LAST UPDATE TO THE QUESTION!!
I enjoy working on my cars and don't mind wasting a couple bucks if some good may come of it. What do you guys think of "Break-In Additives"? Red-line makes an additive that is safe to add to any oil at any time. Using half the bottle it essentially boosts the Phosphorus by 763ppm and the Zinc by 920ppm.

I wonder if draining the OEM oil and replacing the filter ASAP to get rid of any metal shavings and then adding good oil and the Redline break-in additive would be beneficial in the long run.
Like I've mentioned I typically try to get 300k miles out of my vehicles. Anything I can do from day 1 to help that is not wasteful IMO, especially because I have fun doing it.! Thanks everyone!
