What is the method for checking engine oil level during the three inspections?

There is only one method for checking the engine oil level during the three inspections, which is to ensure that the engine oil level falls between the 2/4 to 4/4 marks on the dipstick. Composition of automotive engine oil: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties. Additives compensate for and improve the deficiencies in the base oil's performance, granting it certain new properties, making them an important component of lubricating oil. Importance of automotive engine oil: The condition of the engine oil not only directly affects the working state of the engine but also influences its lifespan. The working environment of engine oil is extremely harsh, with impurities from gasoline combustion contaminating the oil. Over time, the oil oxidizes and deteriorates.
In my daily car use, I've found that checking the engine oil level is actually quite simple but very important, as it can prevent engine wear. Parking the car on level ground is crucial; otherwise, the reading won't be accurate. After parking, wait a few minutes for the engine to cool down, allowing the oil to settle. Then, pull out the dipstick—many people overlook this step, but it's essential to wipe it clean first with a cloth or tissue to remove any residual oil to avoid misjudgment. Next, fully reinsert the dipstick all the way in, wait a few seconds, then gently pull it out again to observe the oil level mark. The oil trace should ideally be between the min and max marks. If it's below the min line, you'll need to add new oil, but pour it in slowly to avoid overfilling; if it's too high, you'll need to remove some to prevent pressure issues. I recommend checking once a week, especially after long-distance driving, to promptly detect oil leaks or other minor issues. This habit is worry-free and cost-saving, and it can also extend your car's lifespan.
