How to Check the Production Date of Great Wall Motor Oil?
2 Answers
Great Wall Motor Oil production date can be checked by looking at the production batch number printed at the bottom of the oil can. The first six digits represent the production date. Motor oil is composed of base oil and additives. The base oil is the main component of motor oil, determining its basic properties, while the additives compensate for and improve the shortcomings of the base oil's performance, making them an important part of motor oil. The functions of motor oil are: 1. To alleviate friction and high temperatures; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases, and parts; 4. To buffer the pressure rise in the engine cylinder port; 5. To wash away dirt generated on the working surfaces of parts.
As an average car owner, I often buy Great Wall motor oil, and checking the production date is my habit. Generally, there's a small label on the bottle or canister—look for the words 'Production Date' or 'Batch Number.' The batch number is usually a six-digit code, like 230101 representing January 1, 2023, which is straightforward to understand. Motor oil typically has a shelf life of 2-5 years, so checking the date helps avoid buying expired products, which could compromise lubrication and harm the engine. When purchasing oil, I recommend inspecting the label right in the store—don’t just focus on price. Fresh oil ensures smoother engine performance. Also, remember to store it in a cool place to extend its shelf life.
