Is it necessary to clean debris after the break-in period of a new car?

[JosephRose]

New car engine iron debris needs to be cleaned, for the following specific reasons: 1. Affects vehicle performance: If the iron debris generated during the break-in period is not promptly removed, it can damage the piston rings, leading to reduced sealing performance in the future, ultimately resulting in power loss and affecting vehicle performance. 2. Causes mechanical damage: Iron debris circulating with the engine oil over time can wear down various connecting parts inside the engine. The engine operates at high speeds, with tight clearances between the piston and cylinder walls, connecting rod bearings and crankshaft, etc. If these parts are frequently rubbed by iron debris, the heat generated in a short time can be enough to melt the metal, causing mechanical damage or even seizure.
