What Oil Do You Use for Diesel Engines?

[TheFlyingBadger]

I use the genune nissan oil as the 4bee has only done 50,000km (4yrs old). At what k's do you change?

every 5000Km

[snicko]

every 5000Km

Sorry I mean how many on the clock

Sorry I mean how many on the clock

oh, yeah - so you did! I've only done 11000Km, and i'm on my second lot of delo (changed myself at 5K and supplied oil for 10K service)

Thought you guys like to know of my recent experience with Caltex.
My GU 3.0 is currently running Magnatex with no problems, but as there have been somany recommendations
for Delo 400 I decided to go to the Caltex Depot myself and check it out. The price was right
$95.00 for 20 litres, but I asked the obvious question of the agent. Is it right for my vehicle?
After some checking on the computer data base and a call to head office the consensus
was that it is not suitable as it conforms to CG4, which I believe the Zinc content can damage
the catalytic converter, and there appeared to be some doubt as to the lubricating demands
of the ZD30. The end result was that they recommended Havoline semi-syn, which is a
Caltex product as well So I left confused. I went to Autobarn next and they more or less
said anything that conforms to CF4 is o/k to use including GTX3, I sincerely doubt I would
ever concider putting that in my ZD30.
So as it happens Repco had a sale on Magnatec, 10 litres for $62.95. That will have to do until I can get
more clarification.
These engines are far too finicky and costlt to take too many risks with, particularly oils. I change oil & filter every 5k's
and feel as confident as I can with Magnatec.

Hi Phil,

While I personally haven’t used Delo400, I have done some research on it and I think the info you have is wrong. The Caltex site say’s that Delo400 Multigrade is API CI-4 PLUS, CI-4, CH-4, SL, SH, ACEA E7 or JASO DH-1. It also say’s “Also for Euro 4 compliant vehicles, except those units fitted with diesel particulate filters and requiring ACEA E6 oils” which makes it ideal for the ZD30.

Having said that, I think Castrol Magnatec in 10W40 is an excellent choice and possibly the better choice in a colder climate. The Magnatec has a 40c cSt of 102, which makes it a bit thinner than the Delo’s 125 cSt at 40c for cold start viscosity. At operating temperature, they are too close to call, the Magnatec has a cSt of 14.5 at 100c and the Delo thins down to a cSt of 15.1, so not much in it.

To sum it up, if you were to choose between the two, I’d use the Magnatec in a cooler climate and the Delo if it was hotter weather, but they should both be suitable for the ZD30 Patrol. Personally, I use Mobil1 in 5W50, but will soon be changing over to Penrite SIN 0W50.

good reply.
The Castrol Delo 400 Multi (not any other Delo) is certainly recommended for the CRD ZD30.
I think if you meet the specs. from Nissan you wont go wrong and I also suspect that the later model 'non grenade' ZDs are a more reliable motor and will do a longer run between services.
We maybe shouldn't get too passionate about what make oil if they all meet the specs. and I'm thinking somewhere between the good old 5K. for oil and filter changes and the new numbers may well work.
Will we ever know?

I'm using Magnatec 10W40 in my 2004 ZD30. I notice a lot of you use Delo 400 which i beleive is 15W40. I'm in Kalgoorlie where the weather is pretty warm most of the year round.What grade do you guys suggest to use for the warmer climate.

Cheers

Gary,

I wouldn’t be too concerned with the manufacturers “W” rating because there is no real standard for it. In some cases you will find a 15W oil to be thinner than a 10W oil between different manufacturers. Check the cSt ratings on the oils spec sheets to get an accurate idea on a particular oils viscosity because there is a standard between manufacturers in this case where they must quote cSt levels at 40 and 100 degrees Celsius (cold start and operating temps). Delo 400 Multigrade would be ideal in your case, particularly if you do a lot of highway driving.

[scrubrat]

Thanks for the info Chaz. Next oil change I might give Delo 400 Multigrade a go. It seems to be a popular choice among the ZD30 owners,so it must be good.

Cheers
