Engine oil is known as the "blood of the engine", and its quality and adaptability directly affect the lubrication, cooling, and cleaning effects of the engine. Choosing the right engine oil can effectively reduce component wear, delay aging, and is a key factor in extending engine life. Mastering the scientific logic of oil selection is essential for the long-term stable operation of the engine.
1、 Accurately match oil grade to meet engine requirements
The oil grade determines its core performance and should be selected according to the requirements of the vehicle manual. The number before "W" in the label represents low-temperature fluidity, such as 5W and 0W. The smaller the value, the faster the lubrication during low-temperature start-up, making it suitable for high-altitude regions; The number after "W" represents high temperature viscosity, such as 30 or 40. The larger the value, the more stable the oil film at high temperatures, making it suitable for old engines or vehicles that frequently experience heavy loads and high-speed driving. Turbocharged engines require the use of fully synthetic engine oil, which has stronger high-temperature stability and shear resistance, and can meet the lubrication needs of the turbine at high speeds; Natural aspirated engines can choose semi synthetic or fully synthetic engine oils based on operating conditions, balancing performance and cost.
2、 Identify quality standards and reject inferior engine oil
High quality engine oil is the "protective shield" of the engine, and it is necessary to choose products that comply with API (American Petroleum Institute) or ACEA (European Automobile Manufacturers Association) standards. The higher the grade, the more comprehensive the performance. Avoid purchasing low-priced and low-quality engine oil, as its base oil purity is low and the additive ratio is unreasonable, which not only fails to effectively lubricate, but may also produce oil sludge, block the oil circuit, and exacerbate engine wear. It is recommended to purchase through legitimate channels, identify the brand's anti-counterfeiting label, and ensure reliable oil quality.
3、 Adjust according to working conditions and replace regularly without delay
The selection of engine oil should be adapted to the operating conditions. Under frequent short distance driving and congested urban road conditions, the engine is prone to carbon buildup, so it is recommended to choose engine oil with outstanding cleaning performance; Long distance high-speed and high-temperature driving requires emphasis on the high-temperature stability of the engine oil. At the same time, regardless of the quality of the engine oil, it needs to be replaced periodically. It is recommended to replace regular engine oil once every 5000 kilometers or 6 months, while fully synthetic engine oil can be extended to 10000 kilometers or 1 year to avoid the loss of protection after the engine oil ages and deteriorates.
Choosing the right engine oil is not simply about pursuing high prices, but about providing precise protection for the engine by matching the grade, identifying the quality, and adapting to the working conditions. The combination of scientific oil selection and regular replacement is necessary to maximize engine life and reduce operating costs.
