Diesel gives you low down torque,better fuel economy and engine longevity before repairs are needed.The drawback is repairs to diesel engines are expensive. Diesel has a pungent odour and the smell stays around. Diesel can be bought everywhere in Australia.

Petrol engines give you higer revs, plenty of grunt, are less fuel effient( although the modern computerised trucks are getting better), and are less expensive to repair. Petrol has a sharp odour which evaporates very quickly. There are some restrictions in obtaining ULP petrol in remote localities in central Australia.

The choice is yours.

Cheers from a petrol head,


Always going somewhere

hope you're ready to start ripping up $100 bills for fuel for a petrol patrol...

Yep.. I went down that road also and bought the petrol which i regretted once the honeymoon period had finished...
As Willem said the engines last longer with the diesel and are more expensive to repair "BUT" make sure you buy one with 200thousand or less k's with a good service history and you wont have to do much to it till the 500+thousand k's and if are smart you would have moved it on before then...
The things that crapped me off with my petrol RX GQ 4.2 was as follows......( fuel range on a standard tank was about 450kms, fuel economy is about 20litres per 100kms, it wasnt a nice feeling having a problem with water crossings, having to carry umpteen jerry cans just to make it through the simpson desert or cross to normanton from the development road-and almost not make that one, sometimes not being able to buy ulp at some communities etc etc,,)
Since then i have bought a GQ diesel 4.2 and i am saving around $300 each 5000kms i cover which includes the price of the oil and filter, i can fill up anywhere, i can travel 1000kms before i have to look for fuel again, can drive through water up to the bonnet with no dramas, getting 12.5litres per 100kms....
The difference is amazing...._____________________________________________

If you are rich disregard my answer and just fit a long range fuel tank and avoid GAS because it definately shortens the life of a petrol patrol.....

I have found and actual fuel bill here from my petrol patrol days and this was just from a normal day doing 100kmh on a highway....$76.50 to cover a mere 400kms...= 21.25litres per 100kms...

Another bill here from my diesel in similar conditions ... $81.00 to cover 720kms...=12.5litres per 100kms....

You will have people quoting all sorts of great figures from there petrol patrols because they must be in denial or something but if you buy one you will find out..._____________________________________________

As the other guys stated, the main difference between these models is that one burns petrol and the other burns diesel!

Hi Kro ,Ive got a 1994 rx petrol.Ive had a diesel patrol in NZ . I like both trucks.Voxson is right about the rx drinking alot of petrol.I currantiy get 450 around town and 600 on the open rd with a std tank.Regarding water ,yes you do have to watch how deep you go.But in saying that if you do drink a bit of h2o ,you dont have to replace the motor.Regarding Torque i find that i have plenty when i need it.Also when in mud and sand i find the extra power very handlie.1problem i find is it is great going up a hill but the engine braking isnt as good as my diesel ,But that comes down to Torque.If you are towing ,you find the petrol can get up hills a bit better than the diesel.If you would like to talk to me off the forum , my e-mail is terryupston@yahoo.com.au.As i dont want to get into petrol vs diesel discussion , because we will just around and around.Will done England Im still crying in my beer over the kiwi game

The only main benefit I can see for a diesel - is a bit more mileage from a tank of fuel.
I own a GQ LWB petrol, absolutely love both the performance and how quiet the engine is.
As to cost of fuel - it's the price per litre that we are ALL paying at the fuel pump that I object to.

Before deciding, firstly have a drive of both and secondly have a realistic think about what the majority of your trips will be - distance wise.
It's a matter of weighing up performance against fuel economy.

a "bit" more mileage from a tank of fuel?
how many k's are you getting from how many litres?
efi or carby? i am genuinely interested.......

Hi Voxon,

What was your petrol GQ – auto or manual?

Your quoted h/way consumption is what my LWB 4.2 litre carby manual GQ gets when travelling sand dune country (soft sand) and that’s whilst towing an offroad trailer!
H/way consumption is average of around 6.5 k’s per litre, again whilst towing an offroad trailer.

When I compare your h/way (diesel) figure (distance) to what I know I get from my petrol, then it’s only a difference of around 100 k’s per tank!

As for actual cost difference in fuel:
For example lets use a trip of 3000 k’s distance.
Current average price (All States) of fuel per Litre is 95.5 cents /L for Diesel and 95.3 cents/L for Petrol.
My GQ Petrol using 15.38 L/100 K’s (Based on my average of 6.5 k’s/L) = $440 total in fuel.
Your GQ Diesel using 12.5 L/100 K’s (based on your stated 12.5 k’s/L) = $358 total in fuel.

Unless I’ve made a mistake somewhere, the difference based on these figures is only $82.00!

For an extra 100 K per tank and a total saving of around only $82 per a 3000 K trip – Why would I even think about swapping for a diesel? – No Way!

Hi Robert.. Mine was a manual...And it was shocking... Must be an efi thing because i hear that sort of mileage a fair bit...
My diesel gets 12.5litres per 100 no matter whether i am in the country or doing a full tank of juice in the city stop start..

I am glad to see that there is a relatively economical 4.2 petrol out there..

Cant think of anything to put here just yet !

Hi Voxon,

Stop start city traffic is another matter, no way would I get anywhere near h/way figures, but we didn’t buy our Patrol for city use so that doesn’t concern us. Very surprised at your H/way figures (petrol Patrol), especially as efi in theory should be more fuel-efficient! Was yours duel fuel? Ours isn’t duel fuel; maybe that makes a big difference!

My 89 Maverick is the old school carby petrol. Gets about 17l per 100ks on the highway to 23l per 100ks around town. It is only a weekender, not a commuter so the fuel consumption doesn't worry me. I actually prefer it to my old MQ's 3.3 Turbo Diesel because it feels a lot less agricultural and still delivers the goods off road.

There are pros and cons to both . . . at the end of the day you won't make a wrong decision if you educate yourself and match your requirements to the vechicle.

What do you want to do with it???

Depending on that, they are both totally different.

Petrol = $$ on fuel (eh Luke :P)
Diesel = Not as much power, but more torque
