What is the method for checking the lubricating oil level?

The method for checking the lubricating oil level is: pull out the oil dipstick, wipe it clean with a clean cloth, reinsert it, and then pull it out again to check the oil level. The functions of automotive lubricating oil are: 1. Lubrication: prevents excessive wear between the piston and cylinder; 2. Cleaning: the oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and by the flow of the lubricating oil, it washes away dirt generated on the working surfaces of the parts; 3. Sealing and leak prevention: the oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering.
I've been checking the oil level myself every time I change the oil, a habit I've maintained for over ten years. First, find a level ground to park the car, wait about ten minutes after turning off the engine to let the oil settle. Open the hood, locate the dipstick with the yellow or orange ring, and gently pull it out. Remember, always wipe the dipstick clean with a cloth before reinserting it all the way, then pull it out again to check the oil mark. The normal oil level should be between the upper and lower marks on the dipstick. If it's too close to the lower mark, add some oil immediately, but exceeding the upper mark can increase engine load. Checking once a month is sufficient, especially before long trips. By the way, checking when the engine is cold gives the most accurate reading, as hot oil may not have fully settled and could lead to misjudgment.
