Do new cars need break-in additives?

New cars do need break-in additives. Here is some information about break-in additives: 1. Break-in Additives: New car break-in additives are lubricating additives with ultra-strong cleaning and dispersing effects. They provide exceptional protection for engines during the break-in period, preventing common issues such as "cylinder scoring," "bearing seizure," and early wear that are prone to occur during this phase. 2. Functions: They can improve the surface roughness of metal components, thereby promoting thorough component break-in. During vehicle operation, they also enhance lubrication and reduce noise generation. The cleaning function is the most important role.

I also wondered whether to add break-in additives when I first bought my new car. Looking back, it was unnecessary. Modern engine manufacturing technology has advanced significantly, with thorough testing and break-in preparations done at the factory. Adding break-in additives only aims to reduce engine wear, but the factory-installed oil already provides sufficient protection. These additives might even contaminate the oil or prove ineffective, wasting money. More importantly, drive gently for the first 500 kilometers or so: avoid rapid acceleration at high speeds and don't haul heavy loads. What really matters is following the manufacturer's manual for regular maintenance and using the correct oil type. In short, saving this money for better fuel or adding an anti-theft film is more practical.

As a car enthusiast who often tinkers with vehicles, I can confidently say that adding break-in additives to a new car is completely unnecessary. Modern engine components are manufactured with precision processes and wear-resistant materials, and the break-in process is simulated before the car even leaves the factory. While break-in additives claim to shorten the break-in period, they may actually interfere with the performance of the engine oil and even cause subsequent issues due to additive residue. The key lies in driving habits: keep the RPMs in check for the first 1,000 kilometers and avoid frequent hard braking. I've seen cases where adding break-in additives actually increased engine noise—it's better to stick faithfully to the maintenance schedule. New cars aren't relics; excessive pampering is less practical than using them scientifically.

Honestly, there's no need to worry about adding break-in additives for new cars. I've heard from mechanics that modern engines are designed so advanced that natural driving during the break-in period is sufficient. Instead of spending those few dozen dollars on break-in additives, it's more practical to change the oil one more time or add car mats. Just drive a bit slower in the first few hundred kilometers and avoid racing—everything will be fine. Follow the maintenance manual during servicing, it's more worry-free, effortless, and much safer.
