自動變速箱維修機油的選擇依據(jù)?

Selection criteria for automatic transmission maintenance oil

一、車輛使用手冊?

1、 Vehicle User Manual

車輛使用手冊是選擇機油的重要依據(jù)，其中明確標注了車輛自動變速箱適用的機油規(guī)格、型號等信息。按照手冊要求選擇機油，能確保機油與變速箱的兼容性，避免因機油選擇不當導致的故障。例如，某些車型的自動變速箱要求使用特定品牌、型號的全合成油，如果隨意更換為其他類型機油，可能會影響變速箱的正常工作。?

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、變速箱類型?

2、 Transmission type

不同類型的自動變速箱對機油的要求不同。常見的自動變速箱類型有 AT（液力自動變速箱）、CVT（無級變速箱）、DCT（雙離合變速箱）等。AT 變速箱通常需要具有良好抗磨性和低溫流動性的機油；CVT 變速箱對機油的清潔性和摩擦特性要求較高；DCT 變速箱則需要機油具備出色的抗剪切穩(wěn)定性。在維修時，要根據(jù)變速箱類型選擇相應的專用機油。?

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、車輛使用條件?

3、 Vehicle usage conditions

如果車輛經(jīng)常在高溫、高負荷或頻繁啟停的工況下行駛，對機油的性能要求會更高，應選擇耐高溫、抗磨損性能好的全合成油。而對于行駛工況較為平穩(wěn)、使用頻率較低的車輛，可以適當降低機油的性能要求，但也要確保滿足變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、品牌與質量?

4、 Brand and Quality

選擇知名品牌和質量可靠的機油是關鍵。大品牌的機油在生產(chǎn)工藝、質量控制等方面更有保障，能提供穩(wěn)定的性能。同時，要注意避免購買假冒偽劣產(chǎn)品，建議通過正規(guī)渠道購買機油，如授權經(jīng)銷商、品牌官方網(wǎng)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.
