Every time we maintain the car, we have to unscrew and replace an iron can like a small can on the car. This is our oil filter, which is replaced with our oil.

That's the problem. How often does the oil filter change? What is its maximum life span?

Before we figure this out, let's take a look at the oil filter.

Our current oil filters are rotary oil filters. There is a round iron box outside and folded filter paper wrapped inside. This filter paper is the core material of our machine filter. Now the machine filter paper is heat cured, so it has a certain hardness and strength. Unlike our ordinary paper, it can withstand oil pressure and is not easy to deform.

The oil filter is thus screwed in the middle of the oil circuit, with the oil pan below and the engine above. Its main function is to filter impurities and dirt in the engine oil, provide clean lubricating oil for the engine, reduce wear and prolong the service life of the engine.

How does the oil filter work?

It has an oil inlet and an oil outlet. The oil in the oil pan flows into the machine filter from the oil inlet check valve. The dirty oil flows into the machine filter at the edge of the machine filter and outside the filter paper and then filtered through the filter paper. The clean oil flows out of the center of the machine filter and is sprayed on all parts of the engine.

This is a normal working process, but there will be some special cases. For example, our machine filter takes a long time, there are too many impurities on the filter paper, and the filter paper hole is blocked, which will reduce the outflow of oil and the amount of oil entering the engine, which will affect the lubrication and operation of the engine. What should we do?

In fact, at this time, to ensure the amount of oil flowing into the engine and maintain the oil pressure, there is a spring valve at the bottom of the oil filter, called the bypass valve, which will automatically open to allow the unfiltered oil to flow in from the valve at the bottom, merge with the oil in the center of the filter and flow into the engine together, but at this time, the mixed oil is the oil with impurities.

How long can the oil filter last?

The service life of an oil filter is mainly judged according to its filtering capacity, not it's quality. If there are too many impurities and oil dirt in the engine oil, it will adhere to the filter paper and block the filter hole, resulting in low oil pressure, so that the engine oil with impurities will directly enter the engine, which is equivalent to that the engine oil has not been filtered. It is time to change the filter at this time.

Therefore, the replacement of the filter depends on the cleanliness of the engine oil. For example, for our new engine oil and filter element, if we don't change the engine oil during maintenance after 5000 kilometers, we only change the filter, but the next time we change the filter, it won't be 5000 kilometers. It may be 2000 kilometers or 3000 kilometers because the old engine oil has more impurities than the new engine oil.

Therefore, in most cases, the service life of the oil filter is 5000 km, which is aimed at new oil.
