Was the point of your post to be pedantic? The molecular change that the basestock undergoes in the GTL process to make Group III constitutes a synthetic end product in the eyes of most people. It is a completely man made process not found in nature with a end product that cannot be duplicated by natural means. More importantly, a Grp III performs as well as Grp IV or Grp V based oils in every meaningful way.
