Yes, there are benefits. It more evenly coats engine components and thus reduces wear. It also remains stable at a molecular level for a much longer period, which also reduces engine wear.
It's designed to make engines last longer and be able to run them harder. It's good for any car engine. not just performance vehicles. :)
