What is the normal amount of engine oil?

[LaJosiah]

Engine oil level is normal when it is between the upper and lower marks on the dipstick. The functions of engine oil are: 1. To reduce wear between the piston and cylinder, as well as between the main shaft and bearing bush, providing lubrication; 2. To assist in cooling the engine internally; 3. To clean carbon deposits, sludge, and metal particle impurities from engine components; 4. To minimize gas leakage and prevent external contaminants from entering; 5. To cushion and absorb shocks on the piston, piston rings, connecting rod, and crankshaft bearings. The method to check the remaining oil level is: 1. Park the vehicle on level ground, turn off the engine, and wait for fifteen minutes to allow the oil to drain back into the oil pan; 2. Remove the dipstick, wipe it clean, then slowly reinsert it, ensuring it reaches the bottom of the oil pan; 3. Remove the dipstick again and check the oil level.

I've driven quite a few cars and know that maintaining the correct oil level is crucial. Typically, after parking the car and letting the engine cool for a while, pull out the dipstick, wipe it clean, reinsert it, then pull it out again to check the level—the oil should be between the Min and Max marks on the dipstick. If it's too low, the engine won't be properly lubricated, leading to overheating and wear; if it's too high, excessive pressure can cause leaks or smoke. I check it every 5,000 kilometers or so, keeping it slightly above the middle for optimal performance. When topping up, always use the same type of oil—never mix different grades to avoid emulsification. Full synthetic oil can extend maintenance intervals, with slightly thicker viscosity in summer and thinner in winter, as recommended in the vehicle manual. Regular checks can add years to your car's life, saving both money and hassle.

When I first started learning to drive, I was always worried about engine oil issues. My instructor taught me that the normal level should be between the Min and Max marks on the dipstick, and checking it when the engine is cold gives the most accurate reading. If it's below Min, you need to add some oil of the same brand promptly; if it's too high, you should drain some to avoid malfunctions. Once, I forgot to check, and the car made a hissing sound—later I learned it was due to too little oil damaging the engine. Now I’ve developed the habit of checking it monthly: park on level ground, wait a few minutes, then pull out the dipstick to check. When the oil level is normal, the car runs smoothly with low fuel consumption; otherwise, it can lead to oil burning or even breakdowns, which would be a huge hassle. Regular maintenance, like timely oil changes, helps extend the car’s lifespan.

Maintaining the proper oil level is simple—just ensure the dipstick reading falls between the marks when the engine is cold. Too little oil causes dry friction in the engine, resulting in loud noise and higher fuel consumption; excessive oil leads to white smoke and component damage. I recommend checking it monthly or every few thousand kilometers. When topping up, use the same type of oil and avoid overfilling. Proper maintenance ensures quieter engine operation, better performance, and even some fuel savings. Regular oil changes are crucial—select the viscosity matching the season as per your owner's manual.
