Base Oil Characterizes:
Base Oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil). Base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or naphthenic in nature depending on the chemical structure of the molecules.
Almost every lubricant used in plants today started off as just a base oil. The American Petroleum Institute (API) has categorized base oils into five categories (API 1509, Appendix E). The first three groups are refined from petroleum crude oil. Group IV base oils are full synthetic (polyalphaolefin) oils. Group V is for all other base oils not included in Groups I through IV. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five API groups.
| Feature | Group I | Group II | Group III | Group IV (PAO) | Group V (Esters, etc.) |
|---|---|---|---|---|---|
| Saturation Level | Low | High | Very High | Very High | Varies |
| Viscosity Index (VI) | 80–120 | 90–120 | ≥ 120 | ≥ 125 | High |
| Sulfur Content | High | Low | Very Low | Nil | Varies |
| Production Method | Solvent refining | Hydrocracking | Hydroisomerization | Chemical synthesis | Esters/synthetics |
| Typical Uses | Industrial oils, gear oils | Engine oils, hydraulics | Premium motor oils | High-performance lubes | Specialized applications |
| Cost | $ | $$ | $$$ | $$$$ | $$$$+ |
Group I
Group I base oils are classified as less than 90 percent saturates, greater than 0.03 percent sulfur and with a viscosity-index range of 80 to 120. The temperature range for these oils is from 32 to 150 degrees F. Group I base oils are solvent-refined, which is a simpler refining process. This is why they are the cheapest base oils on the market.
Group II
Group II base oils are defined as being more than 90 percent saturates less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils. Since all the hydrocarbon molecules of these oils are saturated, Group II base oils have better antioxidative properties. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.
Group III
Group III base oils are greater than 90 percent saturates, less than 0.03 percent sulfur and have a viscosity index above 120. These oils are refined even more than Group II base oils and generally are severely hydrocracked (higher pressure and heat). This longer process is designed to achieve a purer base oil. Although made from crude oil, Group III base oils are sometimes described as synthesized hydrocarbons. Like Group II base oils, these oils are also becoming more prevalent.
Group IV
Group IV base oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They have a much broader temperature range and are great for use in extreme cold conditions and high heat applications.
Group V
Group V base oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, bio lubes, etc. These base oils are at times mixed with other base stocks to enhance the oil’s properties. An example would be a PAO-based compressor oil that is mixed with a polyolester. Esters are common Group V base oils used in different lubricant formulations to improve the properties of the existing base oil. Ester oils can take more abuse at higher temperatures and will provide superior detergency compared to a PAO synthetic base oil, which in turn increases the hours of use.
What is Base Oil? Key Features and Applications
Base oil is the primary component of lubricants, forming 70–90% of the formulation in most cases. It serves as the foundation upon which additives are blended to create lubricants that reduce friction, minimise wear, and enhance the performance of machinery and engines. Derived from refining crude oil or through synthetic processes, base oils are versatile and indispensable across numerous industries.
Key Features of Base Oils:
Base oils are characterised by their viscosity, thermal stability, and ability to resist oxidation. High-quality base oils maintain their performance under extreme temperatures, ensuring smooth operations even in challenging conditions. Their low volatility reduces oil consumption, while their high purity helps minimise deposits and sludge formation in engines and equipment.
Applications of Base Oils:
The uses of base oils are as diverse as the industries they serve. In the automotive sector, they are integral to engine oils, transmission fluids, and greases. Industrial machinery relies on base oils for hydraulic fluids, compressor oils, and metalworking fluids.

Understanding Base Oil: The Backbone of Lubricants
Base oil is the cornerstone of lubricant formulations, providing the essential properties required for smooth, efficient, and reliable performance in machinery and engines. Acting as the primary ingredient, base oils make up the majority of a lubricant’s composition, with additives enhancing specific attributes like wear protection, corrosion resistance, and temperature stability.
Why Base Oil Matters
Base oils are the medium through which lubricants deliver their core functions: reducing friction, transferring heat, and minimising wear. Their inherent properties—such as viscosity, thermal stability, and resistance to oxidation—determine how well a lubricant performs under various operating conditions. For instance, high-quality base oils ensure consistent performance in extreme temperatures, whether in the heat of a manufacturing facility or the freezing cold of outdoor operations.
API Classification and Performance
Base oils are classified into five groups by the American Petroleum Institute (API):
Group I: Solvent-refined mineral oils with moderate purity.
Group II and III: Highly refined mineral oils with better oxidation stability and fewer impurities.
Group IV: Synthetic oils, such as polyalphaolefins (PAOs), offering superior performance.
Group V: Miscellaneous oils like esters and silicones used for specialised applications.
These classifications reflect the level of refining, performance capabilities, and cost considerations, making them crucial for selecting the right lubricant.
