The Engine Oil
Engine oil or Motor oil is oil used for lubrication of various internal combustion engines. In engines, machine parts move very closely against each other causing friction which dissipates otherwise useful power by converting the energy to heat, which could lead to lesser efficiency and degradation of the motor. This increases fuel burning up and decreases power output and can, ultimately, lead to entire engine failure.
Engine oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them and so decreasing friction, carry, and generation of excessive heat, thus shielding the engine. Motor oil also transmits away heat from moving parts, which is important because materials have a tendency to become softer and less burnishing-resistant at high temperatures.
