買了車子回來，不知道選擇什么樣的機油，全合成、半合成還是礦物？要實惠還是要性能？其實就看用車環境和用車需求！
When I bought the car, I didn't know what kind of oil to choose. Total synthetic, semi-synthetic or mineral? Do you want affordability or performance? Actually, it depends on the environment and the demand of using the car!
比如城市代步，5000公里就保養，那使用礦物油能省一筆不小的開支；比如家里車開的很少，那顯然半合成或全合成更適合；再比如開車兇，天天大腳油門，偶爾再跑個長途，毫無疑問的請使用全合成為發動機提供保護！
For example, if you use mineral oil to maintain 5,000 kilometers in a city, you can save a lot of money; if you drive very few cars at home, it is obviously more suitable for semi-synthetic or full-synthetic; and if you drive fiercely, you can run long distances every day, no doubt, please use full-synthetic to provide protection for the engine!
無論選擇什么油品，一定不要低于原廠要求！不要耍小聰明，把渦輪車的有品標準降低，用個礦物油，是便宜了，花大錢的日子在后面呢！
No matter what kind of oil is chosen, it must not be lower than the original requirements! Don't play smart, reduce the quality standards of turbines, use mineral oil, it's cheap, spend a lot of money in the future!
環境因素不可忽視！
Environmental factors can not be ignored!
1、南方的朋友一定要注意濕氣，我們行駛一段距離后，停車、熄火，發動機在經由高溫驟然冷卻的過程中，空氣中的潮氣就會凝結成水混入到機油當中。水和機油發生反應，很容易促使機油發生乳化變質，雖然這一過程非常非常的緩慢，可能長達數個月甚至更多，但還是會影響到機油的潤滑能力，同時也弱化了機油的自身潤滑能力。
1. Friends in the South must pay attention to humidity. After we drive a long distance, we stop and stop. During the sudden cooling of the engine through high temperature, the moisture in the air will condense into water and mix into the oil. The reaction between water and oil can easily lead to the emulsification and deterioration of oil. Although this process is very slow and may last for several months or more, it still affects the lubrication ability of oil and weakens the self-lubrication ability of oil.
2、北方的朋友注意寒氣，因為在寒冷地區，不管是什么車型，低溫啟動性能都是為核心的，全合成機油的流動性要大幅好于礦物油，不僅在寒冷地區更容易啟動車輛，還可以很大程度的避免因為冷啟動潤滑不足而造成的發動機磨損！
2. Friends in the North pay attention to the cold weather, because in cold areas, no matter what type of car, the low-temperature starting performance is the core. The fluidity of synthetic oil is much better than that of mineral oil. It is not only easier to start vehicles in cold areas, but also to avoid engine wear and tear caused by insufficient cold-start lubrication to a large extent.
