How to see if the dipstick is correct?

There are upper and lower limits on the dipstick. When the car's oil quantity is between the upper limit and the lower limit, it means that the oil quantity is normal and can be used continuously. When the oil level exceeds the upper limit of the dipstick, it is easy to increase carbon deposition; When the oil level reaches the lower limit of the oil level gauge, it will cause the phenomenon of engine cylinder missing, which will affect the service life of automobile engine for a long time.
