Is burning one liter of oil every 2000 kilometers serious?

[VonAlyssa]

Burning one liter of oil every 2000 kilometers is considered a severe oil burning phenomenon. The basic acceptable standard is burning 1.5 liters per 5000 kilometers. Exceeding this standard falls into the category of abnormal combustion. Related information about oil burning: 1. Cause: Engine oil participates in piston lubrication and remains in the piston rings, entering the combustion chamber with the piston's repeated movements and being burned together. 2. Judgment method: A small amount of blue smoke is emitted when the vehicle starts, and the blue smoke disappears after normal driving. 3. Consequences: It shortens the lifespan of the oxygen sensor, clogs the catalytic converter, increases carbon deposits in the combustion chamber, leading to unstable idling, increased fuel consumption, excessive exhaust emissions, and many other issues. If the oil burning problem is not resolved for a long time, insufficient engine oil pressure will cause inadequate engine lubrication, resulting in irreversible excessive engine wear, numerous scratches on the cylinder walls, and damage to piston sealing, ultimately leading to complete engine failure.
