Will Dual-Clutch Gear Shifting Cause Jerking?

[MartinRose]

Dual-clutch gear shifting can indeed cause jerking. Due to the mechanical limitations of dual-clutch transmissions and their shifting logic, jerking may occur when driving at low speeds under specific road conditions. There are two main reasons why a car engine burns oil: First, oil burning when the engine is cold. The symptom is that the engine exhaust pipe emits a lot of blue smoke, but returns to normal after the engine warms up. The possible cause is corrosion and aging of the valve oil seal, leading to poor sealing, which allows oil to leak into the combustion chamber from the valve, resulting in jerking after burning. Second, oil burning when the engine is hot. The symptom is that the exhaust pipe does not emit blue smoke when the engine is cold, but emits heavy blue smoke after the engine warms up. This is usually caused by issues with the piston rings. For example, normal wear and tear over time as the car's mileage increases can gradually enlarge the gap between the piston and the cylinder. When this wear reaches a certain level, cylinder blow-by begins, leading to oil burning.
