Iron 8

Copper 3
Chrome 0
Lead 7
Tin 0
Sodium 11
Dirt 5
Engine Soot Light
Fuel ---
Water neg
Solids none
Glycol neg
Visc 76
TBN 7
As best I can tell it is ok to continue to run with this oil but informed expert interpretations are invited.

I believe the important number to look at in order to answer this question is the TBN. If you went to Blackstone then he should have provided a "summary" of the results with an opinion of the miles left based on the TBN. That is how I remember it anyway. Doesn't the TBN test cost extra?
