Thank you.
I bought my bike used with ~1500 miles, and the dealer told me to change the oil because they weren't sure it had been done by the PO. It shifted fine with whatever was in it. I replaced it with Mobil 1 racing 4t 10W-40 because it was readily available and it's a nice quality oil. I'd used Mobil1 in a modern Triumphs without problem. However, I don't recommend it for the CB1100. After Mobil1, the engine promptly developed a camshaft rattle down low (I gently adjusted the camshaft balancer and that helped), and it shifts a little less well. I'm coming up on the 4,000 mile oil change, and I'll probably use Honda 10W-30...but I'm tempted to get full synthetic 10W-30 motorcycle (but non-Honda) oil because it's available much closer to me than the Honda dealer.
