Where is the appropriate oil level for adding engine oil?

[Robles]

For automobile engine oil, the standard level is between the minimum and maximum marks on the dipstick. In vehicles, the dipstick is a commonly used tool to check the amount of lubricating oil in the oil reservoir. Since the dipstick insertion hole has a curved path, the dipstick must be able to deform when inserted and rebound to its original shape when pulled out. Here are some related details: 1. The function of the dipstick: The dipstick measures the static oil level height, indicating whether the engine oil volume is within a reasonable range. Standard dipsticks have clear upper and lower limits. As long as the measured oil level is between these two marks, it is acceptable. 2. More oil is not always better: Ideally, the oil level should be around the middle mark. It is important to note that more oil is not necessarily better. A higher oil level increases engine resistance. The optimal oil level is slightly below the middle mark, as this minimizes engine resistance and fuel consumption while maintaining stable lubrication performance.
