one of the first things to consider when you want to choose an engine oil for your bike is the grade of oil.
Different numbers and letters make it only more confusing, but don’t worry we have provided this guide.

But first, let’s reach a better understanding of engine lubricant and lubrication.
Both humans and robots have a variety of characteristics in common.
Motorcycles, like all other machines, require a medium to function at their highest levels and according to their qualifications.
Engine oil, or lubricant as they like to call it, is entirely responsible for the smooth and problem-free running of a motorcycle's engine, much as blood gives us humans a new lease of life.
Engine oils play a significant role in engine life, lifespan, overall performance, efficiency, and NVH levels.
These engine oils have several distinct features.
What are the characteristics of engine oil? The engine lubricants contain a variety of qualities and characteristics that are necessary to perform so many multifunctional duties.
Motorcycle motor oils typically include hydrocarbons with 18 to 34 carbon atoms per molecule.
Because of the strong affinity of carbon, engine oil exhibits the necessary superior withstanding properties.
The viscosity of the engine lubricant, which may be thought of as the thickness of the oil flow or the flow resistance measured, is the first and most crucial feature to be considered.
Engine oil has to be sufficiently viscous in order to circulate the engine's components as well as to provide a thin layer of lubrication between moving neighboring engine parts.
The viscosity index of this engine lubricant, which predicts how the viscosity of the oil will change in response to temperature changes, defines the viscosity of this lubricant.
Even at the lowest temperatures, the engine lubricant must be able to flow to ensure that there is little to no contact between the metal parts.
The pour point is defined as the lowest temperature at which lubricating oil ceases to flow or freezes.
According to SAE regulations, the "Cold Cranking Simulator(CCS)" and the "Mini Rotary Viscometer(MRV)" are the pour point attributes needed to specify the motor oil in extremely cold temperatures.
Additionally, the oil tends to burn if lit because of the strong affinity of carbon.
The lowest temperature at which oil ignites is referred to as the flash point.
The flash point should be as high as feasible for an effective engine lubricant.
Oil serves as the engine lubricant, hence it can be either acidic or basic in nature.
In this circumstance, total base number (TBN) and total acidic number are taken into account.
The oil's capacity to neutralize bases is measured by TAN, whereas its capacity to neutralize acids is measured by TBN.
what are all the types of engine oil?
It seems to reason that the engine oils should respond differently under various circumstances given these many and varied variables.
We now have a numerical code system, which fundamentally represents the behavior of oils based on their viscosity properties via different gradings, as a result of the observational research conducted by the Society of Automotive Engineers (SAE).
These viscosity gradings vary from a viscosity of zero to the viscosity index of sixty: zero, five, ten, twenty, twenty-five, thirty, forty, or sixty.
The viscosities of 0, 5, 10, 15, and 25 each include a suffix of "W," suggesting that they are intended for use in "winter" circumstances or colder temperatures.
Depending on the temperature, the viscosity of 20 is either available with or without W.
The SAE J300 manual defines the viscometrics of these various grades of engine lubricants.
The grading of engine lubricants is separated into two categories: Single Grade - The engine oils covered by this section have 11 viscosity grades, of which 6, which come before W, are deemed to be low-temperature lubricants.
The 11 grades are 0W, 5W, 10W, 15W, 20W, and 25W for cold weather and 20, 30, 40, 50, and 60 for warm weather.
Using the Cold Cranking Simulator (ASTMD5293) and the Mini Rotary Viscometer, the dynamic viscosity of the oils with the "W-suffix," or single winter grade oils, is determined (ASTMD4684).
Likewise, the dynamic viscosity of the single non-winter grade oils is determined at a temperature of 100 °C.
Higher viscosity corresponds to a higher SAE viscosity grade.
Multi Grade - In the majority of modern automobiles, the engines are exposed to the most extreme weather conditions and temperatures.
The engine must function flawlessly both in warm and cold climates under such circumstances.
Viscosity index improvers are additives that are added to engine oil to make it operate effectively in such variations.
As a result, there are two types of engine oil: winter and non-winter, allowing for the use of just one kind of oil throughout the year.
There are often two grades involved in such oils' SAE classification.
For instance, if the oil is labeled as 10W-30, the first number, 10, denotes the oil's viscosity at lower temperatures, while the second number, 30, is showing the oil viscosity at 100 centigrade.
