2019 Ram 2500, Cummins 6.7L, 15K OCI, 59K engine

[TXHunter]

2nd oil change in the new to me Ram and things look quite a bit worse. Curious did anyone else see something similar from 'Flux' as part of the initial engine break-in period, or is this something to be concerned about? No issue with coolant levels, and have never had to any coolant to the engine.

Oil was drained at the time of the sample and switched from Amsoil 10w30 HD to the Amsoil 10w30 Signature series for diesel. First oil change below (14.5K) was from the dealer and what I would assume to be Vavoline 10w30.

Get rid of it!

My understanding is that brazing flux used in the intercooler can make its way into the engine and cause the high potassium readings. This has caused actual engine problems on some engine models. I wouldn't be surprised if it causes wear to the pistons, rings, and liners as it works its way into the crankcase.

The first thing I'd do is cut the oil filter open to check for larger metal particles. If the engine is still on warranty, start a paper trail. Lifter failure is pretty common on these engines.

Check out this thread about a TSB for the 2019+ 6.7L. Cummins seems to think that certain oils can cause engine damage. I'd ditch the Amsoil and use one of the oils specifically recommended by Cummins. I doubt the oil is the problem, but I'd still try to rule it out.

use 5w40 rotella and go with a 10,000 mile oil change, before going back to 15,000 mile changes

Not good but don't hang your hat yet. Get some 40 grade in there, cut to 7500-10k, & keep testing. If it's get's much worse than this or continues at this rate take it in for further look? Warranty?

Potassium will wash out in time, move to 5w40 as suggested and no more than 10k changes. I prefer the higher HTHS of a 40 weight over 30., some like 30 weight and have good results. My dealer provides Rotella T5 10w30 as there standard change, with Rotella T6 5w40 being the optional upgrade $$$.

Any fuel additives run??

You ran that oil for 14 months ? Try the 5-40 for 7-7500 miles and check it again. I would also use ALS or Cummins for the analysis to get better analysis of fuel dilution percentage. 15K is the limit on OCI not a recommendation.

2019 is the first year for the Engines with the hydraulic lash adjusters..
so they spec either a 10w30 CK4 oil that meets the CES 20086 standard or you can use a 5w40 that meets the same specs.
Cummins stretched out the oil drain intervals on the newest engines( 2019+) but their old recommendation for many years was every 6 months, 500 hours or 15000 miles... seems to me it would be better to do it too soon than to leave it too long.

I don't know the answer to your flux problem, but it could still be wearing in so I would just try going to a shorter OCI and sampling and see if it starts to improve..

you can see by the TBN # the oil is pretty much used up, so shortening the drain interval should help.

also worth saying Amsoil is sort of a waste of money for a what is ultimately a farm tractor engine, and you'd save yourself some coin
with no ill effects so try sticking with the old standby's like Rotella,Delvac,Delo or Premium Blue in either 10w30 or 5w40.
