Is Break-in Oil Necessary for New Cars During the Break-in Period?
2 Answers
New cars do not require break-in oil during the break-in period, as it has little effect. During the break-in period of a new car, there is no need to add anything. The driver simply needs to operate the vehicle correctly for a proper break-in, use high-quality engine oil products, and pay attention to the maintenance of the oil filter and lubrication system. Below is an introduction to new car break-in additives: 1. New car break-in additives are engine break-in additives, which are lubricating additives with cleaning and dispersing effects. They are used for engines during the break-in period to prevent issues such as cylinder scuffing, bearing seizure, and premature wear. 2. During the break-in period of a new car, it is necessary to quickly bring the various friction surfaces of the engine into good working condition. Generally, high-quality break-in additives are composed of antioxidants, corrosion inhibitors, and some viscosity improvers, which provide certain protection for the engine. In contrast, inferior products are mostly simple anti-wear agents that reduce friction but may prolong the break-in period, which is not conducive to the break-in of a new car.
I've also heard people say that new cars need break-in oil, but with today's advanced manufacturing technology, it's completely unnecessary. The factory-installed oil is specifically designed for the break-in period, containing special additives to help smooth the internal engine components. Adding extra break-in oil might actually interfere with the performance of the original oil and is just a waste of money. What really matters during the break-in period is driving habits—avoid rapid acceleration, high-speed driving, and keep the RPM below 4,000 for the first 2,000 kilometers. The salesperson specifically emphasized when I bought the car: just use the factory oil before the first maintenance and follow the scheduled oil changes at the 4S shop. These practices are far more practical than adding any break-in oil.
