The 10W30 label on the bike engine oil implies that oil’s viscosity is rated at 10W when the engine oil is cold whereas 30 when it is hot. What exactly is viscosity and how it impacts the quality of the two-wheeler engine oil? Let’s find out.
What Is Engine Viscosity?
Engine oil viscosity implies the ease at which engine oil pours at a particular temperature. Thin oil contains lower viscosity and spills more easily at lower temperatures in comparison to thicker oils with greater viscosity.
Thin oil reduces friction in engines and assists engines to start promptly during the winters. Thick oils are more efficient in maintaining strength and oil pressure at high temperatures as well as loads.
Measuring The Viscosity Of Engine Oil
The SAE or Society of Automotive Engineers created a scale to measure engines as well as transmission oils.
In this, the viscosity is denoted using standard categorization ‘XW-XX.’ The number before the letter ‘W’ rates the flow of the oil at zero-degree Fahrenheit.
The lower this figure, the lower are the chances of oil getting thickened in the winters. The number proceeding X represents the viscosity at 100-degree C and denotes the resistance of oil to thinning when the temperature is high.
The Importance Of Viscosity Bike Oil
To have a standard way to measure the viscosity of engine oil, SAE or Society of Automotive Engineers developed a scale of viscosity. The scale varies from 0W, which denotes the thinnest oil type to 60, which denotes the thickest oil. The ‘W’ that you see on the oil print stand for the winter because this segment shows the level viscosity of the oil when the engine is cold.
Motor oil that is thinner can flow faster and more easily. This is vital as when you start a cold engine; the motor oil needs to lubricate the components quickly. Moreover, motor oil with low viscosity enables it to do the same. When the engine is hot, you need oil to be extremely thin. Therefore, thicker oil or higher viscosity keeps the engine parts lubricated as well as separated.
Effect Of Oil Viscosity On Equipment
Along with the motor engine, the viscosity of oil also impacts the other equipment as well. For instance, viscosity can decrease or increase the heat generated by cylinders and bearings. Viscosity can also impact how prompt oil is consumed and how efficient equipment starts and operates at high temperatures.
Using oil with higher viscosity will use less amount of oil and ensure that vehicle or equipment bear less wear and tear. However, motor oil with thinner viscosity can enhance the startup speed of different tools and reduce the usage of fuel.
The use of improper oil viscosity can result in friction between machine components. And, when this contact remains unchecked, this will result in damage in different parts. Subsequently, it is imperative not only to choose the right application but also regularly change the oil. This will ensure that the engine and associated parts continue to work properly and at their maximum efficiency.
