What is the proper oil level after parking the car overnight?

[CarlosMarie]

Normally, as long as the oil level is between the upper and lower marks on the dipstick, it is acceptable. After parking the car overnight: Checking the oil level after the car has been parked overnight is very accurate because the engine is in a cold state, and all the oil has flowed back into the oil pan. Typically, after turning off the engine for 10-15 minutes, the oil will fully return to the oil pan, and you can directly pull out the dipstick to check the level. Below the minimum mark: When you first pull out the dipstick, you cannot immediately check the oil level because there is often oil residue on the dipstick. You need to wipe it clean with a tissue, reinsert it, and then pull it out a second time to accurately read the oil level. If the oil level is below the minimum mark, even though there may still be some oil left in the pan, you should promptly visit a 4S dealership or add oil yourself as soon as possible.
