In NA cars that aren't driven hard then regular oil is fine as long as it's changed regularly but in a turbo car I wouldn't run anything but synthetic since turbos run way hotter (900+F) than anything on a NA motor and need to be cooled down after driving and synthetic resists "coking" on the turbo bearing much better than dino stuff. Synthetic also pours and flows much better at temps under 0F which is a big deal when starting your vehicle in freezing temps. Synthetic also has better heat stabilization and resistance to burning and simply gives a hard driven engine extra protection and a bit bigger margin for error of something goes wrong.
It's not marketing hype for those who will really benefit from it. With my 4Runner I just use it mostly for length between changes.
