Soot level in oil

[Lonestar10]

New engine nice and fit also a new engine design maybe they've gotten the thing to run so clean in the cylinders but dosing the hell outa the exhaust with DEF that is doesnt bring alot around in EGR for a reburn just wishful thinking.

i think around 200k and above is where i would watch it closer since the 2250 and 2350 liked to carbon pack themselves to death around that 500-600k mark which also might have to do with neglected Aftertreatments, dirty sensors, 30-40k mile oil changes... ied think you should be able to keep an engine pretty clean with mandate intact with just always doing PMs keep sensors clean/new, change oil on time. its once that 1 item get neglected causing a snowball effect down the line to where you just chase your tail everywhere.
