Semi-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.Lubricants that have synthetic base stocks even lower than 30% but with high-performance additives consisting of esters can also be considered synthetic lubricants.he technical advantages of synthetic motor oils include: 1  Better low-and high-temperature viscosity performance at service temperature extremes. 2  Better (higher) Viscosity Index (VI). 3  Better chemical and shear stability. 4  Decreased evaporative loss. 5  Resistance to oxidation, thermal breakdown, and oil sludge problems.
