I am travelling across the Simpson Desert - East to West in June (WAA line) expected kilometres 658.
I will be travelling in a Strandard 6 cyl 100 Series Diesal Landcruiser. HZJ105R.
I will be well loaded...carrying five people and all the gear including approx 125 litres of water.
I have two tanks with total capacity 145 litres.
I wondered if anyone had any advice on expected fuel consumption...whether I need to carry extra fuel etc.
Cheers Greg

Hi Greg,

The desert has had rain and is pretty benign. Current usage is about 100-110 litres for your type of vehicle with 150 litres recommended that you carry.

Thanks Ian
Companions (2) will be in a 3.5 petrol Pajero. Any ideas re how much fuel needed for 650 klm, Rig Rd crossing? They expect to take 135 l. Is that enough do you think?

Hi Greg,

I would consider that undercooked for the journey to have a that margin.
Normally we advise unleaded to carry 200litres. At this time the desert is fairly benign.

yep I would allow 25l/100km for the petrol and about the same for the diesel, so thats around 150 for both

I hope you're not really "Strandard" and yoou meant to say standard :) In the 3.0l Patrol I planned to take 185 litres (125 in the tanks and 3 jerries on the roof that I would empty into the tanks as soon as I could) and I was sure that was too much, but better than not enough

Hi Greg, We crossed the Simpson in 2003 but from west to east. Averaged 13.5lt per 100km from Mt. Dare to Birdsville. Only 2 people and usual overload of gear. Just taking things pretty easy travelling at a steady pace. Same vehicle by the way.

Greg on almost every crossing from Birdsville to Oodnadatta I've used between 105L to 110L in a 1Hz Cruiser. Although that will leave you 35L spare I have always carried one additional jerry in case I needed to take the 60 km Eyre creek detour or if there was local rain making it heavy going around Spring creek, the clay pans & salt lakes.

I think you are overloaded and just asking for trouble. A good load for those conditions is 2 people to a car. You will be digging divots on each sandhill and shovelling sand to get unbogged. Don't expect too much sympathy from the people travelling behind you when they find you are bogged, blocking the track. But if you still try it then good luck. I think you will need it.

Come on Ian - that's coming on a bit strong.

Yes, 5 people and 125l of water is probably likely to end up with an overloaded 100 series technically, but if it is taken easily it is not really going to be a drama - there are plenty of 100 series out there doing just that.

In reality they might get bogged a couple of times, but rarely is this going to happen when someone else is wanting to get through, and if they don't have some patience, they really shouldn't be out in the desert anyway. At least they have 5 people digging potentially, so they may be bogged for a lot less time than some 2 person vehicles.

Yes, it was strong but my guess is, that with that sort of loading and the driver asking about fuel usage that he is inexperienced and the car will be in standard trim probably with Dunlop Grandtrek and no H/D suspension.
If carrying only 2 people the the tyres can be lower pressure and the thing won't get bogged to have to dig at all.
But ask yourself this question. Would you do it?? I bloody wouldn't and I don't think you would either.
I really do hope they have a successful trip but they are stacking the odds against themselves.

Well that's a fair few assumptions Ian.

They are travelling with another vehicle.

If they aren't barnstorming across the desert, they can run tyres that bag to the same extent as a vehicle with 2 people in it - hopefully not Grandtreks - if it's a Standard though, it probably has split rims - I don't think they have Grandtreks do they?

They're going West to East as I recall, and without too much effort you could bog a vehicle on the soft tops with two people on board ... I've seen it, as I'm sure you have. If they are a little prepared, they should be able to extricate themselves, and someone will certainly help them within the space of a few hours, I would say.

Compared to some of the vehicles that cross the Simpson they have quite a bit right - they could tag along with me with just a few stipulations.

Andrew who wonders what Ian would say to Len Beadell and his follies.

Andrew, you didn't answer the question. Would you do it?
If not, why not?
Len Beadel was a little more savvy in the bush than all of us combined I suspect.
Don't get me wrong though Andrew I just think they are pushing their luck. My 80 series would have been struggling to do it before I fitted the turbo. I couldn't get over Big Red prior to turbo fitting but now... no worries with two on board.
Let's hope all goes well for them and I am just a little over cautious.

