How to read the spiral dipstick on a single-cylinder Changchai Hummer circulating water diesel engine?

If the vehicle is in motion, first park the car, turn off the engine, and wait for about 10 minutes to allow the oil to fully return to the oil pan. Pull out the dipstick, wipe off the original oil traces with a clean cloth, and then reinsert the dipstick all the way to the bottom. After a few seconds, pull out the dipstick again to get an accurate oil level reading. There are upper and lower limit marks at the end of the dipstick. Observe the portion wetted by oil—if it falls between the upper and lower limits, the oil level is correct. If the level is above the upper limit, it indicates too much oil; if below the lower limit, it means insufficient oil and requires appropriate topping up.
