3 Outstanding Advantages of Synthetic Lubricants

Currently, motorcycle oils are divided into three main categories: synthetic oil, semi-synthetic oil, and mineral oil. Among these, synthetic oil is considered the best type of oil for motorcycles.

So, what are the advantages of synthetic oil, and why is it favored by many? Let’s explore with Huynh Chau in the article below!

Why is synthetic oil better for motorcycles?

1. Higher flash point

What is the flash point?

The flash point is a technical parameter of motorcycle oil, referring to the temperature at which the oil begins to evaporate and ignite when exposed to a spark.

The flash point primarily depends on the viscosity of the oil. The thicker the oil, the higher the flash point, and vice versa. Additionally, the flash point is also affected by the base oil, which can help distinguish synthetic oil from mineral oil.

Oil with a high flash point not only has fire resistance and thermal stability but can also operate effectively in extreme temperature conditions.

A high flash point ensures better engine lubrication in high-temperature environments and reduces oil loss.

Why does synthetic oil have a higher flash point than mineral oil?

Synthetic oil is clean and composed of uniform molecules. Therefore, during operation, it does not produce much residue that could hinder machinery performance, and synthetic oil also has the ability to limit the combustion of oil molecules when the engine operates at high temperatures.

These characteristics contribute to synthetic oil having a higher flash point compared to mineral oil, providing better engine lubrication in high-temperature environments while minimizing oil loss.

Synthetic oil lubricates the engine better in high-temperature conditions.

2. Lower friction

Synthetic oil is produced through a synthesis process in the factory, composed of molecules with a high degree of uniformity in size and physicochemical properties, resulting in smoother movements across the surfaces of engine components and generating less friction force.

In contrast, mineral oil, made from crude oil, has molecules with irregular shapes and sizes. Consequently, it creates more friction during engine operation.

Synthetic oil, with its uniform molecular composition, helps reduce friction for the engine.

3. Higher oil stability

Before exploring oil stability, it is essential to understand the concept of "viscosity." Simply put, viscosity refers to the thickness or thinness of the oil. You may find various oils on the market with different viscosity levels, such as Repsol Moto Scooter 10W40, Repsol Moto Racing 10W50, Essenza Sintetica Scooter MB 10W30, etc. The higher the viscosity, the thicker the oil, and vice versa.
