Greatful for any tips.
I thought that perhaps it would be good to go back to the original question, given that we have taken this topic all over the map.

steelgray:

I have read similar articles, but they are somewhat narrow in focus. There simply isn't one answer.

The makers of some of the synthetic and Moly-type products used to suggest that regular oil be used prior to using their oil, to promote proper bedding in of rings, etc. There may be a linkage to that theory.

The Society of Automotive Engineers is a pretty good source of unbiased info. A paper was presented at the 2006 World Congress on aged oil vs new oil, and how certain wear characteristics improved with the aged oil. This may be the link you are looking for. I have let my SAE membership lapse, and so can't get the full paper without paying full list for it, but here is the abstract:
