Actually some oils are truly synthetic. Piston engines use mostly synthetics and standard oils, but others like jet engines, mostly use purely synthetic oils because they have better chemical and mechanical qualities than crude derived oils do. Germany developed true synthetics during WW2 because of resource limitations.
