I would agree that Complex Esters are the state-of-the-art, and most top-tier synthetic oils use complex esters. Motul does not have the upper hand on complex synthetic and natural esters.
What I am saying is, "So What!" They are not the only company using Complex Esters.
Complex esters are made by two methods:
1. at the reaction level by mixing various acids with one or more alcohols resulting in a Complex Ester as the finished product. Natural or synthetic acids may be used here.
2. Mix various finished esters together at an elevated temperature to generate an ester "Mix" or Blended Ester product.
Most polyol esters are in the "tri-ester" class, such as trimethylpropane TM and trimethylethylelene TME. Pentaerithritol and di-pentaerithritol are polyol esters as well.
BTW, a Complex ester could contain polyol esters and diesters.
