G'day Julka,
I have a 98 3.0TD Jack, and it is a great truck. The previous posts are correct it like expensive oil. I bought mine in July and did an oil and filter change pretty much as soon as I got it
home. Unfortunatlry the sales rep for penzoil was in the
shop and he "conned" me into trying a new brand of oil called conoco it was 10W-40 pretty thin but not thin enough. I live in
Hobart, so it gets cold here, not freezing, winter temps in the single figures.
The truck has been blowclods of smoke on startup and running a bit rough, vibrations through the seats, gear stick. On Friday I changed the oil again this time I used Mobil Delvac 1 5W-40 synthetic. I made the choice based on conversations with Mobil lube line, castrol lube line and 3 Holden service managers (2 here and one in Melb who used to service my vehicle.
The Melb guy said, use Delvac 5W-30, this is no longer a std product and is about $320 for 20L, Mobil lube line said 5W-40 is the rght choice $200/20L, castrol said Formula R Synthetic 5W-30 $55/5L.
Hobart mechs said, Castrol Softec (same as Formual R) and Delvac 1.
When I quizzed the melb mech about Castrol Magnetec he said, "No, don't use that s**t, use Delvac 1 5w-30, there is 5W-40 but the 5W-30 is better."
This is not a cheap solution, but the Jack no runs smoother, no
seat vibration, starts easier and almost no smoke on startup. I plan to change the oil again in a couple of weeks to fully flush out the other crap. Next time I will do the filters as
well.
If you didn't know there are 2 oil circuits that are interlinked and it takes three oil changes to fully exchange the oil.
do a serch here for Jackaroo and you will learn a lot.

Hey Glenos, seeing as you are in tassy, you can also go with a 0 weight oil such as Mobil 0w30 or F.u.c.h.s 0w20 . Don't put too much faith in holden for this problem as they are the ones who put twin batteries in so that you could crank the motor for minutes and overwork the starter and still not get it to fire. I personally argued with holden that the secondary filter on the injection circuit should also be changed, when i was working there as they said only change it at engine re-build time !!
Anyway i won and convinced them that they should be changed every time, but most dealers will do it every 2nd main filter change. The dealers will also tend to throw whatever crud oil they have in the bulk tanks in to them - usually 15w40 or such. The injectors are electro-hydraulic, they are triggered by the computer to fire, but rely on oil pressure to actually inject, so the thicker the oil the harder it is to flow through the tiny orifice in the circuits. With this motor , the better the oil (fully synthetic preferred) and the thinner the grade , the better they will go all round. And you are correct, it does take 3 oil changes or so to fully flush out the old oil. if you have any other questions let me know and i will see if i know , or have any relevant tech lines at
home. BradMoo... everyone knows what a Jackaroo looks like :-)
