Caltex Technical Paper

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.

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.
