What is the solution for oil burning in the 2015 Passat?

The solution for oil burning in the 2015 Passat is as follows: Use engine oil that meets specifications: Many car owners never read the vehicle manual and still don't know what quality and viscosity grade of oil their vehicle requires after years of driving, showing great randomness in oil usage. When using engine oil, pay attention to both the quality index and viscosity index. The quality index means choosing SL grade or above whenever possible, while the viscosity index must strictly follow the specifications in the car manual, neither too low nor too high. Avoid high-speed driving: Avoid frequent sudden acceleration and prolonged high-speed driving. When the engine runs at extremely high speeds, it can easily cause the lubricating oil film to break, leading to poor lubrication and dry friction in rotating parts. When this becomes a frequent operation, it will cause abnormal engine wear and result in oil burning.
My 2015 Passat had oil consumption issues, what a headache! As a car enthusiast, I've researched this extensively and found that the EA888 engine in Passats is prone to piston ring carbon buildup or aging valve stem seals, allowing oil to sneak into the combustion chamber. For solutions, it's best to start with simpler approaches: try adding an oil repair additive like Liqui Moly, which can temporarily alleviate carbon deposits; if that doesn't work, I recommend visiting a repair shop to check if the PCV ventilation valve is clogged—replacing this small component is affordable and worry-free. My car required valve seal replacement costing over 3,000 yuan, which completely solved the problem. Daily prevention is crucial: I've developed habits like using full synthetic oil and avoiding frequent sudden acceleration to prolong engine life. Monitoring oil consumption is also vital—if you lose more than half a liter per 1,000 kilometers, it's time to take action.
