This is there reply to a question about my oil analysis:

What about just using this oil at half the price it’s 5w/30.
these are high mileage engines and you don’t hear about om642’s having issues with regular recommended 5w30 changes (it’s everything else that will fall apart first )
I can’t help but think the oil examiner is upselling their own oils ?

Pardon our interruption...

Hence the question - I have been using MB 229.52 for a while now - Just wondered if the more expensive oil would be of any benefit - I guess I was willing to give it a go but @nearly twice the cost maybe not

I'm not seeing anything there to prompt a change in viscosity.
What I am seeing is concern for soot levels for which a reasonable level of detergency is required to prevent deposits and carbon build up. As your current oil is managing the soot acceptably well WRT drain interval, I can't see a need to deviate from your current oil and its viscosity.
Highish soot levels could be due to injectors not at their best - possibly in need of a clean.
Millers are offering an API CF (obsolete 1992 spec) at a price beyond market average. The oil I use is CK-4 rated. At Miller's price, I'd be looking for better than CF.

Is this an oil additive? If so, then modern oils do not need any additives, in fact it is recommended not to add anything to the engine oil.

(I used to add Molykote for years... but I no longer do)

I think it’s easy to go down the rabbit hole with oil and specs . Going with oil that meets the spec and decent make filter is the best you can do imho.
Spending a fortune on expensive oils will improve things by what tiny percentage ?
This om642 engine is well tested in cabs and sprinters to intergalactic mileage and they aren’t all using the most expensive oil .
