What is the purpose of an oil filter?

The purpose of an oil filter is to remove contaminants from the engine oil, ensuring that the oil remains clean and free from harmful particles. The engine oil plays a crucial role in lubricating various moving parts of the engine, reducing friction, cooling components, and preventing wear and tear.

Over time, the engine oil can become contaminated with dirt, metal particles, dust, sludge, and other impurities. If these contaminants are not removed, they can circulate within the engine and cause damage to vital components. The oil filter acts as a barrier, capturing and trapping these contaminants as the oil flows through it.

By removing impurities, the oil filter helps maintain the oil's viscosity and lubrication properties, promoting efficient engine performance and longevity. It helps prevent premature engine wear, reduces the risk of component damage, and contributes to overall engine cleanliness.

Regularly replacing the oil filter during routine oil changes is essential to ensure continued filtration efficiency and proper engine protection.
