Is CJ-4 interchangeable with CH-4? Is CJ-4 better?

C stands for compression engine or diesel engines..the next letter is categorized or rated better in alphabetical order, hence J is better than H

Better rating is the proper replacement should the older or lesser grade (recommended by the manual) is no longer available or hard to find already

Thanks again Egan

Have you any observation as to the benefits of CJ-4 vs CH-4?

Gas yung vehicles ko, bro. In my case, I don't experiment much on using different categories as I just follow the manual.

the newer standards are better
