Hi guys

Am looking at Holden Jackaroo's and i cannot decide between the petrol or diesel model. I have heard that the diesle 3.0 was very good but too advanced for its time, which meant it became unreliable. however i dont know if that is know a problem seeing as there are a lot of diesel holdens around.

I like the 3.5V6 but im unsure on the fuel economy. ive heard its around 15 litres per 100 km which isnt too bad for a 4x4.

But yeah, i am really just wondering which would be better. i would be using it off road in WA, mainly on sand, maybe a mundaring trip in the future...

Thanks Guys

Stay away from the Diesel. Major problems and expensive to repair.
Petrol Jack is ok

Cheers

Depends on which model. The diesel with Unit Injection (actually developed by Caterpillar) did give problems when owners did not follow the exact oil requirements. These used oil pressure to operate the injectors and the wrong grade caused issues. If you have a hunt around for a specialised Jackeroo forum you might get a better answer. Try outerlimits4x4.com and look in the GMH/Isuzu section.

The 3.0L diesel (from Oct. 98 and on) is the one to avoid in my view - do yourself a favour and go petrol. A search here and elsewhere will get you plenty of info to mull over if you need it - the grade of oil in use was a biggy, but that was not the end of the saga - only the start.

I've owned two 3.5 V6 petrol Jack. Underated 4WD in my opinion (I still miss the comfy seats). I suffered a few problems after water crossings on Cape York but I guess the same could happen with any vehicle in the same conditions. I could only achieve 15 lit/100 unloaded on a highway trip. Around town it was more like 18. A very reliable engine. I'd imagine you could pick one up very cheaply. Cheers.

I have a 3.5 petrol auto that has 245 000k's on it.
I drive like I care about the vehicle, no high revving, no boy-racing from the lights etc.
Around town, without a load on the vehicle, and sticking to the speed limits, I get around 15 l/100k.
On the highways, again at the speed limit, it drops to 13l/100k.
Towing a CT, horse float etc, and maxxing at 90k's and slower on hills, I still get around 15l/100k.
I had the restrictors in the exhaust removed and a semi sports muffler fitted, and fitted a snorkel, combined improving the fuel usage by 1 to 2 l/100k.
My usage is checked from a Scangauge, not guesswork.
Loaded up and travelling at 100 to 110 kph, I run around 17 to 19l/100km. The extra speed is a killer in more ways than one.
Over 3 years, and 70 000km, maintenance has been servicing, a rear diff oil seal, and tyres. Nothing major or exciting.
Good comfortable drive.
Can't help on the diesel.
Cheers
Ian

Hi James

Do yourself a big favour dont buy one (diesel ) i worked for holden when the things were first sold nothing but troubles with them.
the twin battery where put in so the cat injection system would work the engine had to spin over at something like 700 rpm on the starter motor before it would even start so if your batterys where a little weak in charge your walking to the campsite
the petrol might use a bit more fuel but its a ok motor trouble is there all getting a bit old like most of us

hope this helps

G'day James, I have driven three Jackaroos..the first petrol SE & a good vehicle. The two 3 litre diesels in SE form were great until they just shuddered to a stop for no apparant reason. What a nightmare of a vehicle thank goodness they belonged to the "Firm" & not me. My advice. Don't buy a Jack get a Pajero 3.2 Diesel auto.....great machine & will do everything you want.

Hi James. I have put a link to the Australian 4WD Forum below. You will find a very substantial section on Jackaroos and on the 3.0 litre TD diesel.
The 3.0LTD has a lot of happy owners. I am one of them.

Hi james,
I had an earlier 3.2 lt petrol and then 2002 3.5lt petrol. Both really reliable the first reached 340k before I traded it on the 2002 model.

I think you would have to drive like you were in a funeral procession to get 15lt/100k.

I am and have been, a member of the Holden 4wd club of WA for several years and I think you would find the general consensus would be similar reliable but thirsty.

I would not go for a diesel in a jackaroo

Another biased 3.5 L Jack owner am I...I have put 70k on mine without even the most
minor issue. 90% of that was touring..towing an offroad C/t. 2000 model auto gives
15L/100 towing regularly...if kept around 90 kph...run it up over 100 kph & expect to
pay bigtime. Does 13L/100 not towing at 100 kph. That may be funeral march stuff
to some, as Noldi suggests, but it suits our travelling style just fine. There is no better
value petrol proper 4WD wagon on the market. Plenty of sub 200k jobs around for
around $10k. Look for the best cared for ones with good service history. Paid $14k
for mine 5 years ago with 80k on it, now has 150k & i wouldnt take $20k for it. It has
taken us to the Gulf, Kimberley, Bungles, GRR, Tanami etc etc & been faultless. I
wasnt game to take on a diesel after researching them & dont regret it one bit.
Dont buy the first one..check a few out & be sure to establish title is right.
cheers......oldbaz.

Thanks for all the replies

i am a fan of the 3.5L

but my mate reckons the 3.0 as its from the Isuzu Trooper and they are good. but the price of the petrol and for the amount of kilometres, its outstanding compared to other 4bies. ive been on a 4wd trip with a 3.0 diesel. performed very well. but according to my dad, the owner had the bonnet up nearly constantly back at home...


but i dont mind those fuel econ figures. quite good actually considering my 2.0l RAV4 does 11L p100 depending on terrain and whos drving.

you can pick up a 3.5 with around 150-180km on them from 7-15 grand depending on model and quality.

VERY GOOD, its also a Holden!!! :)

If $$ allows - forget the Holden all together - IMO the ONLY 4x4 to look at is either Landcruiser or Patrol - the rest are just wanna be 4x4's ( yes i know bold statement )

My brother in law has the Holden jackaroo(petrol) - he tries to do the same 4x4 driving we do - he has endless repair bills - i am yet to spend 1$ on repairs from 4x4 trips ...

im limited to $10000 unfortunately and have no interest in buying one of those considering fuel bills and the amount of k's. i dont want to buy a car thats done over 200,000kms no matter what brand.

Thanks anyway though. i do like the 95 landcruisers though and the next model...

James - the car i mentioned only had 80k on it when purchased, paid about $27 000 for it - i paid 23k for my 4.2 tdi with 200 k on it ----

he has probably spent close to 10 k in repairs in that time - me - only shocks and the usual oil filters /oil tires

i now have close to 400 k - blows no smoke - tows a 2.5 tonne boat - starts first time every time.


BUT as i said in my initial reply - if you want a good reliable that's not going to cost the earth if its actually used as a 4x4 and not a glorified taxi - then its Landcruser or Patrol

My 98 3.5l 5-speed manual with alloy BB driven 'normally' (not flogged but not 'carefully') almost never returns worse than 14//100km and is usually 12.5-13. I'm talking around town and on highway of course, not offroad or towing. 2 or three passengers and a small load make little difference. Been a very good vehicle.
