Does Premium Unleaded gas do anything to improve my performance? I drive an '06 Acura RSX base?

I have a company gas card, so running on premium isnt a problem for me financially, but i'd like to know for sure if its really helping my car to run on it or not. I drive a 2006 Acura RSX base model, 155hp 4 cyl auto. It isnt hurting my engine right?
