As is well known, engine oil is a crucial part of car maintenance. However, there are various opinions circulating in the market about changing engine oil. So why do we need to regularly change engine oil and oil filters?? The editor has specially compiled several common questions about oil and filter replacement, as well as car maintenance. Let's take a look together!
Firstly, we need to understand: why do we need to change the engine oil???
The engine oil itself contains a certain amount of gum, impurities, moisture, and additives. At the same time, during the operation of the engine, the introduction of metal debris, the entry of impurities in the air, and the production of oil oxides gradually increase the amount of impurities in the engine oil.
Secondly, when is the most appropriate time to change the engine oil???
Our oil change time is usually based on kilometers and time. Whether we listen to experienced drivers or read the manual, they usually give us a recommended value. For example, regular mineral oil should be changed every 5000 kilometers or six months, semi synthetic oil every 7500 kilometers, and fully synthetic oil every 10000 kilometers. These standards are indeed correct, but we also need to determine according to the actual road conditions. If we add a bucket of oil with a shelf life of only three months left, even if we have not reached these kilometers, we need to replace it!
Thirdly, why is changing engine oil important for car maintenance???
Under normal circumstances, the lifespan of a car engine is generally around 10-20 years. The better the maintenance, the longer the lifespan. Engine oil (lubricating oil) plays a crucial role in protecting the engine, including lubrication, cooling, cleaning, corrosion prevention, and sealing. Only clean engine oil can accomplish these tasks.
Fourthly, what should be noted when changing the engine oil???
The function of the oil filter is to filter out impurities, gum, and moisture in the oil, and deliver clean oil to various lubrication parts. Therefore, the oil should be replaced simultaneously with the oil filter.
Fifth, what are the benefits of replacing both the engine oil and the oil filter at the same time???
Usually, changing both the engine oil and the oil filter at the same time is beneficial for grasping the oil filter replacement cycle and is also an effective way to maintain the cleanliness of the oil circuit. Technicians and consumers also have a good memory of the replacement time. Therefore, it is crucial to ensure the effective use of the engine oil and the cleanliness of the engine oil. A good oil filter makes car maintenance twice as efficient.
