Charlie.I think any good brand of oil will do the
job.I,ve lived in that country some years ago and
did a lot of off road work as part of my job.We
used Toyota landcruiser and Hilux 4x4s and never
had any breakdowns caused by bad lubrication.I
think your ps f350 will be fine for the trip but it
is advisable to have an extra vehicle with you in
case of problems.Its a long way to help and people
die in these areas reguarly.Expect temperatures in
the range of 40 to 55c.I,m actually taking my F350
up through those areas in a few days but i,ll be
taking the bituman road this time!You can get all
the oils you want in Perth which you will probably
leave from.I,d be glad to answer any queries on
local conditions.

-Arctic gear lube (viscosity of ATF at 100C.=7.1
-cSt, AGL=14.6), 0W-30 synthetic arctic motor oil
-"Sub-Zero Fluid" 10.5cSt. Any ideas about these
-products or others? I'm planning on using 85W-140
-in the diffs (31cSt) and maybe straight 40 in the
-engine (70K miles). Right now I have to carry 4
-different fluids as spares: hydraulic oil for the
-winches (of course for hydraulics in a pinch
-anything will do), ATF, gear oil and motor oil.
