To what level on the dipstick should engine oil generally be filled?

Engine oil should generally be filled between the upper and lower marks on the dipstick, ideally near the middle position. Method for checking engine oil level: Most dipsticks have clearly marked upper and lower limit indicators. When used correctly, the dipstick helps determine whether the engine has sufficient and appropriate oil levels. Proper usage is essential when checking the oil level. For instance, the engine should be turned off and left undisturbed for 15 minutes before checking, or you can check it in the morning before driving, as the static oil level is most accurate at these times. When checking the dipstick, ensure all tires are on level ground and the vehicle is not tilted, as this could lead to inaccurate measurements.
When maintaining my car, I always make sure to add engine oil between the upper and lower marks on the dipstick, that is, between the min and max lines. The correct procedure is to park the car and turn off the engine, wait for about five minutes to let the oil settle, then pull out the dipstick, wipe it completely clean, reinsert it, and check if the oil level is in the middle zone. Why is this so important? Because if the oil level is below the min line, there's too little oil for proper lubrication, leading to rapid wear of engine components or even overheating damage; if it's above the max line, the oil pressure becomes too high, potentially damaging valves or oil seals and causing blue smoke, which wastes oil. I usually check it every 5,000 kilometers, and when adding oil, I use a funnel to pour in new oil slowly, being careful not to overfill, checking multiple times to prevent overflow. These details were learned from experienced drivers, and sticking to them can save a lot on repair costs and provide peace of mind while driving.
