公里數沒到時間到了要換油嗎？
濟南自動變速箱維修人員認為，公里數沒到時間到了要換變速箱油。為什么這么講？下面來看看吧。
The mileage is not up. Is it time to change the oil? Jinan automatic transmission maintenance personnel believe that it is not time to change the transmission oil before the mileage is up. Why do you say that? Let's take a look.
變速箱油是否需要換了要看兩個條件，一個是公里數，另一個是時間。兩個條件以先到達的為準。嚴格來說，公里數和時間，兩個條件只要有一個條件達到了，就要去換變速箱油了。因為變速箱油也是有保質期的。
Whether the transmission oil needs to be changed depends on two conditions, one is the mileage, and the other is the time. The two conditions are based on the first one to arrive. Strictly speaking, as long as one of the two conditions, mileage and time, is met, it is necessary to change the transmission oil. Because transmission oil also has a shelf life.
變速箱油開封以后，加到汽車變速箱里的這個過程，是摻雜了空氣的到達一定的時間以后，變速箱油里的物質就會發生氧化反應，變速箱油就不能有效地保護汽車的變速箱了。
After the gearbox oil is unsealed, the process of adding it to the vehicle gearbox is that after the mixture of air reaches a certain time, the substances in the gearbox oil will undergo an oxidation reaction, and the gearbox oil cannot effectively protect the vehicle gearbox.
不過現實當中也要根據實際情況靈活分析。時間是可以稍微延遲的，只要延遲的時間不是很久，就沒有問題。
However, in reality, it is also necessary to analyze flexibly according to the actual situation. Time can be slightly delayed, as long as the delay time is not long, there is no problem.
舉個例子:全合成變速箱油，正常情況下是4-6萬公里或2年更換一次。如果到了2年的時候，車輛才行駛了3萬公里，這種情況下就不用立刻去更換變速箱油。延遲一兩個月再更換也沒事。但是如果延遲了一年多才換，那問題就大了。在延遲的這段期間，由于變速箱油無法有效的保護變速箱，變速箱的磨損會非常嚴重，會大大的縮短變速箱的壽命。
For example, fully synthetic transmission oil is normally replaced every 40000 to 60000 kilometers or every two years. If the vehicle has only driven 30000 kilometers in two years, there is no need to change the transmission oil immediately. It's okay to delay the replacement for a month or two. However, if the replacement is delayed for more than a year, the problem becomes greater. During this period of delay, due to the inability of transmission oil to effectively protect the transmission, transmission wear can be very severe, greatly shortening the life of the transmission.
市場上，可供車主們選擇的變速箱油品牌有很多，換油的時候也不要圖便宜，盡量選擇品牌和質量較好的變速箱油進行更換，并選擇在正規渠道購買與車輛相符的油品型號。
In the market, there are many transmission oil brands available for car owners to choose from. When changing oil, do not try to be cheap. Try to choose a better brand and quality transmission oil for replacement, and choose to purchase oil models that match the vehicle through regular channels.
When replacing the transmission oil, try to choose a qualified repair shop for replacement, to avoid improper oil replacement operations that may damage the vehicle and money! Follow us http://www.ihudie.cn , learn more about maintenance matters!
