Is it necessary to add break-in additives when refueling a new car?

It is not necessary to add break-in additives when refueling a new car. The key for a new car is the break-in period, during which the metal components of the engine need to make contact, break in, and become familiar with each other. It is crucial to quickly bring the engine's friction surfaces into good working condition, drive the car correctly for proper vehicle break-in, use high-quality engine oil products, and pay attention to the maintenance of the oil filter and lubrication system. Generally, high-quality break-in additives are composed of antioxidants, corrosion inhibitors, and some viscosity improvers, which provide certain protection for the engine, and adding them will not have any adverse effects. Most inferior products are simply anti-wear agents, and reducing friction may prolong the break-in period, which is not conducive to the break-in of a new car.
As someone who frequently studies automotive technology, I believe adding break-in additives when fueling a new car is basically unnecessary. Modern car engines undergo precision machining and testing before leaving the factory, with advanced materials and processes. For example, my car has never used them and has been running perfectly fine for years. Manufacturers typically account for the break-in period during the design phase, so additional additives might actually create unnecessary burdens, such as contaminating the fuel system or affecting sensors. The focus during the break-in period should be on driving habits, like avoiding sudden acceleration or high-speed driving, allowing components to naturally adapt. In short, saving this money is more cost-effective—it’s more practical to spend it on regular maintenance.
