Oxidation; 15, 16, 14, 14, 13
Nitration; 10, 10, 9, 9, 8
Polaris Comments:
No abnormal findings. Resample at normal interval.
A pretty boring UOA, just the way I like it. Only thing is a developing trend with soot, but not a serious amount.
Corrected Iron wear rate is 3.1ppm per kmile. That's OK.
I changed the filter after taking the oil sample. Fram Ultra not available at WalMart, so I bought a Purolator Boss.
Plan to extend the OCI to 36,000 miles.
