How to Check the Production Date of Great Wall Engine Oil?
2 Answers
The production date of Great Wall engine oil is located at the bottom of the oil container, with the first six digits indicating the production date. Automotive lubricating oils are categorized into mineral lubricating oils, synthetic lubricating oils, semi-synthetic lubricating oils, and others. Under normal storage conditions—sealed at room temperature, protected from dust, water, and chemical fumes—Great Wall brand lubricating oils have a shelf life of approximately three years. The functions and roles of engine oil: Engine oil is used for lubricating internal combustion engines. Its primary functions include reducing friction and wear on moving parts, removing sludge and varnish from the engine, neutralizing acids produced by fuel combustion and lubricant oxidation, improving piston ring sealing, and cooling the engine by dissipating heat from moving components.
I usually maintain my car by myself, and it's quite simple to check the production date when using Great Wall motor oil. There's often a laser-engraved date code on the top of the bottle cap, in a four-digit format. The first two digits represent the last two digits of the year, for example, 23 stands for 2023, and the last two digits indicate the week number, such as 01 meaning the first week. Combined, 2301 means early 2023. Motor oil typically has a shelf life of about 2 to 5 years. Beyond that, it oxidizes and its lubricating ability decreases, potentially accelerating engine wear. I always check before changing the oil, as fresher products are more reliable. Storage is also crucial: keep it in a cool, dry place, and avoid leaving it open for too long, otherwise, it may deteriorate and affect performance. Developing this habit saves money and ensures safety—killing two birds with one stone. Other tips include checking if there's a label on the side of the can, making the whole process simple and efficient.
