An Oil filter is a device that removes contaminants from engine oil to improve the performance and extend the life of the engine. It is typically made of a canister filled with filter media that captures impurities such as dirt, dust, and metal particles. The filter media is typically made of paper, cellulose, synthetic fibers, or a combination of these materials. The oil filter is installed in the engine oil circuit and is designed to be easily replaced at regular intervals as part of routine maintenance. A high-quality oil filter is critical for maintaining the health and performance of an engine, and helps to prevent damage caused by dirty or contaminated oil.
