Part of the problem here that hasn't even been touched is different oil brands. None use the same additive packs. You compare M1, Amsoil, Rotella, Motul, Driven, etc... and results will vary even with sticking to the same listed viscosities.
Like most 'what oil should I run' threads, it becomes a hair-splitting train wreck at some point, and there just is no one answer fits all. I will say it every time, get an analysis done if you REALLY want to know what oil is going to provide optimized results for YOU; your driving style, level of mods, environment, track/event type, engine wear, fuel, etc...
