3.0TD Jackaroo Filters and oil.

Glenos,
while Ryco make very good filters the Standard Z79a when sat up beside the genuine Isuzu filter looks to be a lesser filter than the genuine. for a Deisel engine.the Z79a is a petrol car engine oil filter, deisel's require much better filtration due to the soot produced(yes the Direct injection does make much less soot than indirect injection) the advice has been to change the smaller filter every second oil change if doing 10,000klm between changes(using synthetic/semi synthetic oils)
as for the fuel filter, the ryco looks very close to the genuine in internal construction & cost wise the genuine was only a few extra $$$, would use either my last one fitted was a ryco.

As for the oil remember they don't like thick oil (high lower viscosity 20w-50w etc.) at start up they can have cold start problems as the oil pressure is used to fire the injection. if you are in a cold area or snow country they recommend 5w-40w or 5w-30(snow country). most normal areas 10w-40w or 10w-50w. for 10,000 klm oil change intervals synthetics get the nod over most normal mineral oils.

when it comes to servicing anything, always remember it's cheaper to change the filters & oil than the motor.

The best way to kill any diesel motor is to give it dirty air, fuel and engine oil.

the Diesel mechanics that are floating around on here might have something to say about after market air filters and how some bit's of them end up inside the turbines in the turbo chargers (foam types)

good luck & happy travelling

Old Jack is pretty spot on ,I worked at holden when they were trying to tell us that the secondary oil filter should never be changed until an engine rebuild. I argued long and strong that the secondary filter is for the injection oil circuit and as the two circuits are interlinked , both filters should always be changed. Eventually they agreed, but it just showed that Holden have always demonstrated a total lack of knowledge about the Jackaroos and still continue to do so.
Unfortunately Glenos, the Jack needs top shelf oil to ensure reliability and easy starting, you should change both filters and use at least 5w 40 , but dont be scared to use a 0w 30 either, check out Mobil Orbleeps. for their fully synthetic gear.
Just bear in mind that it takes 3-4 oil changes to fully flush the old oil out of the engine injection circuit.
As for air filters, the oiled foam element filters are fantastic and superior to paper sieve elements, as it is the sticky oil that catches the dirt, not the foam. The only trouble with foam filters is that people don't wash and oil them correctly , or believe that they will last forever. Holden even fit finer filter elements under warranty to turbo rodeos because the paper elements fitted in the factory are useless and allow an excessive amount of dust into the engines.
The Jacks are expensive to service, but they will repay you with years of reliable work. Brad

I've settled on Fina Filter for my TD jack - 18 months now - runs very well - not starved of air at all. I use Castrol Magnatec for the donk - change the oil at 5, with the main filter - change the small one each 10. The donk runs very well on Castrol Dynamax too - fully synthetic - bit dearer though, and only comes in 20's. For my climate, 10W-40 is the go (but she is touch and go on some cold mornings).
That's my formula. Gotta have red sand on those boots !

Just checked - mine is UNIFILTER not Finafilter.Gotta have red sand on those boots !
