Lubricants reduce friction between any two running parts which are in contact with each other. Thus they reduce wear and tear and increase the life of those parts.

An ideal lubricant should have a very high adhesion to the surface being lubricated and very poor cohesion between its own molecules so that the viscous drag is minimum.
What this means is that the lubricant should stick to the sliding parts and have a low viscosity to minimize the sliding force when the parts move relative to each other.
Incidentally, coconut oil has these properties. Unfortunately, it can become rancid and attract ants.

The molecular force between the mass of lubricant is not very strong, and it switches over to the next lump of molecules easily, that is the reason why it does not form into a solid structure. This quality is taken benefit of for applying the media to reudce he friction between the surfaces.

There are various types of lubricants. A dry film lubricant is not crushed under high pressures (see titanium dioxide). WD40 is a common one that displaces water.

Interpretive Summary: One way of countering the current oversupply of farm products relative to world-wide demand is by developing new consumer and industrial products from farm-based raw materials. Another method is by using farm-based raw materials to replace petroleum-based components in existing products. Lubricants used in various applications constitute a large new market for farm products.

Lubricants adhere to the applied surfaces and provide a smooth interaction surface.
