an auto diesel on the beach would be better though.
and its always petrols that are burning out clutches in the sand, not the diesels ;)

agreed, you cant go past a turbo diesel mated to a good auto box on the sand

im having similar thoughts when i upgrade my GU...
TD42T or TB48 :?

diesel = more frequent oil changes and oil costs more
less power on hills etc...
can drive further without having to fill up as often
diesel costs more to buy (initial purchase price and fuel)


petrol = cheaper to buy
plenty of power
uses more when towing
petrol is cheaper to buy
oil changes less often and oil is cheaper to buy



and more differences...

for what i will do with the car i cant see a clear winner, both have good points and bad points

The GU 4.8 is a power house, and a petrol hog,

used one as a support car for the Oxfam run a while ago, got to drive it, and man, the trip from Mosman to Brooklyn (Hawkesbury River) for the checkpoints ate fuel like it was going out of fashion, but the amount of power a TB48ES puts out, its scary, it matches the 5L Commy V8.

They both have their pro's and cons,
if i was only doing light off roading i would stick with the petrol / gas
if it is more rugged 4wheelin and extended trips off road i would say diesel

you can get your diesel injected with gas giving good results from what i hear , one point in favour of the petrol if the fuel pump craps itself its a hell of a lot cheaper than a diesel one

just my 2c worth anyway

I dislike the way power is delivered in diesals, especaially on softish ground where you need instant wheelspeed that a petrol motor provides .. drop it back a gear and mash the throttle.

The off idle torque in technical terrain is great, but gears in the T/case on a petrol will solve that issue.
On road with a turbo diesals are OK as I know I a driving a 4x4 not a go-cart.

The water thing is a non issue as far as I am concerned. it is not hard to make a petrol motor watertight, a bit of silicone grease properly applied does amaziing things for sealing water out. A diesal motor ingests water while it is running .. usually due to the very high compression it is rooted .. a petrol unless you have been pulling huge revs .. pump the water out .. dry the plugs and away you go .

Sand and overheating ... I have had much bigger issuse keeping hard worked turbo diesals cool that hard worked petrol motors .. either way there are plenty of ways around this.


If you spent big $$ on the diesal outback challange style .. obviously alot of this changes .. for the average weekend warrior the petrol\gas would get my vote.

finding a good patrol that has been WELL MAINTAINED is going to be ur biggest issue. i know either of the motors are hard to kill, but it's probably a better idea that'll save u money finding a mint body and driveline, regardless of whats under the bonnet. both will do what u want, trust me. a lot of nice city driven tb42's for sale lately, for a lot cheaper than the diesels. if u look for a type of car specifically, u'll often find urself paying more because of impulse.

For the people who have compared ther economy betweeen the petrol and the diesels, what results have you gotten with what engines?

I spoke to someone driving a GQ on gas/petrol with 35's and he was getting 200kms out of a 110L tank of gas! It put me right off EVER getting a petrol/gas fourby....

I've just used a quarter of a tank to travel 225 klms in my LWB GQ TD42 DIESEL. Not bad if u ask me. No idea on the petrol/gas tho...

also makes a BIG difference if you dont correct your diff ratios for larger tires.

OK I can get 750km from my TD42 diesel if I want (standard 90Lish tank). I could probably do more but not overly keen on getting stuck without fuel... :lol:

But its slow. Almost painfully. And with the 33" tyres is no better in the rough stuff than a TB42E (EFI) in regards to low down torque. Both require a bit of clutch slipping. No where near as bad as say a 3.0L or 2.8L diesel though.

If I could do it again - GQ i'd go dual fuel. Piss off the TB42 when it cracks its head (which it eventually will with my driving..terrible history with cars, so far I've worn out every car I've had hehe) and put a V8 in there. They're cheap enough to do this nowdays - you can get a GQ petrol in really good nick $4000 cheaper than you can buy a diesel in average condition.
