What Oil Do You Use for Diesel Engines?

[Rexzilla]

Been using Penrite for a long time in all my other cars with no issues, when it came to the patrol the choice was easy.

Been using Penrite for everything for as long as I can remember. Just had a dealer service and I supplied the oil. Engine is smoother and quieter.

Decided on the Penrite HPR 5 semi syn 5-40w for the ZD30, hopefully it works out and looking forward to trying it, also means Penrite throughout the Patrol on all oils now.

Can you make 10,000km with 15W40 on a TD42?

Hi all,

Does anyone know where i cant get Caltex delo 400 oil in Sydney, i cant seem to find anywhere.

I found a place the sells Mobil Delvac MX 15/40 and they say thats it is as good as delo 400.

Im after 20ltrs

Cheers

Phil.

Anything that is ci-4 rated will be fine mate. Both the mobil and delo are the same spec.

Ok so I have an 09 ZD30 crd. After reading this thread I think I should be ok to use Castrol GTX diesel 15W40. Got onto a20L drum for about $70. Conforms to API CH-4/SJ. Also says suitable for turbo engines and not suitable for particulate filters.
Anyone got any reasons I shouldn't? Only a couple of guys on this thread use it.

Cheers
Simon.

Have used Penrite in the past. Found it smoked a bit more than I wanted. Now using Rimula X and no probs but will probably try Delo after I finish this drum. Seems to get a good wrap from a lot of people.

By the way, how do people base their opinions on the quality of the oils they're using?? Do they have their used oil analysed in a lab or is it just gut feeling? I don't know how you can tell unless it gets analysed.

None of the oils I have used in the past have affected engine sound, power, fuel economy, etc. (4.2 TD)

I had the same issue with penrite, I'm running castrol GTX now and she seem to like that much better. about $120 for a 20L a supercheap bought one two days ago. Interesting bit of knowledge too, is I have a mate who works in a workshop (mostly trucks) and they do lab tests all the time, most castrol oils always come back clean and surprisingly so does gulf western (I refuse to use this stuff though had a bad run out of it in my other 4by)
