Lubrication is the second name of controlling friction, wear and tear, or resistance by introducing a friction-reducing agent between sliding or moving surfaces that came across contact with each other. This lubricating agent might be a fluid, solid, or plastic substance.

As to reduce friction between surfaces in mutual contact, a lubricating agent is bound to reduce the heat produced with the mutual contact of the surfaces. It also transmits forces, transports foreign particles known as sludge, and deal with the heating or cooling of the surfaces. This property of reducing friction and tackling heat is known as lubricity.

Lubricating oil or lubricating fluid is a class of oils used to reduce friction and heat among moving or sliding components or a machine that is in contact with each other. These oils are used in all sorts of vehicles and are commonly known as motor oil and transmission fluid.

Types or categories

Talking about the types or categories of lubricating oils, there are two main categories. One is mineral oils and the other synthetic oils. Mineral oils are those lubricating oils that are refined from natural, extracted crude oil which is a mixture of a lot of substances. Whereas, Synthetic oils are lubricating oils that are manufactured artificially. Mineral oils are the type that is used more often and with large applications. This is because it caters to the low cost of extracting the oils from naturally occurring crude oil. Moreover, mineral oils could also be manufactured with varying viscosities. This implies that you can extend its application with different viscosities and different needs. This character makes this class useful in a wide range of applications.


You can also blend different viscosities of lubricating oils. This ability to blend different viscosities make it even more useful. The most commonly used motor oil could be a blend of low viscosity oil that allows easy starting in cold environments and a high viscosity oil provides better performance during normal running temperatures.

Talking about the formation of lubricant oils, they contain 90% base oil that are petroleum fractions, also known as mineral oils, and less than or equal to 10% additives. These base oils might include Vegetable oils or synthetic liquids such as hydrogenated polyolefin, esters, silicones, fluorocarbon, etc. The additives are added to deliver less friction and guarantee less wear, increase the viscosity of the oil and improve viscosity index in return, resist well to corrosion and oxidation while running of the engine, and provide less aftermath of aging or contamination, etc.

With a better understanding of lubrication and lubricating oils, it will be easier to choose the right lubricating oil for your vehicle. Lubricating is, in fact, a process of separating surfaces and protecting them to reduce friction, generate less heat, restrain wear and provide efficient energy consumption. This is done with the use of lubricating oils, greases, or other fluids. There is a need to pick the right one that is recommended by your vehicle manufacturer because that is what meets the requirements of your engine.
