What is SN150?
SN150 is a Group I base oil derived primarily from crude oil through a series of refining processes. Group I base oils, including SN150, are characterized by their solvent refining method, distinguishing them from other groups.
Features of SN150
Viscosity Index
One of the defining features of SN150 is its viscosity. In technical terms, viscosity refers to a fluid’s resistance to flow. For SN150, its viscosity range typically falls between 135 to 165 cSt at 40°C. This specific range makes it suitable for a variety of lubricant applications.
Thermal Stability
SN150 exhibits excellent thermal stability, meaning it can maintain its properties even when exposed to high temperatures. This is crucial in applications like engine oils, where the oil is subjected to the intense heat of combustion.
Oxidative Stability
Oxidation can degrade oil, leading to the formation of sludge and other harmful compounds. Thanks to its high saturate content and paraffinic nature, SN150 is resistant to oxidation, ensuring a longer oil life and reduced engine deposits.
Saturate Content and Sulfur Levels
SN150 boasts a high saturated content, usually above 90%. Saturates are hydrocarbons with no double or triple bonds, making them more stable. This high saturate content contributes to the oil’s oxidative stability.
Additionally, SN150 typically has a sulfur content of less than 0.03%, which is a testament to its purity and refinement.
Colour and Clarity
Aesthetically, SN150 is typically clear and bright, with a pale yellow to amber hue. This further reinforces the oil’s purity and the absence of impurities or contaminants.
Flash Point
This is the temperature at which the oil gives off vapours that can ignite. SN150’s flash point is typically high, indicating its resistance to catching fire, a crucial safety feature.
Pour Point
The pour point indicates the lowest temperature at which the oil remains fluid. SN150 typically has a low pour point, ensuring it remains fluid in colder conditions, making it suitable for applications in varying climates.
Chemical Composition
SN150 is often termed a ‘paraffinic’ base oil due to its high content of paraffinic hydrocarbons. This gives it good oxidative stability and a clear, bright appearance.
Applications of SN150 in Nigeria
The SN150 has diverse applications, including;

Base Oil SN500 in Nigeria
What is SN500?
SN500, like SN150, is a Group I base oil. However, it’s distinguished by its higher viscosity range. Produced through solvent refining processes, SN500 is derived from crude oil, undergoing a series of treatments to achieve its unique properties.
Features of SN500
Viscosity Index
SN500’s defining characteristic is its higher viscosity, which ensures a thicker oil film with its typical range of 485 to 515 cSt at 40°C. This thicker consistency makes it suitable for applications that demand a more viscous oil. This is particularly beneficial in applications where a robust lubricating film is essential to prevent metal-to-metal contact and wear.
Saturates
SN500 has a high ‘saturate content’ (hydrocarbons with only single bonds). This high saturate content contributes to the oil’s stability, ensuring it resists oxidation and maintains its properties over time.
Sulfur Content
The sulfur content in SN500 is typically less than 0.5%. While slightly higher than SN150, it’s still relatively low, indicating a good level of refinement. Lower sulfur levels are beneficial as they reduce machinery’s corrosive wear risk.
Paraffinic Hydrocarbons
SN500 is rich in paraffinic hydrocarbons, characterized by their straight or branched chain structures. This gives the oil good oxidative stability and a clear appearance.
Aromatics
Present in lower concentrations, aromatics in SN500 influence specific properties like solubility and seal compatibility. Their presence is carefully managed to ensure the oil’s overall performance.
Thermal Stability
SN500’s ability to maintain its properties even when exposed to high temperatures is a testament to its thermal stability. This property is crucial in applications like engine oils, where the oil is subjected to the intense heat of combustion.
Oxidative Stability
Oxidation can degrade oil, leading to the formation of sludge and other harmful compounds. SN500’s high saturated content and paraffinic nature make it resistant to oxidation, ensuring a longer oil life and reduced engine deposits.
Pour Point
The pour point of SN500 is indicative of its ability to remain fluid in colder conditions. A lower pour point ensures the oil can be used in varying temperatures, making it versatile.
Flash Point
SN500’s flash point is a measure of its resistance to ignition. A higher flash point indicates that the oil is less likely to ignite, a crucial safety feature, especially in high-temperature environments.
