I don't know what the rest of the wear metals look like but if it were my decision I'd dump the KN's. They're the logical culprit for the high Si and Fe numbers. The low TBN is scary...a month or two of short haul Canadian winter driving and that oil fill would have no acid-neutralizing capability whatsoever. Based on TBN alone I think the M1 0W-40 would be a better alternative for your driving.
