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

The resources above cover the following skills:

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.

Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.

Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
