What is the normal level on the oil dipstick?

[DeJoy]

Generally, oil dipsticks have two marked lines, and the oil level between these two lines during routine vehicle checks is considered normal. Below is more information about oil dipsticks: 1. Purpose: The oil dipstick is not only used to check the level of engine lubricating oil; experienced drivers or mechanics can detect many engine operating conditions by inspecting the oil dipstick, thereby maintaining the engine, identifying the causes of faults or issues in time, and preventing further deterioration of problems. 2. Meaning of the dipstick marks: Standard oil dipsticks typically have clear upper and lower limits. It is sufficient to ensure the measured oil level is between these limits, though the middle position is ideal. Note that more oil is not necessarily better—higher oil levels actually increase engine resistance. Ideally, keeping the oil level slightly below the middle position minimizes engine resistance and fuel consumption while maintaining stable lubrication performance.
