Myth 1: the higher the viscosity of engine oil, the better

一般來說，從潤滑的角度來說粘度過大，自上料攪拌車啟動時機油就上的慢，而車輛啟動和機油沒有完全熱起來的時候對車輛的磨損是的，機油的作用之一是給發動機散熱冷卻。我們知道發動機冷卻液主要負責發動機上部燃燒室周圍零部件的冷卻。

Generally speaking, from the point of view of lubrication, the viscosity is too high, and the oil starts slowly when the loading mixer starts. However, when the vehicle starts and the oil is not fully heated up, the wear of the vehicle is the biggest. One of the functions of the oil is to cool the engine. We know that the engine coolant is mainly responsible for cooling the parts around the upper combustion chamber of the engine.

除此之外的各個運動部件都要依靠機油來散熱。如果粘度過大，單位時間內機油的流量小，則零部件的冷卻效果就會差很多。相應的，零部件冷卻不好，其使用壽命就會大打折扣。因此，機油選擇合適的粘度才是對發動機的保護。

In addition, all moving parts rely on oil to dissipate heat. If the viscosity is too high and the oil flow per unit time is small, the cooling effect of parts will be much worse. Accordingly, the service life of the parts will be greatly reduced if the parts are not cooled well. Therefore, the oil to choose the appropriate viscosity is the greatest protection for the engine.

誤區二：合成機油比礦物油粘度稀

Myth 2: synthetic oil viscosity is thinner than mineral oil

很多的人憑外觀感覺會認為相同粘度等級合成機油粘度太稀機油壓力會不好，實際上合成機油特性就在于此。因此發動機對于機油的粘度要求是低溫啟動和低溫運轉必須保證粘度足夠低，才能減少磨損。自上料攪拌車發動機高溫運轉必須保證合適的粘度，才能保證足夠的潤滑效果。機油有個評價指標：粘度指數，粘度越高指數越高，說明機油的穩定性越好，全合成機油粘度指數可以達到160以上，而普通礦物機油粘度指數一般不會超過100.所以合成機油的優勢只有在發動機高溫和環境低溫情況下才能展現出來。

Many people will think that the same viscosity grade synthetic oil viscosity is too thin, oil pressure will be bad, in fact, this is the characteristics of synthetic oil. Therefore, the engine oil viscosity requirements are low temperature start and low temperature operation, the viscosity must be low enough to reduce wear. The proper viscosity must be ensured for the high temperature operation of the self loading mixer engine to ensure the sufficient lubrication effect. There is an evaluation index of engine oil: viscosity index. The higher the viscosity, the higher the index, which indicates the better stability of the oil. The viscosity index of fully synthetic oil can reach more than 160, while the viscosity index of ordinary mineral oil generally does not exceed 100. Therefore, the advantages of synthetic oil can only be shown under high engine temperature and low ambient temperature.

自上料攪拌車發動機選擇什么粘度等級的機油，是由發動機溫度和發動機個零部件配合間隙以及零部件剪切強度決定的。

What viscosity grade oil is selected from the engine of charging mixer is determined by engine temperature, fit clearance of engine parts and shear strength of parts.
