Today, modern engine oils offer a variety of formulations tailored to specific engine requirements, providing superior protection, efficiency, and extended service intervals.
Composition of Synthetic Oil
Synthetic oil consists of carefully engineered base oils and additives. These components are designed to provide better performance and protection compared to mineral oils.
Synthetic Base Oils
The primary component of synthetic oil is the base oil. Synthetic base oils are created through chemical synthesis, allowing for precise control over molecular structure. Polyalphaolefins (PAOs) and Esters are common types of synthetic base oils. PAOs are highly stable and provide excellent lubrication at extreme temperatures.
- Polyalphaolefins are derived from the polymerisation of alpha-olefins.
- Esters are formed by reacting acids with alcohols, offering superior solvency and lubricity.
Synthetics reduce friction, withstand oxidation, and maintain viscosity across a broad temperature range, translating to less wear and improved fuel efficiency.
Additives in Synthetic Oil
Additives in synthetic oil enhance performance and protect engine components. Common additives include dispersants, detergents, anti-wear agents, and corrosion inhibitors. Dispersants help keep engine surfaces clean by suspending particles. Detergents neutralise acids and prevent deposit formation.
- Anti-wear agents like zinc dialkyldithiophosphate (ZDDP) form a protective layer on metal surfaces.
- Corrosion inhibitors protect against rust and oxidation.
Additives work synergistically with the base oil to improve thermal stability, reduce sludge buildup, and extend oil life, ensuring your engine operates smoothly under various conditions.
Composition of Mineral Oil
Mineral oil primarily comes from refined crude oil and contains various additives to enhance its performance. These additives play a key role in protecting your vehicle’s engine.
Origin of Mineral Base Oils
Mineral base oils are derived from the refining process of crude oil. Crude oil is extracted from the earth through drilling. The refining process involves distillation, which separates the crude oil into different fractions.
One of these fractions is then treated to remove impurities such as sulphur and nitrogen. The result is a clear and stable base oil that serves as the primary component for mineral motor oils.
Additives in Mineral Oil
Additives are essential for enhancing the performance and longevity of mineral oil. Common additives include detergents, dispersants, anti-wear agents, and antioxidants. Detergents help clean and prevent deposits on engine parts. Dispersants keep particles suspended in the oil, preventing sludge formation.
Anti-wear agents such as zinc dialkyldithiophosphate (ZDDP) protect engine components from excessive wear. Antioxidants prevent the oil from oxidising, maintaining its effectiveness over time. The combination of these additives ensures that mineral oil provides adequate lubrication and protection for your engine.
