Just received Blackstone analysis. Copper is still elevated at 24 but down from 37 at last change. Replaced turbo but still some residual copper HOPEFULLY...
All else looks good briefly...
IRON 24
ALUM 3
LEAD 1
SILIC 5
Moly was healthy at 100. Everything was at universal averages or less except the copper and Potassium jumped to 20 where my average was 4. They said they don't think its from antifreeze and they are seeing this more with these engines...? My coolant level is always the same.
TBN is 6.9 on 6000 miles with ValvPremBluSyn 5w40.
In your opinions, how much longer should I run the oil?
Any explainations on the potassium?
Thanks...
