Hello friends!
Since Jan 2011 my car is post-guarantee one. So I switched to less expencive oil and started tests. The reasons of the tests - to understand the possibility to use local lubricant and find out the right OCI. Unfortunatelly i did not take M1 0W-40 for the test. But I assume that previous OCI=9450 miles was too high because of significant decreasing of TBN after 60 miles on new oil (too high oxidation of M1). At the same time there was no significant TBN decreasing after 2nd OC.
Another point - wear is higher in winter period that is not news)))
