The effect of engine oil on cars

Lubricating oil is commercial lubricant, lubricating oil has two main components: base oil and additives, in which base oil is the main ingredient accounting for about 75 - 80% of the weight.

The remaining additives, although only a small part, are the decisive factor in the quality of the lubricating oil. These additives have the effect of anti-oxidation, anti-corrosion, anti-mechanical wear and anti-foaming.

The effects of engine oil on cars

Lubrication

Lubrication prevents friction, reduces wear on metal and internal engine parts such as pistons, camshafts, etc. Thanks to the lubrication effect, the piston can move up and down smoothly and quietly in the cylinder. From here, the pump system will spray oil into every corner inside the engine to create a smooth cushion on the contact surface between the parts, increasing operating efficiency and increasing the life of the vehicle engine.

Seal

The oil will act as a cushion to seal the gaps between the piston and the cylinder wall so that the pressure generated during fuel combustion is not lost.

Engine cooling

Cooling ability when the engine is running, when the vehicle is running and the engine is running, the heat emitted from the fuel combustion process is also very large. The engine starts to heat up, the oil will now have a cooling effect, avoiding piston burning.

Clean

Another function of motor oil is to clean the engine. After a long time of operating the vehicle, the fuel combustion process will create a lot of dirt and black soot that sticks to the engine, causing blockage and the engine will quickly heat up.

At this time, the oil will play a role in cleaning the engine, helping the vehicle run smoother and quieter. Depending on the quality of each type of oil, it will have different capabilities, so you need to choose a reputable and quality place to buy. Because poor quality types will not have a cleaning function but also create many impurities and the oil will quickly turn black and degrade.

Anti-rust

Lubricating oil will cover and protect the surface of metal parts inside the engine to limit contact with air, avoiding oxidation that leads to rusting of parts.

From here, the car engine will save more fuel and improve its lifespan and performance later on.

When to change car oil?

Regular oil changes are very important. To know the right time, you need to regularly check with the dipstick, if it is still within the max range, there is no need to change it. In addition, you can also monitor the color of the oil, if the oil is amber, it means that there is no need to change it. Some people have the habit of changing the oil based on the number of kilometers traveled. According to experts, you should change the oil after 5,000 - 10,000km.

Besides, some cases need to change oil sooner such as:

Vehicles operate continuously and must be started frequently.

Even if a car is not used for a long time, the oil should be changed after 1 year, because if left for a long time, the oil will no longer be able to fully function.

The car runs slower or accelerates more slowly than normal.
