How to Check the Production Date of Engine Oil?

Engine oil production dates are indicated on small packaging or the box. For large barrel packaging, the production time and date are printed on the white cap pressed on top. Below is relevant information about engine oil: 1. Characteristics: Advanced technology converts natural gas into crystal-clean fully synthetic base oil, to which unique power cleaning technology is added, creating lubricants with superior cleaning and protective performance. 2. Viscosity Value: 10W-40 represents its SAE standard viscosity value. This viscosity value first indicates that the oil is multi-grade. W stands for WINTER, and the number before W represents the oil's flow performance at low temperatures—the smaller the number, the better the starting performance in cold conditions. The number after W indicates the oil's stability at high temperatures (i.e., its tendency to thin out)—the larger the number, the better the high-temperature stability performance.

When performing routine car maintenance, I often check the production date of engine oil. It's actually quite simple to find - there's usually a string of numbers or letters printed on the outer packaging of the oil container, typically located in a corner of the label or at the bottom of the bottle. The common format is YYMMDD style numbers, for example 240315 indicates production on March 15, 2024. Some brands use batch codes like ABC24-03 to represent March 2024 production. I recommend scanning this immediately when purchasing new oil to avoid buying products that have been in stock too long or are nearing expiration, since engine oil generally has a shelf life of 1-2 years - expired oil loses lubricity and accelerates engine wear. Storage conditions also affect date validity, so avoid exposure to sunlight and humid environments. Developing this habit takes less than half a minute but saves considerable hassle. From my personal experience, checking the date before each oil change results in smoother acceleration and helps avoid unnecessary repair expenses.

As a car owner, I care a lot about saving money, so checking the production date of engine oil is a basic skill. The production date is usually located on the label of the oil container, which may be a small line of numbers or a code. Identifying it ensures the use of fresh oil and avoids wasting money on products nearing expiration. Aged oil is prone to oxidation and deterioration, leading to poor lubrication, and prolonged use can cause expensive engine repairs. In the past, I bought discounted oil without checking the date, and after using expired oil, my car shook badly—I regretted not checking. Now, every time I pick up oil in the store, I carefully look for the date section, such as the first two digits indicating the year for easy calculation. Developing this habit protects my car and saves money—a win-win situation.

I haven't been driving for long, but learning to read the production date of engine oil keeps me on track. There's usually a small label on the engine oil bottle packaging, with numbers like 24-05-20 indicating it was produced on May 20, 2024. Don't worry about not understanding it—most designs are clear, and the location isn't hard to find. If you can't find it, just ask the store clerk or check the manual for clarification. I was confused at first, but now every time I get new oil, I first check the date to make sure it's fresh and not expired. Using old oil can damage the engine and affect driving safety. This little trick is easy to pick up and quickly became a habit for me.
