What oil for Yanmar engine

I've a Yanmar 2GM20F. I uses EssoMobil Delvac MX 15W40 API CH-4, CF-4 ...-4, SJ/CF grade. My engine manual states only CD grade. Do I suppose the later/higher grade covers all older ones ? I checked on Torresen's web and they sells Yanmar brand oil (p/n: 41540) with the above API CH-4, CG-4, CF-4, CF/SJ grades for use with 2GM20F (I assume since it appears in the filter page for 2GM20F).
However, when I read my friend's 3YM30 manual, it states that the YM engine should NOT use oil with CH-4, CG-4,...-4 spec as this would cause excessive wear to the valve train assembly.
Now I'm uncertain if I should continue to use -4 spec oil for my 2GM20F for fear of same wearing on my engine. Any advise appreciated.

The 3ym engine meets the 2010 emissions, so reason for different oil and if you notice the injectors are on the other side another improvement for good burn, have a new yanmar in my morgan and real good on fuel.

Doesn't Rotella T cover most of the Cx Sx additives? Isn't this oil one of the best available?

I also use the Chevron Delo multi-grade in my 3GM. I was informed by the dealer not to use this oil in the trans. They sugested a straight 30 weight non detergent to reduce wear on the cone.

The 3gm uses a different oil then the 3ym, and yes the gear box takes a different oil then the engine, and depending on the slope of the engine, one has to be careful not to over fill gear box and cause foaming, which was something I learned the hard way but caused no damage.

These recurrent debates about lube oil seem to never end. This time I'll take the liberty of making the only important point to eventually result - that frequent changes of the oil and filter are FAR more important than what brand you choose as they are almost all essentially equivalent.
