Hmmm maybe they use Oats as the basis of Synthetic oils.
Thus my engine is Gluten free.
All seriousness aside...
German Chemists developed Synthetics in WW II.
My Guess from Coal.
Today they start with Methane , thus eliminating the Wax/Crud from Crude oil distillation
Add the magic of Chemistry to formulate a tight range specification on Viscosity.
No Wax/Crud in the burn of your oil, less Carbonized deposits in your Exhaust.
