Ordinary lubricating oil products become thicker at low temperature, the fluidity is weakened, and the time to reach the lubrication parts is longer, which makes the vehicle difficult to start and the wear is increased, which is very unfavorable to the engine. When to change the oil of self feeding mixer and what type of oil to choose? Self feeding mixer reminds you of four points to pay attention to:

1. 盡量選擇冬夏通用的機油，通用機油無論溫度怎么變化，都能保持比較穩(wěn)定的潤滑性能，對發(fā)動機能夠起到較好的保護作用。

1. Try to choose the general engine oil in winter and summer. No matter how the temperature changes, the general engine oil can maintain a relatively stable lubrication performance, which can play a better role in protecting the engine.

2. 要根據(jù)發(fā)動機的要求選擇潤滑油，既不能在要求較低的發(fā)動機適用過于高 級的機油，也不能將低級的機油使用在要求較高的發(fā)動機上，總之，發(fā)動機的機油選擇要恰當(dāng)。

2. Lubricating oil should be selected according to the requirements of the engine. Neither too high-grade engine oil should be applied to the engine with lower requirements, nor low-grade engine oil should be used to the engine with higher requirements. In a word, the engine oil selection should be appropriate.

3. 自上料混凝土攪拌罐車要根據(jù)發(fā)動機的狀況來選擇，如果發(fā)動機是新的或者狀況良好的，要盡可能選用粘度較低的機油，從而保證潤滑油的流動暢通無阻，有效減少啟動時的磨損。

3. The self loading mixer should be selected according to the condition of the engine. If the engine is new or in good condition, the oil with lower viscosity should be selected as far as possible, so as to ensure the smooth flow of lubricating oil and effectively reduce the wear during starting.

4. 如果在高溫季節(jié)或發(fā)動機已經(jīng)磨損到一定程度，就要選用高粘度的機油，這樣才能有利于形成較厚的油膜，維持機油的壓力，并減少機油消耗。

4. If the engine has been worn to a certain extent in the high temperature season, it is necessary to choose high viscosity oil, which is conducive to the formation of a thicker oil film, maintaining the oil pressure and reducing oil consumption.

5. 機油的添加量不能過多，機油添加量并不是越多越好，如果潤滑油過多，就會增加曲軸的轉(zhuǎn)動阻力，降低發(fā)動機的輸出功率，并且哪些過量的機油會竄入燃燒室燃燒，造成車輛燒機油，冒藍(lán)煙，以至于油耗增加。所以在添加機油的時候，一定要略低于機油尺高刻度為宜；此外還要掌握機油的型號、換油的季節(jié)、發(fā)動機的性能等諸多因素。

5. The amount of oil should not be too much. The more the oil is added, the better. If there is too much lubricating oil, it will increase the rotation resistance of the crankshaft and reduce the output power of the engine. What excess oil will rush into the combustion chamber and cause the vehicle to burn oil and emit blue smoke, so that the fuel consumption will increase. Therefore, when adding oil, it should be slightly lower than the oil dipstick height scale; in addition, it is necessary to master the oil model, oil changing season, engine performance and many other factors.
