降低胎压有时甚至会比胎压过高更危险
一些车主在更换润滑油的时候，总是认为越贵的润滑油就越好。这种观点并不正确。其实，在日常使用时，并非要用昂贵的润滑油，而且即使用了好油，济南汽车救援选错了标号也会对车造成伤害。
Some car owners always think that the more expensive lube oil is, the better it will be when changing the lubricating oil. That's not true. In fact, in daily use, not to use expensive lubricants, and that the use of good oil, the wrong selection of labels will also cause harm to the car.
天气热的时候，有老司机建议新手降低胎压来规避爆胎风险。实际上，降低胎压有时甚至会比胎压过高更危险。这是因为，现在的车用轮胎多数是子午线胎。这种胎的胎体，是聚合物多层交叉材质，其顶层是数层由钢丝编成的钢带帘布。
When the weather is hot, the older drivers suggest that novices reduce tire pressure to avoid the risk of tire blowout. In fact, reducing the tire pressure is sometimes more dangerous than the tire pressure is too high. This is because most of the current tyres are radial tires. The carcass of this kind of tire is a polymer multilayer cross ply material, and the top layer is made of several layers of steel cord made of steel wires.
如果胎压不足，这些钢丝变型量就加大，在短时间内会产生大量的热量并可能引发爆胎。同时，胎压过低或过高，都会造成车辆的动力性和制动性能、行驶稳定性下降。胎压过低还会让车更费油。
If the tire pressure is insufficient, the steel wire will increase the amount of change, in a short period of time will produce a lot of heat, and may cause a flat tire. At the same time, the tire pressure is too low or too high, will cause the vehicle dynamic and braking performance, driving stability decline. Tire pressure is too low will make the car more oil.
正确的做法是，在厂商规定的标号范围内选择润滑油。冬天建议大家选择允许范围内黏度相对低的润滑油;反之，夏天则可以选择黏度相对高的润滑油。
The correct way is to choose the lubricant within the label specified by the manufacturer. In winter, it is recommended that you choose the range of relatively low viscosity of lubricating oil; on the contrary, in summer, you can choose a relatively high viscosity of lubricating oil.
很多车主认为发动机舱长期不清洁，难免会落满尘土和油污。因此，在洗车的时候，都喜欢用水枪冲洗发动机舱。其实这样做是错误的，发动机舱是不能用水冲洗的，尤其在发动机尚未冷却时，冷水冲洗发动机舱容易造成汽车内部结构损害。
Many owners believe that the engine compartment is not clean for a long time, it will inevitably be full of dust and oil pollution. So, when you wash the car, you like to wash the engine room with water cannons. In fact, this is a mistake, the engine is not rinse, especially in the engine is not cooling, cold water engine room is easy to cause the automobile internal structure damage.
发动机中有很多电子元件，虽然这些部件已经经过防水处理，但如果使用压力极大的洗车高压枪冲洗，可能会使水渗入发动机以及发动机舱。
There are many electronic components in the engine, although these components have been waterproofed, but if the car high pressure gun using pressure greatly flushing, may allow water to seep into the engine and engine compartment. |
