I upgraded my oil from Delo 500 to Delo 400 and while I was there I picked up a technical paper on diesel engine soot. I am not pushing Caltex or any other oil but if you are able to pick one up it gives a good explaination of one of diesel engine oils biggest enemy. After sorting through the Caltex hype the explaination would apply to all oils.

Surprising you are such a smart person. Not a trait often displayed here. Normally the whaaackers want to buy stuff with names like Cruiser oil. I would not use Cruiser oil in my lawn mower let alone my vehicle.
You should be pushing Caltex Delo 400 as it is one incredible product and doing people a favour telling them about it. There is no other mineral oil for diesels that is as good as Delo 400

Caltex CXJ was excellent for me. found it better than 400 the cxj designed specifically for high revving turbo's. was more expensive though but what price do you put on your motor. Only danger was that for a lot of people it would be over servicing, like feeding strawberries to pigs. It's all about knowing your parameters and requirements

Amen Brother.

Your looking at a Biiiiiggggig fan of Delo 400 here.

Dont want to knock the little guys, but if Hiclone's, Cruiser oil's etc were *that* good, they would be standard issue in every new 4by.

I also think that Caltex publically publishing testing results of their oil's says pages in my books.

Hi meggs
What sort of steed do you have as no need to go from 500 to 400 if running older deisels. I run delo silver (500 has been changed to silver) in all my vehicles and is recomended for older diesels , I put it into my 2h deisel, hilux 2.4 deisel, 2f cruiser petrol, 2 falcons and a v8 commodore and works well in all. It is also resonably priced at $65 for 20 ltrs.
The cruiser travels the most ks at 1000 to 1200 a week and as I clock the miles fast I change filter and oil at 10,000 k intervals and it is not heavily comtaminated .
Best results I have ever had from engine oil.

Cheers Steve

Steve I have a 3l Hilux naturally aspirated dual cab. I will be doing some fairly heavy towing 1200kg and with Delo 500 the recommended oil change is 2500k I believe this is proberbly conservative. I am going up to a CI-4 oil and I am going to take the oil drain interval out by 25% mainly because it costs 25% more and then I will pay to get and oil analysis and see the results. If I can't reduce the oil changes there is no point in going to a more expensive oil. The degrading of diesel oils is primarily by soot. The technical paper gives a good explaination of the soot, how it is produced and what happens to it in the oil. I thought my hilux was a dirty engine but it seems as if the latest diesels are much worse due to the attempt to clean up the exhaust emissions. I don't care weather others use Cruisel oil, Caltex oil or Fish shop oil it is just the paper that is worth a read.
