Do new cars need break-in additives?
2 Answers
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.