Well I said I'd be happy to have them tag along, but yes, I'd do it. I have a normally aspirated 1HZ and take it loaded over Big Red with 5 pax - sure, I don't have Grandtreks and have lots more clearance, and for sure - experience is an important thing, but I'd do it with stipulations - recovery gear and recovery points, shovel or two, not too much gear ... hope that helps.

i agree i crossed west to east in a 2.8 gq 2A,3kids well set rig still heavey load 110l mt dare to birdsville and climbed big red no probs air presure is the way slow and steady wins the race. i know this is the easier crossing ,but common sense and preping and reading the conditions is paramount .

Hi Greg
I crossed from east to west early may in my std 100s (1HZ) 2 people 60 liters water, 100 liters SPARE fuel, 2 spares on rims, total gvm 3340kg (approx 250 kg over weight) used 106 liters from Birdsville to Mt dare via WAA, lone gum, Rig road.speedo indicated 660 km
The Troopy I was travelling with used 110 L (1HZ with extractors/exhaust, but preaty much std).
Having done the crossing comfortably on the two std tanks I wouldn't cross there unless I had at least another 20l spare cos things change out there and you really don't wan't lingering doubt and worry about having enougth fuel.
previous replys made mention of damage to dunes due to excessive weight in vehicles,which is a contribiting factor,but the biggest cause of damage, is tyre pressure left too high, my 235/85 16s (yep,splits) worked well running at 18psi and never gave a hint of axle tramp.
excellent journey,buy a fly net ,

ENJOY ,Shane

Hi Greg, I did the crossing Aug Last year on my own (same track - opp direction) in the same vehicle as you. Because your revs will (should) rarely exceed 2500rpm then consumption is not really any higher than normal road use despite the slow going. Use the torque of the motor and not revs. Average speed for the desert was about 9km/hr and I reckon average rpm was about 1400. I used about 115L (which surprised me), mind you I would have been lighter than you will be. I carried a 20L jerry just for good measure and poured it in the tank as soon as I had room. Ran 18PSI cold (235/85/16) for the whole trip except for Big Red ofcourse and never had a drama - slow and steady over the dunes.

I think I was lucky, because conditions can change quickly out there, but the trip was a lot easier than I expected. In the 2 days I was on the WAA I only passed one other vehicle but could hear people throughout the day on UHF, most likely on the French Line.

Enjoy, Enjoy, Enjoy!!! And a plug for Ian and the crew at Mt Dare - definately stay there on the way out and enjoy a good beer and feed and good ol' yarn.....followed by a well deserved sleepin ;))

Hi Everyone,
Thank you for all your advice. We have been out into the desert before but in a troopy in 2001. I have just changed over to the Standard Series...hopefully not strandard as posted. I have BFG Goodrich All Terrains on the Vehicle and have upgraded the suspension. We will be doing a big weigh in and spread out of gear this week end to hopefully keep things as manageable as possible. We orginally had two in the vehicle but the other bods vehicle fell through so perhaps somewhat unwisely we said come with us...Hopefully it will be o.k.
Thanks again for all your helpful responses....including the cautionary ones.
Cheers Julie

Gidday everyone, like Julie said, thanks for all your replies.

Julie and 4 others are in the 100 series.
There is me and my wife in a 3.5 (petrol) Pajero.
I figure I need 135 l so am taking:

lpg tank - useable 68 litres which equals about 52 of petrol;
aux petrol tank of 48 litres, around 44 useable litres; and
70 litres of petrol in cans
for a total useable 156 litres.

Ian at Mt Dare that they advise unleaded vehicles to carry 200 litres. Any ideas for a Pajero or I guess the Prado would be similar?

Also, I've been told that by running in 2 wd in easy sections will save fuel; is there any truth in that?

Greg (2 in the Pajero; not the 5 in the Cruiser! thank heavens)
