So, just what is what? It has both ci and cj, not to mention ch, cg, cf and cf/sm. What does all that mean?
If it has CJ or "low emissions" on the bottle, it is the new emissions friendly diesel oil, which means it has the reduced additive package. Diesel oils typically had boosted Zinc levels, but they also have a high detergent package that in essence tries to clean off the anti-wear coating. I would consider a CJ oil to be borderline. I'm not using them.
For passenger car rated oils, avoid anything with SM or SN rating UNLESS it specifically calls out protection like the silver bottle of VR-1 does.
My silver/grey bottle of full synthetic Valvoline doesn't say anything special about 'protection'.
It says on the label;
exceeds API SERVICES SL/SJ, CF/CD, ILSAC GF-3
