The oil filter is located in the lubrication system of the internal combustion engine. With the complexity of modern internal combustion engine structures, the improvement of lubricating oil quality, and the increase in additive types, new requirements have been put forward for the filtering effect of filters, and new content has also been given to the matching technology of oil filters.

When an oil filter becomes clogged, the oil factory says the filter is not good, and the filter factory says the oil is not good. At this time, we need to pay attention to judgment.

Under normal circumstances, the blockage of the oil filter is caused by various impurities in the lubrication system. But when using substandard engine oil, the gum formed by the oil itself, combined with other impurities, leads to the formation of more carbon deposits, which can easily block the engine oil filter.

So while ensuring the filtration efficiency of the engine oil filter, try to reduce the resistance as much as possible to ensure the passability of the engine oil, while also ensuring that the engine oil used is of good quality. Therefore, it is necessary to conduct tests on the original resistance pressure difference, original filtration efficiency, and blockage life of the oil filter, while also conducting a physicochemical analysis of the oil.
