What are the causes and solutions for Jetta burning engine oil?

[Humbert]

Solution is to replace fuel or components, below are the causes of Jetta burning engine oil: 1. Fuel quality: Due to the difference between domestic fuel quality and international standards, carbon deposits are easily formed in the combustion chamber during engine operation, which are the root cause of various engine problems. 2. Hazards of carbon deposits: Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together. This prevents the piston rings from sealing completely, resulting in reduced compression ratio. The "stuck" piston rings greatly reduce oil scraping ability, leading to increased oil consumption. 3. Component damage: Damage to the oil seal between the turbocharger and intake pipe is mainly caused by excessively long oil change intervals or the use of inferior oil, resulting in insufficient lubrication and cooling for the floating turbo main shaft, which in turn damages the oil seal.
