Synthetic Lubricants

Synthetic lubricants are man-made lubricants that are engineered to provide superior performance compared to conventional mineral-based lubricants. They are composed of artificially synthesized chemical compounds and are designed to offer better viscosity, thermal stability, and oxidative stability.

Properties of Synthetic Lubricants

Synthetic lubricants possess several key properties that make them advantageous over traditional mineral-based lubricants:

• Viscosity Stability: Synthetic lubricants maintain their viscosity over a wide range of temperatures, providing consistent lubrication performance in extreme hot or cold conditions.
• Thermal Stability: They exhibit high thermal stability, resisting breakdown at high temperatures and reducing the formation of harmful deposits.
• Oxidative Stability: Synthetic lubricants are less prone to oxidation, which helps to prevent the formation of sludge and varnish in the lubrication system.
• Low Pour Point: They have a lower pour point compared to mineral oils, ensuring fluidity at low temperatures.
• Extended Oil Change Intervals: Synthetic lubricants often allow for longer intervals between oil changes due to their superior resistance to degradation.

Applications of Synthetic Lubricants

Synthetic lubricants find applications in various industries and equipment, including:

• Automotive engines and transmissions
• Industrial machinery and equipment
• Aircraft engines and hydraulic systems
• Marine propulsion systems
• High-performance and racing vehicles
