Does Driving in S Mode All the Time Damage the Engine?

[SanSamuel]

Driving in S mode all the time can damage the engine. S mode is a sport mode, and when switched to S mode, the car's power increases directly, turning into an aggressive driving mode, which is different from the usual gear settings. Long-term use of S mode can accelerate the wear of high-speed rotating components inside the engine due to the more aggressive driving style in S mode. At the same time, the engine speed is increased in S mode, putting the engine under high load, and fuel consumption will be proportional to the power output. Although S mode has an impact on the engine, it also has positive aspects. For example, S mode makes the engine inject more fuel to maintain power output while driving. This process consumes more fuel, but the fuel acts as a cylinder cleaner. When excessive fuel is injected into the cylinder, it can clean the carbon deposits on the valves and inside the cylinder, making the power output smoother. Occasionally using S mode can still be beneficial to the engine to some extent.
