Should New Cars Add Gasoline Running-in Additives?
2 Answers
New cars should add gasoline running-in additives, also known as engine running-in additives. These are lubricating additives with cleaning and dispersing effects, designed for engines during the break-in period. They help prevent issues such as cylinder scoring, bearing seizure, and premature wear during the break-in phase. During a new car's running-in period, it's essential to quickly establish proper mating conditions for all friction surfaces in the engine. High-quality running-in additives typically consist of antioxidants, corrosion inhibitors, and viscosity improvers, providing certain protective effects for the engine. In contrast, inferior products often contain simple anti-wear agents that reduce friction but may prolong the break-in period, which is detrimental to proper engine running-in.
As an auto enthusiast who enjoys tinkering with cars, I have to say that adding break-in additives to new cars isn't really necessary. In the past, older engines did require these additives to help components break in properly and prevent excessive wear. But modern vehicles undergo precision tuning at the factory, with engine parts pre-lubricated and covered in high-quality oil. I've studied manuals from several brands like Toyota and Ford, and they all state that normal driving is sufficient without additional additives. During the break-in period, driving habits matter most: gentle throttle application, avoiding sudden acceleration, and trying not to drive at high speeds for the first 1,000 kilometers. Adding break-in additives might provide some psychological comfort, but they don't really make much difference. In fact, if you use a low-quality brand, it could potentially interfere with the factory-fill oil. Save that money—it's better spent on quality oil changes, which will give your car just as long a lifespan.
