What are the symptoms of engine oil burning in a car?

It can cause the oxygen sensor to fail prematurely, leading to adverse effects such as increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, and excessive exhaust emissions. Below is a detailed introduction: Cold-start oil burning: Park the vehicle overnight and observe the exhaust emissions during the first start in the morning. If the exhaust emits thick blue smoke, it indicates the vehicle is experiencing oil burning. If the blue smoke disappears after the engine warms up, this type of oil burning is classified as cold-start oil burning. Continuous oil burning: If blue smoke is visible immediately upon starting, the engine's oil burning condition is already quite severe and may even pose a safety hazard. Acceleration-induced oil burning: After the engine is warmed up, whether during rapid acceleration or idling, if blue smoke is emitted from the exhaust pipe whenever the RPM rises sharply, it indicates the vehicle is experiencing oil burning.
