How much engine oil is considered normal for a car?

For a car, the engine oil level should reach the max mark on the dipstick to be considered normal. Engine oils are categorized into mineral oil, semi-synthetic oil, and full synthetic oil. Their functions include: 1. Reducing friction and high temperatures; 2. Minimizing gas leakage and preventing contamination from external pollutants; 3. Protecting parts from contact with water, air, and harmful acidic gases; 4. Buffering the pressure rise in the engine cylinder ports; 5. Cleaning dirt generated on the surfaces of components. When checking the oil level, ensure the vehicle is parked and the engine is turned off. The car should be on level ground, and the oil level should be checked three to five minutes after turning off the engine. If the oil level is significantly below the max mark, it should be promptly topped up.
When I first started driving, I was always confused about how much engine oil should be in the car. Now I understand, and checking it is quite simple. Every time I'm in line at the gas station, I park the car, turn off the engine, and wait a few minutes for the oil to settle. Then I pull out the dipstick, wipe it clean with a cloth, reinsert it, and slowly pull it out to check the level—the ideal position is in the middle area between the min and max marks. Generally, if the oil stain is between the two lines, it's normal. I make it a habit to check once a week, especially before long highway trips, because if the oil level is too low, the engine will wear out faster, and if it's too high, it might leak and cause exhaust odor. Remember to do this on a flat surface; don't measure on a slope, or the reading will be inaccurate. If you find the level below min, add a bit of oil to top it up—don't delay. This can save you a lot on repair costs and extend the engine's lifespan.
