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.

I acctually use Castrol synthetic blend 10/40 and Lucas synthetic oil stabilizer. Car hold 35 psi at idle warm and 65 psi at WOT. Have come a firm believer in the Lucas oil stabilizer.

than you believe in crap
All the lucas oil stabilizer is, is an oil thickener. You're better off just buying a thicker weight oil. Plus the lucas stuff loves to trap air in the oil, that can cause foaming. Not something you want in an oil additive.Lucas Virgin Oil Sample
