I used to run Swepco 20W50 in my old 3.2. No noticeable difference between that, Kendall, or VR1. I run VR1 anymore because it's readily available and less expensive. You can read the billion page oil thread as it's mentioned a few times in there. I doubt any of the regular Zinc-heavy weight-proper oils offer any meaningful advantage over the others.
