Normal oil consumption is 2 liters per 10,000 kilometers. 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 engine cylinder ports; 5. To flush away dirt generated on the working surfaces of components. The method for changing engine oil is: 1. Lift the vehicle, remove the protective plate, and place a container of about 10 liters under the oil drain plug; 2. Loosen the oil drain plug, use an air gun to blow into the oil filler port for two minutes, tighten the drain plug after draining, and wipe it with a tissue to check for oil leaks; 3. Reinstall the protective plate, lower the vehicle, and use a funnel to add oil through the filler port.

Normal oil consumption refers to the process where a small amount of oil is consumed during engine operation, which is quite common in driving. After years of driving, I've found that consuming 0.1 to 0.5 liters of oil per 1,000 kilometers is within the normal range, depending on the car model, age, and driving habits. For example, new cars or those using full synthetic oil may consume less, while older cars or frequent high-speed driving may lead to higher consumption. I make it a habit to check the dipstick every 1,000 kilometers. Park the car on level ground, and when the engine is cold, pull out the dipstick to check the oil level. If the oil level is in the middle of the scale, there's no need to worry. However, if it's below the minimum mark or consumption exceeds 0.8 liters per 1,000 kilometers, it might indicate issues like piston ring problems or seal leaks, requiring prompt repair to avoid engine seizure or major overhauls. Additionally, using high-quality oil and changing it on schedule can help reduce consumption and extend the car's lifespan.

Monitoring oil consumption can prevent major issues. I consider a consumption of 0.1 to 0.5 liters per 1,000 kilometers to be a reasonable benchmark. This is primarily caused by internal engine wear, oil evaporation, or minor burning in the combustion chamber. Older vehicles or those under heavy loads may consume slightly more, but don't overlook the risk of oil leaks. In my own car maintenance routine, I prioritize regular checks, typically measuring oil levels with the dipstick when the engine is cold. If consumption increases noticeably—for example, if oil levels drop significantly in a short time—it could indicate piston ring issues or aging seals. I recommend using synthetic oil with the appropriate viscosity, as it's more stable and evaporates less. Avoid sudden acceleration and prolonged idling during normal driving to reduce unnecessary oil consumption. Address any abnormalities early to avoid costly engine repairs.

Oil consumption is a normal phenomenon, with 0.1-0.5 liters per 1,000 kilometers being acceptable. Influencing factors include engine type and maintenance condition: new cars or those with less oil consumption experience minimal loss, while older or high-revving cars consume more. Checking the dipstick is crucial, and I make it a habit to inspect it every time I refuel. If consumption is rapid, such as losing oil every 500 kilometers, promptly check for leaks or internal issues. High-quality oil reduces this risk.
