What is a Oil filter?

An oil filter (English: oil filter) is a filter that removes sludge, abrasion powder, dust, etc. from engine oil, hydraulic equipment oil, etc. For automobiles, it is sometimes called an oil element, and it is often used in automobiles and industrial machinery. As the machine operates, the oil gradually oxidizes and becomes dirty. Continuing to use dirty oil may cause machine failure, so the oil must be filtered with an oil filter. Filtration causes dirt to accumulate in the filter, so regular replacement is required.
