101 original lump vs a Diesel alternative

AS Ron says, put a 200litre drum in the back. When you want to do things like the CSR the rule is to top up the LPG at the last place it's available and run on petrol to the begining of the section where fuel endurance is required filling your petrol tanks at the last source of petrol.

For CSR run on petrol so that your vehicle tanks are on empty for unleaded petrol resupply at the Kunawarritji Community Store at well 33 and use the LPG only as a reserve before then. After well 33 the choice of which fuel to use is yours. The fuel dump at well 23 if it still happens, is not recommended as unsecured fuel was being stolen.

I agree with Diana - I have done couple of outback trips where there is no LPG. Fill all tanks and run on petrol and only run on LPG for the last 200km (gives a 100km reserve) back to where you can buy LPG. (make sure you still have petrol for this distance). This also provides extra security in case you have an issue with the petrol system and cannot repair it - likewise for the LPG.

Worked out you will need 5 200litre drums (they will fit and you will still be well under max weight) as well as 80-100l of gas and 110litre of petrol in the main tank to do the whole CSR with side trips and reserve. If fuel is guaranteed at well 33 then obviously less is needed.

You would rather carry a whole ton of petrol than add 200kgs of engine weight, I can see the logic.....

Garry, I think there is something wrong with yout sums. I thought the CSR was 1900Km and with your fuel calculations based on 5 X 44Gal drums you seem to be consuming 62.6L/100Km. Is that what you meant to suggest?

I'd have to mortgage the house to even contemplate the trip. :confused:

How does then fuel get to the Kunawarritji Community Store - in a bloody big truck with a big fuel tank. I think petrol stored in appropriate containers is relatively safe - really no different to the truck that used to do the fuel dump.

Hi Diana - nothing wrong with the sums - maybe my assumptions in working it out.

Assumed 2000km track - add a couple hundred for diversions to look at things on the way.

At Stockton I used up to 60l/100km but that was red line runups and climbing dunes - in hard offroad I may see 40 but normally about 35. So there is a safety margin to add.

I have never done the CSR and given that much of it is open country then I would expect fuel consumption to be less (maybe 30 on the open and 60 in the dunes but as I said I have not done the CSR so safer to carry more - remember we are not talking about a normal 4wd - the 101 has the space, and was designed to carry 1.5t cross country while towing 2 tonne. With the fuel load and other gear the 101 will still be well under its gross weight and that is to do the whole CSR. Most 4wds doing the CSR will be probably be overloaded at the start.

Of course with fuel available at the Kunawarritji Community Store then far less fuel would be carried.

Do you have gas in yours?
Do you do long bush runs - gun barrel etc or do you use it as a play thing rather than any kind of tourer ??

The 101 is my only full time registed vehicle at present.
I work for my self and my job requires me to be on standby to look after some hire forklifts I own,,,,,,,,,,,so long trips and holidays is out and has been for many years.
I also live on the lower east coast and the distances to get to places of attraction is not that far.
I would love to do the big trip around this place in the 101 and my 101 is able to do it, but you really need to question yourself and look at long distance comfort levels and aircon, power steer etc and and say is the 101 the best vehicle to do that sort of trip in the first place ?
Do a few 10 hour drives in the 101 and you will know where i am coming from.
I have petrol and LPG.
The LPG tank on my 101 is only small as it is mounted under the rear of the vehicle, but I am able to carry 3 extra fuel jerry cans without intruding into the cargo area.
My 101 is curently running the highest transfercase ratio advailible and overdrive with the 36 inch simex tyres.
it will cruise all day loaded at 100kph plus with the standard motor which is in good tune.
The limits is how fast you can turn the tailshafts with the standard 5.56 to 1 diff over time .
4.6 ratio diff are a options, but spreads the main gearbox ratios a bit and raises the low range crawl and a stock 3.5 is not happy with the 4.6 ratios.
The 101s become aero dynamically poor above 80 kph and the fuel burn rises.
I have a 4.6 in the works, but whisle the 3.5 is running sweet I can not justify the work and cost in the up grade.
Performance on road is equal to a TDI300 defender or a Isuzu county.
I really dont need any more in a vehicle never designed to be a high speed vehicle and the steering, suspension and brakes reflect this.
I find my 101 to be a compact tuff as nails high capacity little work horse and it shines as a off road tow wagon and is totally reliable.......just what the army designed it to do.

Hi Garry

Granted the 101 is a thirsty and heavy beast and would be more so with a tonne of petrol and your picnic lunch making up the remainder but 60L/100Km is significant consumption.

Some of the CSR is indeed heavy sand hill work but a lot of it is relatively smooth tracks.

If you review the exploroz site you find that the vehicle consumption is not that much greater than each vehicle's regular road use overall, but the issue is the total distance between drinks.

Canning Stock Route Trek Fuel Data @ ExplorOz

So with your on board fuel and using your own calculations of 40/100 you could likely dump 2 of the 5 drums, maybe more but as you say safety is important.

Diana

Fuel burn can be interesting on the 101.
Flat country at 100 kph or less it can be reasonable with the overdrive.
As Garry correctly pointed out everytime I take the 101 to stockton beach its fuel burn is very very poor.
Stocktons sand is very soft. and requires the little rover 8 to use its reserves of grunt specially with bar treads digging through the sand and not going over the top.
The local monkey gum track and it will use little as the low range work with or without payload requires running at 1500 to 2000 rpm where the little rover spreads its torque
How a amblance version goes with the heavier body and wind drag I dont know.

So called empty drums that have sat around for a decade are the extremely dangerous ones, full and recently emptied drums / fuel tanks, don't blow up.

The only disadvantage I can see is the all up weight over the tyre size.

Using a nicely tuned V8 with it's heavy use of petrol, against the cost of a change over to diesel on the CSR.
I would say it's debatable whether the cost of a change over against the petrol used, justify doing this work.
