What is the normal amount of engine oil?
3 Answers
Engine oil is considered normal when its level is between the upper and lower limits. The functions of engine oil are: 1. To alleviate friction and high temperatures; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases, and engine components; 4. To buffer the pressure rise in the engine cylinder port; 5. To flush away dirt generated on the working surfaces of components. Signs that indicate the need for an oil change include: 1. Checking the oil viscosity—if there is no viscosity, the oil needs to be changed; 2. The oil color turns black; 3. Excessive black particles, metal shavings, or carbon deposits in the oil; 4. The oil smells unusual. The steps for changing engine oil are: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the drain plug; 2. Unscrew the drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the drain plug after draining and wipe it with a tissue to check for leaks; 3. Reinstall the undercover, lower the car, and use a funnel to add new oil into the filler port.
I've been driving for a while and noticed that the normal oil level is usually between the minimum and maximum marks on the dipstick. When checking, make sure the engine is cool, pull out the dipstick, wipe it clean, reinsert it, and then pull it out again to see the oil line. If the oil line is right in the middle, that's ideal. If it's below the minimum mark, increased engine friction can lead to wear and even cause oil burning. If it's above the maximum mark, the oil can overflow and foam, damaging seals or increasing pressure. I make it a habit to do a quick check once a month after parking overnight to catch any issues early. Also, when adding oil, don't rush to pour in too much—stick to the manufacturer's recommended amount. Regular oil changes are crucial too, typically every 5,000 kilometers, to ensure engine longevity.
How much engine oil is normal? The dipstick will tell you. Check the oil level when the engine is cold – as long as it's between the minimum and maximum marks, you're safe. Too little oil may cause component damage, while too much can lead to oil emulsification or overflow. When topping up, never overfill – add gradually for safety. While oil viscosity also matters, don't worry about that yet – focus on quantity first. Personally, I make it a habit to check every two weeks, especially before long trips – this routine has saved me from major repairs.
