Castrol SynTrans works very well in the R380

Peter the Castrol SynTrans is excellent in the 380 like garrycol said.
I believe that Nulon and Penrite have an equivelent oil.

Why ?? (and there usually isn't any difference in pumpability 'till you get under -5*/-10*C or lower in equivalent 10W-40 vs a 5W-40 oils)

If you really, really need a 10W-40, Penrite have 'Diesel SP' a low SAPS Euro IV HD diesel oil (do not use in petrol engines)
I've been using this for about 8 months in two engines. It's a bit cheaper than Delvac 1, but generally an order in option (20 litre drums) from a Penrite supplier. (they generally don't even know it exists) Zero oil consumption in the Tdi over 10,000km. It has a NOACK volatility of 9% or so, which is very good.

This is one of the reasons I wanted 10W/40, it has been using a bit of oil lately, my mechanic thinks it may help reduce the use of oil.

I couldn't find any around my area so I'm still using the Penrite 5W/40 again for this change.

I'm going to try the Syntrans 75W/90 for the gearbox and diffs.

Thanks everyone for the advice.

naa, not a bit, as the hot oil viscosity is the same and there is bugger all difference in viscosity at Sydney overnight temps.

If you can order the Diesel SP or Delvac 1 oil consumption should drop a little compared to HPR Diesel 5, which is a little more volatile. (around 4% more)
Every order so far of the D SP has been a special order from Bursons for me, and both times I've had to convince them that it actually exists (till they look in the system )

baz,
last time mine was in at bruce davis they have put penrite "manual gear oil 75" in the truck. seem to remember from my investigation this is equivelent to the old mtf product.
cheers
