Synthetic oil is a type of engine oil that is artificially made from chemical compounds. Unlike conventional oil, which is derived from crude oil, synthetic oil is made through a chemical process that involves the combination of various compounds. This process results in a lubricant that has better performance and protection properties than conventional oil.
The base material used to make synthetic oil is usually distilled crude oil, but it undergoes a chemical modification process to produce the final product. The process involves reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group, most commonly from carboxylic acids and alcohols. The resulting synthetic oil is a highly refined lubricant that has better high and low-temperature performance, resistance to oxidation and thermal breakdown, and avoids some oil sludge issues.
Overall, synthetic oil is a superior lubricant to conventional oil, offering better engine protection and performance. Understanding what synthetic oil is made from can help drivers make informed decisions about which type of oil to use in their vehicles.
Fundamentals of Synthetic Oil
Definition and Composition
Synthetic oil is a man-made lubricant that is formulated using artificially made chemical compounds. It is designed to provide superior performance and protection for modern engines.

Synthetic oil is a man-made lubricant that is created by chemically modifying petroleum molecules. The production process of synthetic oil involves several steps, including the selection of base oils, synthesis of synthetic oil, and additive integration.
Base Oils and Their Categories
The first step in the production of synthetic oil is the selection of base oils. Base oils are categorized into five groups, namely Group I, Group II, Group III, Group IV, and Group V. Group I base oils are the least refined, while Group V base oils include synthetic esters, polyalkylene glycols (PAGs), and other specialty fluids.
Group II and III base oils are the most commonly used base oils in the production of synthetic oils. Group II base oils are manufactured through the distillation of crude oil, while Group III base oils are manufactured through a hydrocracking process.
Group IV base oils, also known as polyalphaolefins (PAOs), are synthesized through a process called catalytic synthesis. Group V base oils, on the other hand, are manufactured from a variety of raw materials, including synthetic esters, polyglycols, and others.
Synthesis of Synthetic Oil
The synthesis of synthetic oil involves the chemical modification of base oils to create a lubricant with superior performance characteristics. The most common method of synthesizing synthetic oil is through the use of PAOs, which are synthesized using a process called catalytic synthesis.
During the synthesis process, the molecular structure of the base oil is modified to create a uniform, tailored molecular structure. This results in a lubricant that is more stable, has a higher viscosity index, and provides better protection against wear and tear.
Additive Integration
After the synthesis of synthetic oil, additives are integrated into the lubricant to enhance its performance characteristics. Additives are blended into the synthetic oil in the form of additive packages, which contain a mixture of several different additives.
Additives are used to enhance the lubricant’s performance characteristics, such as its viscosity, thermal stability, and resistance to oxidation. Some common additives used in synthetic oils include detergents, dispersants, anti-wear agents, and friction modifiers.
In conclusion, the production process of synthetic oil involves the selection of base oils, synthesis of synthetic oil, and additive integration. Synthetic oil is created through the chemical modification of base oils, resulting in a lubricant with superior performance characteristics. Additives are then blended into the synthetic oil to enhance its performance even further.
