If you ask 10 guys what they use you will get close to 7 different oils. This just tells me we are overthinking the whole scenario.
Exactly right!!
The fact that there are so many combinations that work fine is a great thing for all of us, especially the beginners amongst the group. Doesn't make a hill of beans difference if one uses full synthetic, part synthetic or full dyno, as long as the oil chemistry is well proven and oil amount is adequate.
I've not used anything besides the BelRay MC1 at 1:50 ratio (another way to say this is 2% oil BTW; 32:1 is 3% oil, 40:1 is 2.5% oil, etc) starting at break in and beyond. It's a terrific combination for my engines. I don't doubt that using dyno oil for break in settles things down quicker, but so what? I figure it this way, I'm gonna fly the flights regardless and get the engine the time it needs no matter what. So what's the point of different oils for break in and general running?
