Automotive oil is the blood that maintains the life of the engine. It is a component that can cool and lubricate the engine. Nowadays, more and more car owners realize the importance of regular maintenance and oil change. However, with the development of the urban automobile industry, traffic congestion has become more and more serious. Many office workers will choose public transportation, and the frequency of driving will also decrease. For the maintenance of such vehicles, most people will think that with the decrease in vehicle usage frequency, the maintenance frequency should be reduced accordingly

When the driving frequency is low or the vehicle is parked for a long time, is it necessary to perform regular maintenance and change the engine oil? When the vehicle is used infrequently or parked for a long time, oxidation becomes more severe compared to frequent driving. Once the engine oil oxidizes, its lubricating effect deteriorates, making it unable to provide the original protection to the engine. Additionally, acidic substances in the engine can corrode parts, and oil sludge attached to the engine's lubricating parts can harden and form clumps, seriously affecting the engine's normal operation. Furthermore, the longer the vehicle is stopped, the more severe the deterioration becomes. When the engine is restarted, dry or semi-dry friction forms between the cylinder and piston, accelerating part wear, making it difficult to start the engine, and leading to engine failure. Therefore, for vehicles with low usage frequency or long parking periods, regular maintenance and oil changes are essential to better protect the engine and optimize its performance

However, with the development of the urban automobile industry, traffic congestion has become increasingly severe. Many commuters opt for public transportation, reducing the frequency of driving. Regarding the maintenance of such vehicles, most people believe that as the frequency of use decreases, the number of maintenance checks should also decrease accordingly

1. Lubrication and antifriction

Automotive engine accessories include pistons, cylinders, bearing shells, and main shafts. During movement, frequent and rapid friction occurs between the piston and cylinder, as well as between the main shaft and bearing shell. At this time, it is necessary to establish a sufficiently thick oil film between them to separate the friction surfaces and ultimately reduce friction

2. Reduce corrosion

The oil on the surface of the engine parts of the car will prevent water, air and other harmful substances from coming into contact with the gas

3. Cleaning

Qualified high-quality engine oil can remove oxides, oil sludge, and other metal particles generated on the surface of engine parts through the circulation and flow of engine oil

4. Sealing

Engine oil can form a sealing ring between the piston ring and the piston of engine automotive parts, thereby reducing other leaks and the entry of external gases

5. Cooling

Engine oil can transport the high heat generated by friction and combustion on the contact surface of accessories from the cylinder block to the oil tank, and then release it into the air to cool the engine in the water tank

6. Shock absorption and buffering

When the engine is started, the spark plug ignites the fuel, causing high pressure in the engine cylinder, which puts tremendous pressure on the piston, connecting rod, and crankshaft bearings. Oil plays a significant role in cushioning the load by transmitting it across the surfaces of these stressed automotive components.
