Good details. I've used a bit of most for the 0320 in my Warrior. I bought 2 cases of Phillips 66 20-50 last Summer at Airventure. I usually add 1/2 a pint of Camguard. More important than brand of oil is flying the plane routinely, no sits over 2 weeks. At the lower temps some type of preheat is key too.
