1) Consumption (petrol not diesel): We used our Montero 3.8 L. Because this engine is not sold now in Australia, and because few people seem to use this model (equivalent to a Pajero) in Australia, we found it tough to get insight into the probable
fuel consumption. Experience in deserts elsewhere in the world led us to conclude that we would need to plan on 25-50% higher consumption than on tarmac. We saw advice online ranging from 50-100% higher consumption. At Mount Dare the advice was to plan on 50% higher than "normal" and to plan on the possibility of taking the longest route (770 Km), since the shortest route was badly chopped up when we were crossing.
So, we calculated needing around 195 L of petrol. The
tank holds 88 L, and we had cans for another 100 L, so we bought one more and left Mount Dare with 208 L. We ended up finding that the French Line wasn't as bad as we had expected, and ended up on the French Line,
Rig Road, WAA line, Knoll's Track, French Line, and then QAA line. 610 Km in all. We filled from cans once and when we arrived in
Birdsville found that we had used 135 L, so a lot less than we thought we might need.
2) Where to carry
fuel cans? We carried the reserve cans on the roof rack, if they’re positioned
well you can then drain directly to the main
tank, which avoids having to lift them down. We had no problems in the Simpson, HOWEVER, in East Africa we had one can spring a leak through fatigue. This was travelling with our LC80 and was diesel, which is messy when it leaks. The cans were
well-secured and protected with carpet, so this didn't help. Most of the “roads” were not bad although the main tracks in the Serengeti are atrocious (the leak occurred earlier in the trip, and we had seen relatively few bad corrugations to this point). I agree that you should drain the reserve cans as early as you can. On the Australia trip we had reservice cans which were empty until the first point we needed extra
fuel (GRR) and once we had completed all of the bits of the trip on which extra
fuel was needed we gave them away to the fire service in NSW.
