Synthetic oil is void of organic lipids, like found in lotions. Rather polymer is added to the mix of chemicals or petroleum resulting in more predictability and control of the desired product. For example it has a higher viscosity index.
The engine management system protects the car in various ways against driving styles that would otherwise cause damage to the car. At both the engine level and driver controls. For instance 4th gear to 1st gear will not happen outside the engine envelope. I hope this helps.
