Machine Oil

Lubricant

A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. A lubricant's effectiveness against friction is measured as its lubricity and the study of lubrication in material science is known as tribology.

Machine

A machine is a thermodynamic system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and human power, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

Oil

Oil is a liquid with varying degrees of viscosity depending on temperature. Oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic and lipophilic. Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.
