Generally speaking, there is no fixed replacement cycle for the engine oil filter. It mainly depends on the replacement cycle of the engine oil. When the engine oil is replaced, the engine oil filter will be replaced. The reason why the oil filter needs to be replaced every time the oil is changed is that impurities in the oil may accumulate on the oil filter, and the oil filter is a rubber product. If the oil is removed and replaced before it is installed, it may be deformed and work abnormally.

Oil is generally divided into mineral oil, fully synthetic oil and semi synthetic oil. The mineral oil usually needs to be replaced after half a year or 5000 km. Semi synthetic oil generally needs to be replaced after 7 to 8 months of use or 7500 km. Fully synthetic engine oil generally needs to be replaced after one year or 10000 km.

Is it harmful to change the engine oil too often
If the engine oil is changed too often, it will hurt a little. The oil film inside the engine takes a certain time to form. After it is formed, the effect of lubricating the engine with oil will be better. If the oil is changed too frequently, the oil film will be re formed before it is formed. The car owner only needs to change the engine oil according to the specified change cycle. After all, the cost of changing the engine oil too often is high.

If the oil of the vehicle is lower than the lower limit, it cannot continue to drive. If the engine oil is lower than the lower limit and the vehicle is still running, it will cause great damage to the engine and even damage the engine in serious cases. Engine oil is very helpful for engine lubrication. Too little engine oil will lead to insufficient engine lubrication, which will cause greater loss to the engine. In addition, the heat dissipation function of the engine can not work normally, which will lead to engine overheating. The engine may be burned over a long period of time, which is very dangerous for the personnel in the vehicle. If the car owner finds that the oil level is below the lower limit, he should quickly find a safe place to stop and call for help.
