I was hoping to get a TAN reading but looks like lab error. I expect TAN to be 6.0 or higher. I contacted Blackstone and they are usually pretty good about getting things straightened out so I hope to update that in the near future. TAN is important due to the test I'm doing to see what effect PCV bypass has on the oil. This 5100 mile UOA is on the same run as the 2700 mile run. The VOA I pasted into the report is from the same case of oil as both runs.
Roughly 50% highway, 50% city. Run #1 was 90% city in the winter. Please note that these UOAs are pre-pcv bypass. All comments welcome.
btw iron for this run was 3.7 ppm/1000 miles at 14,000 miles
