Man, how could you leave out so many good ones and claim because it's not those THREE choices, we don't care lol
Valvoline for me. I generally use 10w30 in GM V8s. I've never used Synth or Synth Blend, but I've used Max Life (High Mileage).

I like to run extra virgin olive oil...
No I actually just run Castrol GTX 5w30. I was going to switch over to synthetic back when the engine reached 10k but I asked G-Force Motorsports they said all they run is conventional oil in their Lt1s so I stuck with it. No problems, no leaks, oil change every 3k and have around 12k since the rebuild.
