Hmmm. That may be depending upon which spec. Do you recall which spec? I'm fairly certain that Mobil Delvac 1300 Super 10w-30 has moly in it (I believe it was a VOA here) yet it does show Cummins CES 20081.
No I don't remember. It was also years ago that I saw it. My body guy buys a new Cummins every 2 years. I was talking to him about MOS2 so he emailed Cummins. They apparently allow Molly fortified oils now but at one point they were concerned but the market has proven that Moly adds are harmless so they no longer warn against it.
Sunk ships post is old news.
There's nothing wrong with Moly that is included in most modern engine oils add packs, although most of them don't contain very much. It's the original old spec high Moly and Moly snake oils that caused the trouble. I think Redline are about the only real high Moly oil I've seen recently.
The Cummins problem was a classic example of what happens when you don't use an oil approved of by the manufacturer and ignore the warning in the handbook that says don't use oil additives.
