What Oil Do You Use for Diesel Engines?

[Chaz]

Thanks Chaz, so are you using the SYNTHETIC 5 or the 0W50?
What change intervals do you recommend?
And did you have any oil usage issues like Ben-e-boy?

Is this it?

Thanks mate.

Paul,
I'm using the SIN in 0W50 and change it at 10K intervals, but I don't have operational EGR.
I've never had a problem with oil consumption, which may be partly because my provent empties back into the sump. i used Mobil1 in 5W50 for many yeas without any issues as well, but the Penrite has slightly better viscosity hot.
Check out THIS document.

Thanks Chaz.
Will give the SIN 0W50 a go next change.
At $75.00 for five lt, It still works out cheaper than the Nissan oil cause I will be changing oil every 10k instead of 5.
Thank's again for the info Chaz, much appreciated.

Paul,

The Penrite 0W50 is a good choice for a ZD30, but I wouldn’t use it in TB, TD or even RD motors. Penrite have changed their range slightly and THIS is the oil that I use. Most synthetic oil manufacturers suggest that you can triple your oil change intervals with fully synthetic oil, but personally I wouldn’t do that. 10K intervals work well for me and my oil starts to discolor if I leave it any longer. I also do all filters at the same time.

The Nissan oil specs are very hard to get, but I’d imagine they are very similar to Castrol Magnatec, so here is a comparison between the two of them and Delo400, another very popular oil for the ZD30.

Delo400 15W40
cSt at 40c 125
cSt at 100c 15.1
Viscosity Index 125

Magnatec 10W40
cSt at 40c 102
cSt at 100c 14.5
Viscosity Index 149

Penrite SIN 0W50
cSt at 40c 108
cSt at 100c 18.7
Viscosity Index 194

This shows that both the Magnatec and Penrite are quite thin when cold (40c), but the Penrite doesn’t thin out as much at operating temperature (100c). It also shows that the SAE rating means very little when it comes to the viscosity index. The fully synthetic oil clearly doesn’t break down as much at operating temps and flows much easier when cold.

Thanks Chaz.
I have printed off the data sheet for the 10 tenths premium 0, so now I will keep my eyes peeled for a good price.
Thanks mate

Hi all, I have been using Castrol GTX for years with no problems. Just remember when your out bush somewhere and you need oil. Any oil is good oil

I did a bit of research for My GQ and discovered that it requires a high ash ( calcium) oil and found that Shell Rimula R3x 15w 40 ( JASO DH-1 , CH-4) is suitable for my TD42 and is also available in 20L drums from Supercheap for only $89 ( May 2012). Apparently the JASO DH-1 is for earlier Japanese Diesel engines and only a few of the available oils satisfy these requirements. Delo 400 is another one that does. Hope this helps

To paraphrase all these posts, if I use any of the following in my GUIV '04 3.0 Di I will be fine.

Magnatec 15w40
Shell Rimula 15w40
Caltex Delo 400 multi grade.

I know where to get the Magnatec from but where would I source the Delo400. I live on the Gold Coast and while I'm prepared for a bit of a drive I don't want to go too far if I don't have to.

Thanks for all advice

My Nissan dealer recommends Castrol Magnatec Diesel 15w/40 I get the 10L drum for $78. Has been fine for me.
