Filtration: The primary purpose of an oil filter is to remove contaminants from the engine oil. As oil circulates through the engine, it picks up dirt, metal particles, and other impurities. The oil filter traps these harmful substances, preventing them from circulating further and potentially causing damage.
Particle Size Limit: Oil filters have multiple beta ratios for different particle size limits, such as 2, 5, or 10 microns1. This means they can capture particles of varying sizes, ensuring cleaner oil reaches critical engine components.
Extended Engine Life: By keeping the oil clean, the filter contributes to longer engine life. Clean oil reduces wear on moving parts, minimizes friction, and maintains proper lubrication.
