This is on a Case 821 front end loader with a Cummins 8.3L engine. It has about a 20 quart oil capacity so I used three cans of MoS2. We used to use Texaco Ursa that had a descent amount of Moly. We switched to an oil that didn't have any and the iron count went from single digits to 20 which is about the same now. That might be coming from the high fuel content which about doubled since the last oil change. Even though the unit does see a lot of idling, the last time the fuel was this high it was due to a leaky fuel pump. I'm going to replace the fuel lift pump in hopes to bring the fuel level back down. The unit has 9740 total hours with 322 hours on this oil change.

Use Chevron Delo 400 or Ursa LE and you dont need Lubro-Moly. BTW not much Moly in Lubro-Moly.

I think the Lubro Moly he used as actually the MoS2 additive, which is all moly.

I'd keep an eye on the fuel if it's "double" the last UOA. Clearly, you already have a plan of attack; that's good.

Rest looks really good.

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...

Regardless of the higher-trending iron (which is really not all that high taken on it's own), and the high fuel (not related to the oil), this is a great report for a 9700 hour engine.

167 ppm of moly is a good amount, not too much and not too little.

I think the MoS2 particles might not be accurately detected with a typical UOA.

MoS2 absolutely shows up in a used-oil test. It is obvious, especially when used with an oil that does not contain any moly, such as M1 TDT.

Yes there is, tons of it, well more like grams of it. Nice to see a UOA with MoS2 in a diesel. Who was it that always claims about MoS2 eating copper in a diesel environment?

We use an engine oil that does not normally contain any moly so it seems to show up pretty well. I've done about a half dozen more with similar results.
