The three major functions that lubricants perform are:

Reducing friction
Cooling
Cleaning


Reducing friction is what most people would think of when asked what a lubricant does. With all its parts that move quickly and very close to each other, an engine would not survive for long without a lubricant to 'smoothen things up'.

Cooling is necessary because a working engine heats up to high temperatures. Without a lubricant, it would break down from the heat it produces itself!

Cleaning concerns the impurities that exist in an engine. Combustion, the process that takes place inside an engine, produces soot and contaminants. Without lubricants these would form large deposits in the oil block passage, hindering the engine's performance as a result.
