要放干凈攪拌機機油的原因是啥?發動機工作時，機油會受到各種金屬的高溫燃燒和催化作用，并逐漸老化，產生積炭、油泥等對發動機有害的物質。它們在發動機的不同部位產生，積聚在油路中，會加速磨損，導致潤滑不良，影響發動機的使用壽命。

What is the reason to drain the mixer oil? When the engine is working, the engine oil will be subject to high-temperature combustion and catalysis of various metals, and will gradually age, producing carbon deposits, sludge and other substances harmful to the engine. They are produced in different parts of the engine and accumulate in the oil circuit, which will accelerate wear, cause poor lubrication and affect the service life of the engine.

所以說要掌握正確的換油周期及相關知識，作為車主，不僅要學會選擇正確的機油，還要掌握一些自動混凝土攪拌機的換油周期及相關知識。

Therefore, we should master the correct oil change cycle and related knowledge. As a car owner, we should not only learn to choose the correct oil, but also master some oil change cycles and related knowledge of automatic concrete mixer.

如果說發動機是汽車的心臟，那么機油就是汽車的血液。起到潤滑、清洗、冷卻、防腐、防銹、密封等作用。發動機內有大量的金屬表面相互摩擦，因此需要潤滑油來減少磨損，而金屬摩擦產生的碎屑也會聚集和釋放，這是造成機油發黑的主要原因。

If the engine is the heart of the car, then the oil is the blood of the car. It has the functions of lubrication, cleaning, cooling, corrosion prevention, rust prevention, sealing, etc. A large number of metal surfaces in the engine rub against each other, so lubricating oil is needed to reduce wear, and the debris generated by metal friction will also accumulate and release, which is the main reason for the blackening of engine oil.

在維護過程中，應排空機油15分鐘以上。通常，我們出去保養的時候，不注意排油多長時間。為了追求效率，有的店放油5-6分鐘，導致油渣，對車的影響很大。建議您在保養時提出“機油排放15分鐘以上”的要求。新車尤其重要。車主一定要注意。

During maintenance, drain the engine oil for more than 15 minutes. Usually, when we go out for maintenance, we don't pay attention to how long it takes to drain the oil. In order to pursue efficiency, some stores drain oil for 5-6 minutes, resulting in oil residue, which has a great impact on the car. It is recommended that you put forward the requirement of "oil drainage for more than 15 minutes" during maintenance. New cars are particularly important. Car owners must pay attention.

新手學習如何更換發動機機油：

Beginners learn how to change engine oil:

選擇合適的機油而不是貴的機油。

Choose the right oil instead of expensive oil.

換油前，好開車出去走走，讓機油均勻潤滑發動機，并將發動機內部沉淀的雜質帶出來。

Before changing the oil, drive out for a walk, let the engine oil lubricate the engine evenly, and bring out the impurities precipitated inside the engine.

打開發動機底部的放油口，開始放油。放完機油后，務必排空發動機15分鐘，以便將發動機中的殘余機油完全排空。

Open the oil drain at the bottom of the engine and start to drain the oil. After draining the oil, be sure to drain the engine for 15 minutes in order to completely drain the residual oil in the engine.

仔細觀察流出的機油。如果油非常粘稠、分層且有輕微氣味，則應縮短換油周期。如果有強烈的汽油味，說明發動機燃燒室密封性不好。好找師傅修一下。

Carefully observe the oil flowing out. If the oil is very viscous, stratified and has a slight smell, shorten the oil change interval. If there is a strong smell of gasoline, the engine combustion chamber is not well sealed. I can find a master to repair it.

關閉油口螺栓并更換新的機油濾清器。

Close the oil port bolt and replace with a new oil filter.

打開機油加注口，注入新的發動機機油，檢查油尺的上限。

Open the oil filler, fill in new engine oil, and check the upper limit of the dipstick.

加油后，啟動發動機，啟動汽車，怠速幾分鐘后關閉發動機。再次檢查油尺，看是否需要補充機油。更多關于攪拌機換油的事項您可以關注網站http://www.gdfcx.net看看！

After refueling, start the engine, start the car, and turn off the engine after idling for a few minutes. Check the dipstick again to see if it is necessary to replenish oil. For more information about the oil change of the mixer, you can follow the website http://www.gdfcx.net have a look!
