At the time of maintenance, the most common sentence we heard was probably "the oil is turbid, and it has to be replaced." But why is the Motor oil turbid and must be replaced?

The Eaton Char-lynn Motor states that Motor oil is used in the Motor. Since it is used in machinery, we can imagine that it should be used to lubricate the machine. A relatively large role of Motor oil is to reduce the friction between the moving parts of the Motor to ensure flexible operation of the Motor. We call this lubrication. In fact, in addition to lubrication, Motor oil has the functions of cleaning, cooling, rust prevention, sealing, oxidation resistance and buffering.

1. Cleaning effect

Cleaning means cleaning the carbon, oil and other stains produced by burning, or dissolving the stain in the oil, or using a grease filter to remove the stain. Motor oil cleans the Motor and removes residual impurities from the filter to protect the metal surface from acid corrosion during combustion. At the same time, the Motor oil can also take away combustion residues (carbon deposits), combustion products of the lubricating oil or oxidation products (low temperature sludge) and quickly settle to the bottom of the oil sump. Therefore, the oil seems to be black and dirty, and it is impossible to judge the quality by the naked eye.

2. Cooling effect

Cooling, as the name suggests, cools the Motor. Motor oil can assist the cooling system (such as water, radiators, pumps, cooling circulation systems, and airflow through the Motor and oil crust) to remove heat from the piston. When the piston is cooled, the gasoline is ejected from the opposite side. Therefore, Motor oil must have good cooling performance and can withstand high temperatures.

3. Anti-rust effect

The anti-rust effect is to prevent rust, just like oiling the sword and other things, the metal parts inside the Motor should also prevent rust. These are attributed to another important feature of the lubricant - waterproof, so that the Motor oil can effectively play the role of Motor rust.

4. Sealing effect

Finally, the sealing function, the sealing function of the Motor oil is to seal the piston and the cylinder of the Motor. This degree of sealing is very important, which can effectively prevent the cylinder string gas, ensure the effective power output of the Motor, and improve the vehicle power. That is, the oil is dropped into the gap between the piston and the cylinder to maintain the cylinder pressure.

5. Antioxidant effect

Motor oil fully protects all parts of the Motor. The high temperature generated by the Motor will accelerate the oxidation of the Motor oil. Therefore, the Motor oil must have excellent oxidation resistance to ensure that the Motor oil maintains normal viscosity during a certain oil change interval, and protects all components of the Motor from working properly.

6. Buffering

The Motor oil can withstand a certain impact load from the bearing transmission, which acts as a buffer to eliminate the impact load between the bearing and other parts of the Motor to a certain extent.

Through these several functions, the oil keeps the Motor in good condition. Therefore, the newer the Motor oil, the better the machine performance will be. The oil can't be changed once and it will be done once and for all, and it must be replaced regularly.
