How to Check the Production Date of Great Wall Engine Oil?
1 Answers
The production date of Great Wall engine oil is located at the bottom of the oil container, with the first six digits representing the production date. Automotive lubricants are categorized into mineral lubricants, synthetic lubricants, semi-synthetic lubricants, and others. The functions of automotive engine oil are as follows: 1. Lubrication and wear reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby achieving the purpose of reducing wear. 2. Cooling and temperature reduction: Engine oil can carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine. 3. Cleaning and purification: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of parts via the flow of the lubricating oil. 4. Sealing and leak prevention: Engine oil can form a sealing ring between the piston rings and piston, reducing gas leakage and preventing external contaminants from entering.
