How to distinguish the quality of a motorcycle oil filter

The quality of a motorcycle oil filter can be thoroughly assessed by examining its appearance, filter paper, sealing ring, brand, and price. The following are the specific methods for distinguishing them:

Visual inspection

High-quality filter: the font is clear and neat, the surface is smooth and burr-free, the paint is even and solid, the packaging is complete, and it comes with an anti-counterfeiting code.

Bottom filter screen: nonexistent font, rough surface, paint that peels off easily, simple packaging, no anti-counterfeiting logo.

Quality of the filter paper

High-quality filter paper: the pores are fine and uniform; the material is professional filter paper, the filtration effect is excellent, and it’s not easy to tear.

Bottom filter paper: the pores are rough and uneven; most of them are made from cheap cotton pulp paper, resulting in poor filtration performance and easy tearing.

Sealing ring and structure

High-quality sealing ring: good elasticity and strong sealing performance to prevent oil leaks. Low-quality sealing rings are prone to aging and deformation, leading to sealing failure.

Key components (such as bypass valves and springs): high-quality filters use metallic filters or springs with high elasticity, while lower-quality products may use low-grade materials.

Brand and price

Products from well-known brands or regular manufacturers are given priority, and quality is more reliably assured.

The filter that is too cheap may have material or process defects.

Filtration accuracy

Motorcycles typically use precision filters with a rating of 5–10 microns, which must ensure the filtration of particles larger than 30 microns.
