The primary function of an oil filter is to clean the engine oil by removing harmful
contaminants. It consists of a mesh-like filtering material, usually made of fine fibers
or a combination of fibers and synthetic materials. As the engine oil passes through the
filter, particles like carbon buildup, dirt, and metal shavings are captured. This
prevents these impurities from causing excessive wear on engine parts, leading to
improved engine longevity and performance. In addition, an oil filter helps maintain
proper oil circulation within the engine, which aids in the cooling and lubrication of
engine components.
Another important aspect of oil filters is their design, which can vary depending on the
two-wheeler manufacturer and model. Some bikes use a screw-on type filter, while others
have a cartridge-based design. The filter’s efficiency and ability to trap contaminants
depend on its design, material, and the mesh size. A high-quality oil filter can
effectively trap even very fine particles, keeping the engine oil cleaner for longer
periods and reducing the overall need for oil changes. However, an inferior quality or
clogged filter may cause reduced engine performance or an increase in engine
temperature.
