自动变速箱维修机油的选择依据​

Selection criteria for automatic transmission maintenance oil

一、车辆使用手册​

1、 Vehicle User Manual

车辆使用手册是选择机油的重要依据，其中明确标注了车辆自动变速箱适用的机油规格、型号等信息。按照手册要求选择机油，能确保机油与变速箱的兼容性，避免因机油选择不当导致的故障。例如，某些车型的自动变速箱要求使用特定品牌、型号的全合成油，如果随意更换为其他类型机油，可能会影响变速箱的正常工作。​

The vehicle manual is an important basis for selecting engine oil, which clearly indicates the oil specifications, models, and other information applicable to the automatic transmission of the vehicle. Choosing the oil according to the manual requirements can ensure compatibility between the oil and the gearbox, and avoid malfunctions caused by improper oil selection. For example, some models of automatic transmissions require the use of specific brands and models of fully synthetic oil. If the oil is changed to other types at will, it may affect the normal operation of the transmission. ​

二、变速箱类型​

2、 Transmission type

不同类型的自动变速箱对机油的要求不同。常见的自动变速箱类型有 AT（液力自动变速箱）、CVT（无级变速箱）、DCT（双离合变速箱）等。AT 变速箱通常需要具有良好抗磨性和低温流动性的机油；CVT 变速箱对机油的清洁性和摩擦特性要求较高；DCT 变速箱则需要机油具备出色的抗剪切稳定性。在维修时，要根据变速箱类型选择相应的专用机油。​

Different types of automatic transmissions have different requirements for engine oil. Common types of automatic transmissions include AT (hydraulic automatic transmission), CVT (continuously variable transmission), DCT (dual clutch transmission), etc. AT transmissions typically require oil with good wear resistance and low-temperature fluidity; The CVT gearbox has high requirements for the cleanliness and friction characteristics of the engine oil; The DCT gearbox requires oil with excellent shear stability. When repairing, it is necessary to choose the corresponding specialized oil according to the type of gearbox. ​

三、车辆使用条件​

3、 Vehicle usage conditions

如果车辆经常在高温、高负荷或频繁启停的工况下行驶，对机油的性能要求会更高，应选择耐高温、抗磨损性能好的全合成油。而对于行驶工况较为平稳、使用频率较低的车辆，可以适当降低机油的性能要求，但也要确保满足变速箱的基本使用需求。​

If the vehicle is frequently driven under high temperature, high load, or frequent start stop conditions, the performance requirements for the engine oil will be higher, and fully synthetic oil with good high temperature resistance and wear resistance should be selected. For vehicles with smoother driving conditions and lower frequency of use, the performance requirements of the engine oil can be appropriately reduced, but it is also necessary to ensure that the basic usage needs of the gearbox are met. ​

四、品牌与质量​

4、 Brand and Quality

选择知名品牌和质量可靠的机油是关键。大品牌的机油在生产工艺、质量控制等方面更有保障，能提供稳定的性能。同时，要注意避免购买假冒伪劣产品，建议通过正规渠道购买机油，如授权经销商、品牌官方网店等。

Choosing well-known brands and reliable quality engine oil is key. Big brand engine oil has more guarantees in production technology, quality control, and can provide stable performance. At the same time, it is important to avoid purchasing counterfeit and inferior products. It is recommended to purchase engine oil through legitimate channels such as authorized dealers and official brand online stores.
