Oil for the engine and the transmission on these ZR-1s are discussions that can go on until the end of time. It is nice to see the discussion though. I try not to lose sleep over it. You can tie yourself in knots following recommendations, counter recommendations and counters to those counters. Personally, I stick to Mobil 1 10W-30. It has worked very well for me.
