Code:
This is a reman engine that has shown somewhat high copper in every UOA since its breakin.
The first two UOAs were PU 10W30 and the last two were Rotella T6. Oil filter for sample #4 was a M1.
Unit time is time on the reman engine, not vehicle.

Polaris uses a scale of 0-4 for severity.
0 & 1 are normal, 2 & 3 are abnormal and 4 is critical.
Values flagged with a "*" are flagged for severity.
