What is the function of the oil filter?

The oil filter plays a critical role in maintaining the performance and longevity of an engine by removing contaminants from the engine oil. As the oil circulates through the engine, it picks up dirt, metal particles, sludge, and other debris that can accumulate over time. If these contaminants are not filtered out, they can cause wear and tear on engine components, lead to increased friction, and ultimately diminish engine efficiency.

By trapping these harmful particles, the oil filter ensures that only clean oil circulates through the engine, helping to maintain proper lubrication, reduce wear, and protect sensitive engine parts. This function is vital for optimal engine operation and longevity, making the oil filter an essential component of the engine lubrication system.
