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

[DiMelanie]

Consuming 1L of engine oil per 10,000 kilometers is normal. Below are relevant explanations about oil consumption: 1. Piston operation: Engine oil lubricates pistons, piston rings, and cylinders. When the engine pistons operate, there is an oil film on the cylinder walls, part of which is burned off by the high-temperature combustion gases during the combustion of the air-fuel mixture. 2. High-temperature exhaust: The intake valve stem also requires lubrication by engine oil, which can be drawn into the combustion chamber. High-temperature exhaust gases similarly consume the oil used to lubricate the exhaust valves. 3. High-temperature oxidation: As the engine runs for extended periods, water vapor generated from the high-temperature oxidation of engine oil is drawn into the combustion chamber through the crankcase ventilation valve and burned.
