Does driving in S mode all the time damage the engine?

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 will increase directly, becoming an aggressive mode, which is different from the usual gear. Here is some relevant information about S mode: 1. The disadvantages of long-term use of S mode: If S mode is used for a long time, it will accelerate the wear of the originally high-speed rotating parts in the engine due to the more aggressive driving mode of S mode. At the same time, in S mode, the engine speed is increased, and the engine is under high load, at which time fuel consumption will be proportional to the power output. 2. The advantages of S mode: Although S mode has an impact on the engine, it still has some positive aspects. For example, S mode makes the engine inject more fuel to maintain power output during driving. Although this process consumes more fuel, the fuel acts as a cylinder cleaner.
I've been driving for over a decade. The S gear stands for Sport mode, which keeps the engine at higher RPM ranges to deliver stronger power. However, using S gear continuously could potentially harm the engine. High RPM means engine components like pistons and valves operate under constant high load, with significantly increased friction and heat. Over time, this accelerates wear and tear, especially in older vehicles or during frequent high-speed driving, raising the risk of oil burning or mechanical failures. It also leads to a sharp increase in fuel consumption—for instance, using S gear in city traffic might raise average fuel consumption from 8L to 10L per 100km, costing more on fuel. I recommend using S gear only for specific needs like overtaking, climbing hills, or mountain roads, then switching back to D gear (Drive mode) for normal driving to protect the engine, extend its lifespan, and save fuel and money. Although modern cars are designed for durability, proper usage is key to maintenance.
I remember once going on a long road trip with a friend. He drove in Sport mode the whole way, feeling the car was more responsive and exciting to drive. However, a month later, he mentioned his fuel consumption had increased by nearly 20%. Upon inspection, slight engine damage was found, along with abnormal oil consumption. The mechanic attributed it to prolonged high RPM operation causing increased internal wear. I've tried it too—short bursts in Sport mode are fine, but extended use can lead to excessive engine temperatures and faster oil degradation, which isn't worth it. Now I've learned my lesson: I only use Sport mode when necessary and stick to normal mode the rest of the time for smoother and more worry-free driving. Remember, a car isn't a race car—easing off the throttle a bit is better for everyone.
