买了车子回来，不知道选择什么样的机油，全合成、半合成还是矿物？要实惠还是要性能？其实就看用车环境和用车需求！
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就保养，那使用矿物油能省一笔不小的开支；比如家里车开的很少，那显然半合成或全合成更适合；再比如开车凶，天天大脚油门，偶尔再跑个长途，毫无疑问的请使用全合成为发动机提供保护！
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!
无论选择什么油品，一定不要低于原厂要求！不要耍小聪明，把涡轮车的有品标准降低，用个矿物油，是便宜了，花大钱的日子在后面呢！
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!
环境因素不可忽视！
Environmental factors can not be ignored!
1、南方的朋友一定要注意湿气，我们行驶一段距离后，停车、熄火，发动机在经由高温骤然冷却的过程中，空气中的潮气就会凝结成水混入到机油当中。水和机油发生反应，很容易促使机油发生乳化变质，虽然这一过程非常非常的缓慢，可能长达数个月甚更多，但还是会影响到机油的润滑能力，同时也弱化了机油的自身润滑能力。
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、北方的朋友注意寒气，因为在寒冷地区，不管是什么车型，低温启动性能都是为核心的，全合成机油的流动性要大幅好于矿物油，不仅在寒冷地区更容易启动车辆，还可以很大程度的避免因为冷启动润滑不足而造成的发动机磨损！
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.
