantastic and must be one of the most comfortable cars i've ever driven and the performance is so effortless. I really love it.

So once the kit arrives, my plan is:

Oil and filter
Air filter
Transfer case oil
Gearbox oil and filters
Front and rear axle oil and LSD additive
Power steering oil
LPG filters
Spark plugs

If I decide to keep it longer term, i'll get the wheels refurbished and look at changing the water pump (coolant has been changed recently) and maybe even the timing chain.

Hiya buddy, welcome. I'm from the UK also and was looking for a hemi with LPG when I bought my CRD. I looked for a while but the hemi is indeed rare, which is why I bought the diesel. You Jeep looks great pal.

Will.

Welcome from another UK owner. Also on a CRD. Was it actually cheaper to get parts + ship + import tax? If so, I might have a more serious look at US online shops.

Greetings and welcome. I was looking for a V8 when I bought my CRD last August. I got one with only 37k miles on a 2007 and was fairly chuffed with that until just after that there was a 2007 V8 with 31k and fulll service history etc....:smiley35:

However, I love my CRD (second one I've had). As one of our American cousins pointed out it actually has more torque than the V8, and I do tow a twin axle caravan.

So far I have been tidying up some bits and pieces, had the wheels refurbished and some paint scuffs done. In the process of fixing the leaking sunroof and next is an Apple play radio, reversing camera and some extra lights front and rear. Nothing too radical, although I am tempted by a Superchip tune.....

Lots of good folks and excellent advice on here. :smile2:

Hey, I'm thinking about chiptuning also. I have CRD with stock power and seems to be lazy for me now. My plan looks: 275HP and 620Nm. This is maximally variant which I can see on offer. Tomorrow my Jeep will get add heating and next day new OME lift. Then I plan new tires. Still wondering how big they will be. I have to wait on lift and than I can see how rooms will be there for new bigger tires.

i am so jealous of you UK guys with the CRD. Id take one of those in a heartbeat. Unfortunately the CRD is very rare in the US...

A tune and bigger tires and CRD's get 25+ mpg... they come with 3.73 final drive stock which is actually too much gear for ideal highway mpg on stock tires.

I was hoping this to be true also mate. I have a CRD and at the moment with 29" wheels I'm sitting at 2500rpm at 70mph. Thats not great for a diesel where max torque begins at 1600rpm. Like you say, I'm planning to fit the biggest wheels possible with a decent lift to bring those motorway RPM's down to a more reasonable 2000rpm or as near as possible.

Currently I average about 23mpg on the 29 inch wheels and UK gallons are bigger than US! Shocking for a diesel.

Cheers, Will.

THey would be so much better with the 3.7L 3.07 final drive in stock form. But they take to bigger tires nicely so thats a bonus.

For those with the LPG conversion how big is the tank and how many miles do you get between fillups?

For those looking for better CRD mileage you could run 3.07 front and rear... those gears are available for the front diff which is the tough one to find parts for.... or if it's RWD only let your imagination fly........

I'd not noticed anybody had replied to this!

Anyway, thanks for the welcome. I've had the Jeep about 5 weeks now.

The LPG conversion has a 90L tank. I think you can only fill about 80% though. The conversion on this one uses Prinz kit which is supposed to be one of the best. It is completely seamless in operation, very impressed. I'm not overly impressed with the fuel consumption though. The trip meter shows 15mpg but the reality is probably around 10mpg for runs less than 10 miles. I'll be doing a 400 mile round trip journey in it next week so can report back.

So far i've found Jeep parts prices in the UK to be absolutely crazy hence using USA suppliers, in all honesty though, after the taxes I probably saved very little. I'm a bit of a stickler for genuine parts but i've researched enough now to be looking at alternatives next time that are more locally available. For example I think i'll try Wix transmission filters. The only thing I can't find an alternative for is the transfer case fluid, Mopar NV245/247/249 seems to be the only fluid meeting the spec. Any ideas? Even the 'special' power steering fluid can be found in Febi Bilstein 06161 (MS-10838) for a fraction of the Mopar price.

I've just had a spare key made by the local locksmith. I got the key from Banggood (China) for £18 posted to my door and he charged me £40 to code that and another of the genuine keys I had that no longer worked so I now have 3 fully working keys! Jeep wanted £367+vat (20%). Ouch.....

A friend of mine has an 06 Grand Cherokee CRD, when he bought his, i was hooked on wanting one (the CRD is really good) but I really wanted a petrol. In his words, the V8 is a 'different beast' performance wise but his is completely standard. In many respects I should have bought a Cherokee instead but I really fell for the Commander.

I've now done all the maintenance discussed in my first post. Most things were as straightforward as can be expected but the plugs were a real pain, needing multiple sized extensions and a tiny little torque wrench.

I've read a few articles on replacing the coil packs. LPG needs a strong spark so this could have some real benefit to me, I can't post links yet but if you google HotRod Hemi Coil Pack Upgrade it has actual dyno data for the change. They tried Sultans of Spark coils but MSD make something similar I believe.

Next will be some replacement bottom arms though. Have been an MOT advisory for the last couple of years with that infamous yellow crayon marks all over them!

I've just done 374 miles in it purely on LPG. So the figures are in:

First tank: 135 miles on 36.5 litres (52.9 uk pence per/litre). The first 20 miles were local shorter runs, the rest was one steady run. So 16.5mpg :D (4.5 litres to our gallon)

Second tank: 239 miles (tank fully empty a mile before the gas station) on 79.35 litres (61.9p/l) so 13.4mpg. The first ~140miles of this tank was local running around the lanes of north Wales, the latter ~100miles on a run (generally with fast accels from roundabouts and over the mountains of mid Wales).

The first tank was done at 44% of the petrol cost equivalent at the same station and the second tank 49%. If you discount the first mile on petrol then it really is viable to run the V8 for around the cost of a diesel if not, a little cheaper.

Of all the things I love about the commander, its fuel economy is not one of them haha! Luckily, we just bought the wife a CRV so the XK is simply mine to drive, which only happens on the weekends.

Whats the LPG/GPL situation like in Spain now? I regularly go to Spain so i'll like take the Hemi next time.
You can find LPG in Repsol gas stations, which are common, and there are other brands serving it.

You can access this map to see all of them

Hi just seen your post, welcome!!

I’m another LPG Hemi owner in the UK and like you have really started to get under her and changed all the oils and wheel bearings, added a K&N intake system, magnaflow 18” muffler, next is an OME HD kit with 3/8 spacer up front, bigger tires and probably some floodlights using a cool bracket from a guy called Jesus who I found on the commander page on Facebook. They look very cool.

I’ve got a king LPG system and had to change out all the plugs, new coils clean the throttle body but now driving like a dream! Likewise getting about 16mpg on the display

I saw someone mentioned tuning and wondered if anyone has had any luck finding a tuning box over here as Superchips flashpaq doesn’t work on our XHs annoyingly!
Cheers
