Performing so many multi-functional tasks needs a lot of strengths and attributes, and the engine lubricants have a series of them. At such elevated temperature conditions, the engine lubricant with a higher viscosity index proves to be beneficial. Usually, in the petrol-operated engine of a motorcycle, due to the repetitive to and fro motion of the piston inside the cylinder, the top piston ring causes the engine oil temperature to expose to temperatures as high as 160☌.

In addition, many engine lubricants come with detergents as well, which when being flowing with the oil, keeps on cleaning the engine and keeps it free from the formation of any kind of oil sludge, by trapping the soot formed from the combustion of fuel in itself.Īpart from all these prime objectives, as an additional serve, the engine lubricant also acts as a coolant by keeping the engine temperature in control under high load conditions by its flowing action. The ever-flowing action of the lubricant also keeps the internal components of the engine coated with the lubricant, thus acting as a layer between the surface of the component and atmospheric oxygen, thus preventing corrosion or formation of rust even at higher temperatures. This film avoids the direct contact between these two components by a fair margin, which finally results in decrease in the amount of heat produced due to friction, thus increasing the protection factor of the engine. This engine oil acts as a savior by creating a very thin film, which separates the surfaces of the two components moving adjacent to each other. It is in this place, where the engine lubricant comes in action. This friction, generated repeatedly, wears up the mechanical components within a particular period of time, which may lead to depreciation in the efficiency, performance and life of the engine, ultimately resulting in lower power output and fuel consumption than the desired ones. The motion between them generates a lot of frictional energy which is nothing but the heat generated from the kinetic energy of the moving components. Scientifically speaking, inside an internal combustion engine of a motorcycle which runs on a fossil fuel like petrol or diesel, there are several small or big components, which are in motion with respect to each other. The motor oil/lubricant for motorcycles performs the same operations and functions as they do in other machines and engines. The basic objective of adding the engine oil or lubricant is not a hidden science. The base oil may contain esters up to 25% for aided performance at peak power conditions of the motorcycle engines. Nowadays, the motor oils being used are mainly made up by blending a hydrocarbon base oil and various chemical olefins, which generally comprise of carbon and hydrogen as the main constituents. Lastly, it also keeps the soul of the engine ‘cool’ by keeping the temperature of the engine as low as possible, but in a satisfactorily operating condition, by absorbing all the dissipated heat generated by the movable parts of the engine.īasically, being a semi-solid or a liquid in nature, the engine lubricants for motorcycles are derived from chemical compounds, which are based on petroleum or non-petroleum synthesized products. It increases the probability of the engine’s better performance and prolonged life by avoiding the corrosion, as it keeps the internal surface of the engine always in a wet state. Apart from this aim, thanks to its sticky and flowing nature, it also cleans the dirt, dust or any other alien particles which get clogged on the internal surface and boundaries of the engine. The primary objective of this particular oil is to reduce the friction between the parts of an engine which are in motion and thereby increasing the life by reducing the wear. In effect, it is that oil, which is commonly used for better performance and smooth operation as it lubricates the internal parts and components of the engines of the motorcycles. In a layman’s words, the engine lubricant, or engine oil as it is most commonly known as, is a liquefied substance which has an oily character to it. Let’s cover up them one-by-one:-Ĭall it, whatever you want it. There are several characteristics which these engine oils come along with. The longevity, overall performance, efficiency, NVH levels and life depends a lot on the engine oils. Just as the blood acts a flowing lease of life for us humans, the engine oil, or lubricant as they say, is thoroughly responsible for the smooth and trouble-free operation of the engine of a motorcycle. Being a machine, motorcycles too need a medium through which they can operate in their best standards and up to their credentials. There are a number of traits which both the human beings and machines share in common.
