Is Break-In Additive Necessary for the First Maintenance of a New Car?

[JosephLynn]

New cars do not require the addition of break-in additives during their first maintenance, nor do they need any extra additives in future maintenance. While various additives may have some effect, their cost-performance ratio is not high. Break-in additives are specifically designed for the break-in phase of new cars to improve engine break-in quality and ensure optimal engine run-in results. The first maintenance refers to the initial service after a new car has been driven, with the timing varying by vehicle—typically performed after driving 1,000 to 3,000 kilometers. Car maintenance involves regular preventive work such as inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts, also known as car servicing.

I just bought a new car and completed its first maintenance. The 4S dealership recommended adding a break-in additive, but I directly refused because I checked the owner's manual and it didn't mention anything about it. Modern engines are already treated before leaving the factory, so there's no need to spend money on extra additives. The money saved can be used for better engine oil or reserved for minor repairs like tire pressure checks. In fact, the most crucial aspect of new car maintenance is following the manufacturer's guidelines. Over-maintenance can cause more trouble—for example, break-in additives might alter the oil composition and affect lubrication, doing more harm than good. When driving a new car, just take it easy and avoid slamming the accelerator. After a few thousand kilometers, perform regular checks to ensure smooth operation.

I've driven several new cars, and during the first maintenance, the staff always push for break-in additives. I tried it once and found it completely useless, just a waste of a few hundred bucks. New car engines are precision-machined during design, and adding such additives might clog the pipes or disrupt the oil balance. It's better to focus on core maintenance like oil and filter changes. Pay attention to speed and temperature during the initial driving period, avoid prolonged high-speed runs, and natural break-in is more reliable than additives. Save some budget for unexpected minor repairs and enhance the driving experience.

During the first maintenance of the new car, I directly told the technician not to touch the break-in additive. Modern cars don't need that stuff - adding it provides no benefits and might even cause problems. The main purpose of first maintenance is just oil change and system parameter checks. Everything else is unnecessary. Keeping it simple and hassle-free is what matters most - don't overcomplicate maintenance.
