How do I check the oil on top of my car?

Hold a piece of gauze in one hand, and with the other hand, pull out the dipstick 2 to observe the scale. The gauze is wrapped inside the dipstick when you pull it out. After pulling out the dipstick, wipe the dipstick from top to bottom, then insert the dipstick into the engine. Pull out the dipstick and check that the oil should be between two scales to confirm that the oil level is normal.3 Insert the dipstick back into the engine after checking If the oil is insufficient, add it to the normal scale and insert the dipstick back into the engine after checking.
