Synthetic oil is used as a substitute for lubricant refined from petroleum when operating in extremes of temperature, because, in general, it provides superior mechanical and chemical properties to those found in traditional mineral oils.emi-synthetic oils (also called 'synthetic blends') are blends of mineral oil with no more than 30% synthetic oil designed to have many of the benefits of synthetic oil without matching the cost of pure synthetic oil. Motul introduced the first semi-synthetic motor oil in 1966.
By contrast, synthetic oil is not distilled from crude oil. It is made through a chemical process known as the Fischer-Tropsch process, starting with raw materials like methane, carbon monoxide, and carbon dioxide.This process was developed by Germany in WWII, when that country's access to crude oil was very limited.his is one reason synthetic oils last so much longer than non-synthetics. The physical property used to quantify an oil's resistance to viscosity change with temperature is known as the Viscosity Index (VI). The higher the VI, the more resistant to viscosity change the oil is.
