From Polaris labs.
Elemental Analysis:
Silicon; 15 ppm
Sodium; 11
Moly; 670
Boron; 120
Magnesium; 14
Calcium; 2469
Phos; 1221
Zinc; 1504
KV100 = 10.5 cSt
TBN = 8.55
Oxidation = 108
Nitration = 8
When I had Polaris do a UOA on Redline out of my Camaro back in March, they got oxidation and nitration numbers of 115 and 31, respectively, and flagged oxidation as severely high. But this VOA shows 108 for new oil, so they were being unnecessarily alarmist:
"Lubricant and filter change is suggested if not done at sampling time; Infrared results indicate OXIDATION is SEVERELY
HIGH; Infrared results indicate that NITRATION is at a SEVERE LEVEL; Total Base Number is MODERATELY LOW; Abrasives
(silicon/dirt) are at a MINOR LEVEL; Please submit a new lube for BASELINE REFERENCE; In order to properly compare data to
the right standards, we need manufacturer and model of the unit, and the manufacturer, type and grade of the lubricant;
Flagged data has been rechecked and confirmed;"
But one question I do have: Is an increase in Nitration from 8 to 31 cause for concern?
