Title says it all, compare to the oils in the columns to the right, they are labeled. My main interest was how it compared to Mobil 1 10w40 4T Racing.
Recap, put new high compression pistons in 10,000 miles ago, so this OCI started about 5,000 miles after pistons were installed.
I see what Blackstone says about the aluminum, however I am wondering if aluminum should be coming down more on this second major oil run after initial break-in?
Otherwise I see that it did not thicken up, which I was interested in because it thickens up in the air cooled twins, but obviously a liquid cooled engine is treating this oil differently. As well it stayed right in the middle of grade.
Zinc and phosphorus are way lower than what Mobil advertises (1750z/1600p). Can someone tell me if these are sacrificial additives or if there is simply that much variance in either the analysis or what Mobil actually puts into the oil itself?
Okay, let the collective chime in and the input begin in terms of any discussion or questions.
