What Oil Do You Use for Diesel Engines?

[mudski]

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)

Yeah i run Castrol Magnatec Diesel in my td. I ran it in the zd so i thought i might keep on with the same oil. Although im temped to use Rx Super, its CI-4 plus rated, next time to see. As i can get this under $100 for 20ltrs...

I saw that rx stuff the other day actually and nearly bought some but decided to stick with gtx. Whats the difference?

I've used the RX super in my GQ previously, a mate recommended it to me. They use it in Trucks and heavy machinery he reckons

Technical difference not sure. But there is two rx supers now. RX Diesel and RX Super plus, i think they are called.
Both CI-4 but the plus is CI-4 plus rated. From memory, RX Diesel is the old Rx Super formula and the Plus is Castrols new formula. So i think i will see how the plus goes next few services. You need to do a few services before you make your mind up as the motor needs to adjust to the new oil. But i did noticed with the magnatec it was quieter during the morning start up...
I worked in the transport industry from 1992 to 2011 and all we sold was Castrol, aswell as OEM oils. The name has changed a billion times over the years. But RX super we sold crap loads of this stuff. Its been around for yonks. Yeah there is plenty of other oils to chose from, you can even go synthetic if you wish, but at a quite marginal cost difference.
I suppose if i sold a different brand i would be biased for that brand...
I know and have used Castrol in every vehicle I've had so i stick with what I know i suppose.

Anyone know who stocks 20l of Delo 400 in Sydney?

I have just read this thread from start to finish and I think that I can say that I am better informed although overwhelmed...
The DELO 400 seems to be an oil of choice, if you are going for a mineral oil and any number of the current synthetics also get an honourable mention.
I have always used less 'processed' oil (like gulf western or valvoline) but included an additive like Moreys oil or Flashlube (the oil additives).
I have always had good results with these (add it to any oil based product like auto trans/power steering fluid, engine, diff or box oils) but have not (yet) used it in a Turbo'd computer controlled oiler. (Let me add that I highly recommend these additives)
Has anyone else used these products, and if so, what experiences have you had?

I tried the delo 400 in my old ZD30. I ran it for 3 services. I found my engine breathed heavier ( catch can had more oil in it) and the motor was noisy on morning start ups. So I went back to the Castrol Magnatec Diesel.

i found colo heights servo has 20 L drums of delo for just under $100 i pick up a drum when the wife gets her wine....

I'm running Castrol Magnatec Diesel now and thought of giving the Delo 400 a run... But if it aint broke don't fix it!

I have been a big fan of Penrite oils for a long time now, ever since someone convinced me to try it in my old HX Holden, made it quieter & stopped oil consumption completely.
I used HPR Diesel 15 (15-50) in my GU2 which was still running sweet when I sold it with 270000km on it.
The new Patrol has only had dealer service, the sticker 7 the invoice says they used Shell Helix, no other info. so I will use that for the 25000km change then back to the dealer for 30000 service.
My testament to Penrite is that I used the original HPR Diesel in my Hilux from 100000km to 320000km when I sold it and it did not consume oil & ran sweet. Like the HX the guy that bought it said it was the best one he had seen, gave me great bargaining power.
