自動(dòng)變速箱維修機(jī)油的選擇依據(jù)?

Selection criteria for automatic transmission maintenance oil

一、車輛使用手冊(cè)?

1、 Vehicle User Manual

車輛使用手冊(cè)是選擇機(jī)油的重要依據(jù)，其中明確標(biāo)注了車輛自動(dòng)變速箱適用的機(jī)油規(guī)格、型號(hào)等信息。按照手冊(cè)要求選擇機(jī)油，能確保機(jī)油與變速箱的兼容性，避免因機(jī)油選擇不當(dāng)導(dǎo)致的故障。例如，某些車型的自動(dòng)變速箱要求使用特定品牌、型號(hào)的全合成油，如果隨意更換為其他類型機(jī)油，可能會(huì)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(dòng)變速箱對(duì)機(jī)油的要求不同。常見的自動(dòng)變速箱類型有 AT（液力自動(dòng)變速箱）、CVT（無級(jí)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(dòng)性的機(jī)油；CVT 變速箱對(duì)機(jī)油的清潔性和摩擦特性要求較高；DCT 變速箱則需要機(jī)油具備出色的抗剪切穩(wěn)定性。在維修時(shí)，要根據(jù)變速箱類型選擇相應(yīng)的專用機(jī)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(fù)荷或頻繁啟停的工況下行駛，對(duì)機(jī)油的性能要求會(huì)更高，應(yīng)選擇耐高溫、抗磨損性能好的全合成油。而對(duì)于行駛工況較為平穩(wěn)、使用頻率較低的車輛，可以適當(dāng)降低機(jī)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(zhì)量?

4、 Brand and Quality

選擇知名品牌和質(zhì)量可靠的機(jī)油是關(guān)鍵。大品牌的機(jī)油在生產(chǎn)工藝、質(zhì)量控制等方面更有保障，能提供穩(wěn)定的性能。同時(shí)，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(jī)油，如授權(quán)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.
