The lubrication of IC engines is required to reduce tear, vibrations, over heating, and cleaning. The lubrication of IC engines has the following advantages :

1.    It reduces wear and tear of the moving parts.

2.    It damps down the vibrations of the engine.

3.    It dissipates the heat generated from the- moving parts due to friction.

4.    It cleans the moving parts.

5.    It makes the piston gas-tight.
