I'm assuming the universal averages listed in the oil report are based on 5000k oil change?
In fact, if they aren't adjusted to an 11,500mile oil change, then several of the results are in fact far lower then the average. As well, there is no standard deviation listed for the averages, so no real conclusion can be made here.
The iron content is still high but again, if the SD is only 3 then 14 average plus 3sd is 17 for 67%normal range. 17*(11500/5000) = 39.1 which is higher than actual of 39.
I don't think we need to change the oil more often if leaving our cars stock and daily driving it.
