How much engine oil consumption is normal for 10,000 kilometers?

For normal engine oil consumption over 10,000 kilometers, it should be less than 10 liters. Below is an introduction to engine oil: 1. Introduction: Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil. 2. Composition: It mainly contains anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. 3. Function: Engine oil is used for lubricating internal combustion engines. Its main functions are to reduce friction and wear of moving parts, remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine. It also neutralizes acids produced from fuel and lubricant oxidation (detergents), improves the sealing of piston rings, and cools the engine by carrying away heat from moving parts.
The normal oil consumption for 10,000 kilometers is generally around 3 to 5 liters, which I think depends on the engine type and usage habits. In my experience, wear on the piston rings in regular household cars can cause oil to enter the combustion chamber and participate in burning, which is a normal phenomenon. Newer cars consume less oil, while older cars or turbocharged engines may have higher consumption. I recommend car owners check the oil dipstick monthly—as long as the oil level is between min and max, it's safe. If consumption exceeds 5 liters, there might be an issue, such as an oil leak or component damage. Regular oil changes can help reduce unnecessary consumption and protect the engine. Neglecting this may accelerate engine aging, leading to high repair costs. Recording the amount of oil added during each refueling helps assess trends and maintain the car's long-term health.
In daily driving, I find oil consumption quite common. My eight-year-old sedan consumes about 4 liters of oil after running 10,000 kilometers, and the mechanic said it's within the normal range. This is because internal friction during engine operation consumes a small amount of oil. I make it a habit to check the dipstick every three fuel refills to avoid the oil level getting too low. Factors that influence oil consumption include frequent high-speed driving or traffic congestion, which can accelerate consumption; if blue smoke is seen from the exhaust pipe, it indicates severe oil burning. Using oil with the appropriate viscosity and avoiding overloading can help stabilize consumption. Remember to perform timely maintenance, otherwise it may lead to more serious faults.
