As the Frost Descent solar term arrives, the temperature difference between day and night increases, and your car’s engine requires extra attention. The engine is the heart of the vehicle, and inside it, numerous metal surfaces are in constant frictional motion. These components move at high speeds in a harsh environment, with operating temperatures ranging from 400°C to 600°C.

　　With the arrival of the Frost Descent solar term, the temperature difference between day and night is increasing. Your car’s engine also requires extra attention. The engine is the heart of the vehicle, and inside it there are numerous metal surfaces that rub against each other during operation. These components move at high speeds in a harsh environment, with operating temperatures ranging from 400°C to 600°C. Under such severe operating conditions, only qualified lubricating oils can reduce wear on engine parts and extend their service life. So, what requirements must a qualified lubricating oil meet?

1. Lubrication and friction reduction
　　Between the piston and the cylinder, as well as between the crankshaft and the bearing shells, there is rapid relative sliding. To prevent premature wear of these parts, it is necessary to establish an oil film between the two sliding surfaces. An oil film of sufficient thickness will separate the surfaces of the sliding parts, thereby reducing wear.
2. Cooling and temperature reduction
　　The engine oil can carry heat back to the oil pan and then dissipate it into the air, helping the radiator cool the engine.

3. Cleaning and sanitation
　　Good-quality motor oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil pan via circulation. As the lubricant flows, it washes away contaminants that have accumulated on the surfaces of moving parts.
4. Sealed and leak-proof
　　Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering.

5. Rust and corrosion prevention
　　Lubricating oil can adhere to the surface of parts, preventing water, air, acidic substances, and harmful gases from coming into contact with the parts.
6. Shock absorption and cushioning
　　When the pressure at the engine cylinder port rises sharply, the load on the piston, piston rings, connecting rod, and crankshaft bearings suddenly increases dramatically. This load is transmitted through the bearings and lubricated, thereby cushioning the impact load.
　　Currently, there are many counterfeit products on the market that are being sold under false pretenses. Vehicle owners must carefully distinguish between genuine and fake products. It’s recommended to purchase or have your oil changed at designated dealerships, from well-known brands, or at reputable repair shops.
