Lugnutz, not sure it makes a lot of difference between name brands. Based on machine shop recommendations, I started using Brad Penn break-in oil years ago, now marketed as Penngrade1.
Brad Penn was formed when the former Kendall refinery in Bradford, PA was sold about the time that Phillips 66 purchased the Kendall brand. Their marketing tag line was (and still is) the "original green oil" harkening back the former Kendall GT-1 oils from that refinery. I had good luck with the old Kendall products, back to the '60s (Kendall-branded products manufactured by Phillips may be fine, but they are not the same), and perhaps out of a bit of nostalgia have stayed with the Brad Penn / Pengrade1 "green oil" as my regular service oil, as well.
Anyway, I've had good luck with the 30 wt. Brad Penn / Penngrade 1 break-in oil, which is high in zinc and phosphorus.
