Is the New Car Break-in Period Underpowered?

[Shaun]

During the new car break-in period, it's not that the car lacks power, but rather that the engine's output hasn't yet reached its optimal performance. In the break-in phase, there are minor surface irregularities on engine components, resulting in relatively higher resistance, which improves after the break-in. Correct methods for breaking in the engine during this period: 1. Every 50km, check the transmission, front and rear drive axles, wheel hubs, and drive shafts for any unusual noises or overheating; 2. Inspect the braking system's effectiveness, tightness, and sealing; 3. For the first 0 to 500 kilometers of driving, keep the engine speed below half of its maximum and the vehicle load below half of its maximum capacity.

When I first bought my new car, I really felt the lack of power during the first few hundred kilometers. Pressing the accelerator didn't give much response, and acceleration was a bit slow. Later, after checking information and asking friends, I learned that the engine needs time to adapt during the break-in period. The piston rings, cylinder walls, and other components of a new engine haven't fully seated yet, and the lubricating oil hasn't evenly distributed, so the power output might be slightly reduced—this is not a malfunction. Modern cars are well-designed with short break-in periods, usually becoming normal after driving about 1,000 kilometers. If you feel a lack of power, avoid stomping on the accelerator or running at high RPMs for extended periods on highways, as this could harm the engine's lifespan. Regularly check the engine oil to ensure proper lubrication, and you'll smoothly transition through this phase. In short, don't worry—it'll regain its vitality as you keep driving.
