As the lifeblood of the engine, car oil plays a vital role in the operation of the car. Engine oil is not only a lubricant for all engine components, but also cleans the inside of the engine, cools the engine components, reduces wear and friction, and extends the life of the engine. Since engine oil is subjected to harsh environments such as high temperature and high pressure during the operation of the car, it is essential to change the engine regularly to maintain the healthy operation of the car engine.
Although oil plays an important role in engine operation, many car owners have questions about the oil change interval. How often do I need to change my oil? Which kind of engine oil is better?
The role of motor oil:
Automotive oil plays a vital role in engine operation, including lubricating engine parts, cleaning the inside of the engine, cooling engine components, and reducing wear and friction. By forming a lubricating film, the oil effectively reduces the friction and wear between engine parts and prolongs the service life of the engine; At the same time, the ability to adsorb and suspend dirt helps keep the inside of the engine clean, preventing the formation of carbon deposits and deposits; The oil also cools the engine components by circulation, effectively reducing the operating temperature of the engine, improving the efficiency and performance of the engine.
There are several types of oil:
Fully Synthetic Motor Oil:Synthetic motor oil is made by chemical synthesis, and its molecular structure is more uniform and stable. Synthetic motor oils have excellent high-temperature oxidation resistance and low-temperature fluidity, making them suitable for use in high-performance engines and extreme environments, and are relatively expensive.
Semi-synthetic motor oil:Semi-synthetic motor oil is a mixture of synthetic and mineral motor oils, combining the best of both. Semi-synthetic engine oil has certain high-temperature oxidation resistance and low-temperature fluidity, and the performance is between synthetic engine oil and mineral engine oil.
Mineral Oil:Mineral oil is a traditional oil refined from petroleum and has a relatively low cost. Mineral engine oil is used in general daily driving conditions and has good lubricating properties, but it is easy to oxidize and degrade in high-temperature environments.
How often should I change it?
Between 5,000 and 10,000 kilometers per year, it is advisable to use fully synthetic motor oil. According to the change interval of fully synthetic engine oil, it is generally recommended to change the engine every 10,000 km or a year to ensure the normal operation of the engine and maintain optimal performance.
If you choose to use semi-synthetic oil, it is recommended to change the oil every 7500 km or a year, depending on its replacement interval, to ensure that the engine is adequately protected and maintained.
And if you use mineral oil, you should change the oil every 5000 km or a year according to its replacement interval to ensure that the engine is running in good working condition.
What does the oil designation represent?
The oil grades used in winter are: 0w, 5w, 10w, 15w, 20w, 25w, the symbol w represents winter, the smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature;
The higher the number, the greater the viscosity and the higher the applicable maximum temperature;
Which oil should I choose?
1.Choose a low-temperature resistant engine oil in extreme environments (such as Jilin and Heihe in winter): In cold climates, it is recommended to choose an oil with good low-temperature performance to ensure that the oil has good fluidity in cold environments and is convenient for starting the engine. Fully synthetic motor oils generally have better low-temperature performance.
2.Choose a high-temperature resistant engine oil in a hot environment (such as Hainan and Turpan in summer): In a high-temperature environment, it is recommended to choose an engine oil with good high-temperature oxidation resistance to ensure the stability and protection of the oil under high-temperature conditions. Fully synthetic motor oils generally have better performance at high temperatures.
3.Turbocharged engines are recommended to choose fully synthetic or semi-synthetic engine oils: Turbocharged engines work in a more demanding environment, requiring oil with good fluidity and high temperature oxidation resistance, so it is recommended to choose fully synthetic or semi-synthetic engine oil.
4.Semi-synthetic or mineral oil is recommended for naturally aspirated engines: Naturally aspirated engines work in a relatively mild environment and have less stringent oil requirements, so semi-synthetic or mineral oil can be chosen.
5.It is recommended to use low-grade engine oil for daily commuting, and it is recommended to choose fully synthetic engine oil for long-distance driving: for daily commuting vehicles, general low-grade engine oil can meet the demand; And for vehicles that often travel long distances, it is advisable to choose a fully synthetic motor oil with better performance and protection.
When choosing a car oil and determining the replacement interval, car owners should consider factors such as vehicle attributes, the environment in which the vehicle is used, the manufacturer's recommendations, and personal preferences. Depending on the type of engine, driving situation and operating environment of the vehicle, it is important to choose the right oil type (e.g. fully synthetic, semi-synthetic or mineral oil) as well as viscosity grade. If you don't care, because you can choose a fully synthetic engine oil, you can save trouble directly.
Choosing the right oil and maintaining it according to the prescribed change intervals can help keep the engine in good condition and improve the performance and reliability of the vehicle, allowing owners to enjoy a safer and smoother driving experience. Therefore, car owners should pay attention to the selection and maintenance of engine oil as one of the important measures to protect the vehicle to ensure the long-term healthy operation of the vehicle.
