The answer is simple.
Use a 10W-30 or a 5W-40 in your S2000, and the engine will be just fine.
I would ignore those recommending other grades, since I doubt that they have the experience in designing and building high revving fours that Honda does.
Honda had a reason for the oil grades it specified.
Use those recommended grades and sleep easy.
Ignore the internet experts, since in this case, you really do have a highly stressed engine.
Has there ever been a normally aspirated car engine with higher specific output that you could buy off a dealership floor?
I'm with you. I agree. I was just believing someone could truly explain (and not just speculate) why Honda chose the 10w-30. I'll do more googling....
