Side by Side: CJ-4 vs. CI-4/CI-4 PLUS oil | Equipment World | Construction Equipment, News and Information | Heavy Construction Equipment

There are pros and cons to using the new CJ-4 oil. I would like to point out that to decrease emissions they decresed the zinc and phosphorous levels. Zn and P are the key/major lubricating substances in these oils.

"Conclusion
If you’re running 2006 or older trucks and off-road equipment there is no urgent need to migrate away from CI-4 or CI-4 PLUS oils. These are robust oils in their own right. But when you buy your first 2007 or later model on-highway truck, you’ll need to decide if you want to stick with the old oils and clean the DPF more frequently, or step up to CJ-4. (But again, there is no choice unless your 2007 engine manufacturer approves the use of the older oils.) Then you have to make a decision whether or not to stock and use two different types of oil or go with a one-oil solution and recoup the extra cost of CJ-4 with extended drain intervals or increased engine and component life."

 

Good article. Thanks.

 

Interesting read. But it is a 3 year old article, and at that time CJ-4 was new and you still had a lot of CI-4(+) on the shelves. I don't see much choice on the shelves any more. Most all the popular oils have been rated upward to CJ-4.

 

If you want to have some fun, CK-4 / PC-11 oils will be starting to hit the shelfs in 2011.

 

what the he!!
