How to Observe Engine Oil Overfill?

Engine oil level inspection: 1. Ensure the vehicle is parked on level ground to improve the accuracy of oil level measurement. If parked on uneven ground or a slope, move the vehicle to a level surface. 2. Turn off the engine and wait for 5-10 minutes to allow any oil remaining in the upper part of the engine to fully drain into the oil pan. 3. Remove the dipstick and wipe it clean with a lint-free cloth, then reinsert the dipstick into the engine's dipstick tube. Wait a few seconds to allow the oil to fully adhere to the dipstick. 4. Remove the dipstick again and check whether the highest oil mark on the dipstick falls within the specified range.
As a car enthusiast, I frequently check for excessive engine oil. A simple method is to park the car on level ground, turn off the engine, and wait for it to cool completely for about 15 minutes, allowing the oil to fully drain back into the oil pan. Then, pull out the dipstick, wipe off the oil with a clean cloth, reinsert it, and pull it out again to observe. The oil mark should be between the upper and lower limit lines, indicating normal levels; if it's above the upper limit, it indicates excessive oil. During the check, pay attention to any abnormal changes in the oil's color or smell. For example, mixing with gasoline or water can cause the oil to lighten in color, emit unusual odors, or reduce viscosity, increasing the risk of engine wear. Preventive maintenance is crucial. I recommend checking once a month, especially in cold weather when oil dilution is more common, to avoid minor issues leading to major problems. If abnormalities are found, visit a professional repair shop early to prevent serious damage, such as piston ring failure.
As a regular car owner, I've developed the habit of checking the engine oil by starting with the basics: ensuring the car is turned off, parked on level ground, and cooled for at least 20 minutes to allow the oil to settle for accurate readings. After pulling out the dipstick, cleaning it, and reinserting it, I check the oil level. If it exceeds the upper limit mark, it indicates an increase in oil volume, possibly accompanied by a gasoline smell or diluted oil, suggesting fuel mixing issues. Initially, I didn't understand, but now I know this could be due to poor sealing or engine problems. Not addressing it promptly can reduce lubrication effectiveness and accelerate component wear. Making it a habit to check during every maintenance session is much better than panicking after a problem arises and also saves on repair costs.
