Very nice numbers and if it were my motor I would take their comments regarding the 12ppm Fe to heart, that is, not worry one bit and go on with life.
That one fellow with the 5W-40 comment made an impression on me because the data clearly show your 5W-30 is working, so I see no point in any opinions after that. Data are first and last word.
Nice data, good oil and filter choice proven.
Thanks very much for posting. This is one more thread to which we can link when the "what oil" question comes up yet again.
