In North America, did Amsoil really have the first synthetic oil? I find it amazing that a small company beat a huge Mobil corp. to the punch. I'm curious as to how Amsoil did this because they are a blender? We know they buy there supplies from various vendors, so what exactly made Amsoil the first in synthetics is interesting. Another thing, does Lubrizol make a PAO base oil or are they just an additive company? Intersting stuff here.
