公里数没到时间到了要换油吗？
济南自动变速箱维修人员认为，公里数没到时间到了要换变速箱油。为什么这么讲？下面来看看吧。
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.
变速箱油是否需要换了要看两个条件，一个是公里数，另一个是时间。两个条件以先到达的为准。严格来说，公里数和时间，两个条件只要有一个条件达到了，就要去换变速箱油了。因为变速箱油也是有保质期的。
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.
变速箱油开封以后，加到汽车变速箱里的这个过程，是掺杂了空气的到达一定的时间以后，变速箱油里的物质就会发生氧化反应，变速箱油就不能有效地保护汽车的变速箱了。
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.
不过现实当中也要根据实际情况灵活分析。时间是可以稍微延迟的，只要延迟的时间不是很久，就没有问题。
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.
举个例子:全合成变速箱油，正常情况下是4-6万公里或2年更换一次。如果到了2年的时候，车辆才行驶了3万公里，这种情况下就不用立刻去更换变速箱油。延迟一两个月再更换也没事。但是如果延迟了一年多才换，那问题就大了。在延迟的这段期间，由于变速箱油无法有效的保护变速箱，变速箱的磨损会非常严重，会大大的缩短变速箱的寿命。
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.
市场上，可供车主们选择的变速箱油品牌有很多，换油的时候也不要图便宜，尽量选择品牌和质量较好的变速箱油进行更换，并选择在正规渠道购买与车辆相符的油品型号。
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.jnbsx.com , learn more about maintenance matters!
