My 2 cents:
It is interesting that they [posters at this forum] are going to such trouble, but their used oil analysis is very unscientific. One poster changes from one oil to the next in his/her engine and compares it to measurements from someone else's engine or to their old results with different mileage without regard to oil filter, leftover contaminants, oil removal method, or driving style. For example, one poster removes the oil drain plug for one measurement and uses a syphon device for another. There is no way to draw any conclusions from this.
The only meaningful test would be one with identical engines and filters running under the same temperature and load conditions for the same amount of time, each with a different oil (performed by an independent lab, not performed or funded by a manufacturer).
I have no idea how to interpret the new oil analysis and, not being a chemical engineer, I'm not going to try.
