Thanks to those who replied to my previous question about oil in my Jackaroo. I know there has been a bit of talk on it already, but I will now add another facet to the argument. You all seem to know what you are talking about, but so does my mechanic who says he specialises in oil knowledge!
He says that fully synthetics (say 10/30 or 5/30) would not be good for my Jackaroo (1999TD), because they do not produce the correct amount of ash that a diesel needs, and also would not give the engine enough upper protection during cooler weather. He does admit that I would get better economy, starting and power, but says the longevity of the engine would be compromised. Says stick with a 10/40 or 20/40, and recommended Penrite HPR10 which also will have the correct levels of dispersants and detergents for a Diesel. Also said Castrol Magnatec is no good for hi-tech turbo diesels, because of the above. Any thoughts appreciated because I am really getting confused now.

Thanks in anticipation

The lid is off the tin and the worms are moving now D. Castrol advised me that Magnatec is the best of their 3 or 4 oils that COULD be used in the Jack. Also, their Dynamax fully synthetic is a premium oil intended for fleet owners in the long haul diesels. Made for 20,000 intervals etc. My car was on Dynamax from delivery, then the dealer started using some cheaper stuff. Castrol said Dynamax was not necessary. I don't doubt your advisor was sincere, but the advice seems no more credible that the fload of advice on offer from all quarters - what to do ? Pic an oil from a reputable maker and run with it, while keeping all digits crossed and touching wood.I need red sand under me.

I'll second that last reply, the lid is off, I used Magnatec in my Rangie 250,000 plus K's and my wifes Sierra 120,000, both engines loved the stuff, don't know where the stuff was going but it wasn't going on the floor, with the Rangie it was difficult to tell.... I couldn't afford to use Magnatec, I've changed both to bp Coarse, they both haven't used a drop since, I run the GU on bp Vanellus C6, no problems there either, everyone has their own favourites, I was using Castrol turbo max in my GQ for a while that seemed to be OK. When I worked for Shell I used all their oils without much of an issue. These days a lot of these products are made to a standard, which are very tight, a lot tighter than the "olden days" so what ever "it" is "it" will either be consistently wrong or consistently right. Good luck, a few more worms will wriggle no doubt, won't be long before we're into the additives discussion again......................Keep the shiny side up

Buggered if I know, but mine's been on Castrol FMX Magnatec since delivery and that's what the stealer service dept recommends.

One thing I do know .... it's bloody expensive.

I guess at the end of the day you have to put your faith in someone's knowledge.

My Defender TD5 is running on Magnatec and it's recommended by the main stealer (to pinch a nice name for them!).
It's got only 14000 on the clock so far, so I can't comment on whether the stuff is good for it or not.
Have to rely sometimes on the advice from those in the know as they will be (hopefully) picking up the cost of engine damage.
If you've got a new vehicle I think it makes sense to use a premium grade oil in it from the word go.

For all the info you need, click here. You may want to print the pdf on this link and show it to your mechanic.

This link includes Holden's technical bulletin to the service industry on the 3.0TD engine's oil requirements and specifies suitable oils by name.

Your mechanic may know about oils, but his recommendation demonstrates he knows NOTHING about the Jackaroo 3.0TD.

I may have been a bit harsh about knowing nothing, but an oil that is 20W40 will give you problems.

Thanks for that SAVVAS. You are a legend. The bulliten basicalls sums up all the thoughts that have been going around this forum, and I was beginning to wish I had bought a different less-tech vehicle, but you have put my mind at rest. There are only 2 other questions that I had
- 1) is when to change the oil. There are no mentions of 3 months or 6 months with the 5000km or 10000km, does this mean the lubes will go the distance in kms and i don't have to worry about the time?
- 2) The bulliten says CD grages are general export grades and require changes at 5000kms, but I took it to read that any of the oils listed on the bulletin will only require 10000km changes? A simple question I know, but not so simple for the not so tech-minded of us.

Thanks again

The owner's manual says every 3 months / 5000kms.

However the tech bulletin supersedes that info, so I'd read it as every 6 months / 10000kms if you use CG4 or CH4 oils and 3 months / 5000kms if you use CD oils.

My personal preference is to do it every 3 months or 5000kms anyway. But that's just me.
