What is the best speed to drive during the break-in period of a new car?

For a car in the break-in period, it is essential to control the driving speed and avoid excessively high speeds. The speed should preferably be maintained between 50~80 km/h. Here is some information about the car break-in period: 1. The break-in period generally refers to the process where mechanical components initially come into contact, rub against each other, and mesh during operation. 2. The car break-in period refers to the initial phase after purchasing a new car or completing a major overhaul, typically covering 1000~1500 kilometers. This mileage is fundamental to ensure that the components fully contact, rub, adapt, and settle. During this period, the ability of various car parts to adapt to the environment can be adjusted and improved, and the protrusions on the components can be worn down. The quality of the car's break-in will significantly impact its lifespan, safety, and fuel efficiency.
For the break-in period of a new car, I've always believed it's best to keep it under 70 miles per hour. I remember when I bought my first car, the salesperson said the first 1,500 miles are crucial—it's when the internal engine components gradually wear in. Never push it to high speeds, or the piston rings and cylinder walls will wear out too quickly. I recommend driving at moderate speeds in mixed city and highway conditions, avoiding prolonged constant speeds. With 20 years of driving experience, I've seen many new drivers immediately hitting 80 mph, only to end up with noisier engines and higher fuel consumption. While new car technology has improved, playing it safe never hurts. Regularly check oil pressure and temperature, and changing the oil after break-in will help the car last longer, saving you from costly major repairs. In short, drive gently and prioritize safety.
From a maintenance perspective, it's best to keep a new car's break-in period within the range of 65 to 70 miles per hour. The engine has microscopic rough surfaces that require low-speed operation to smooth out friction. Excessive speed can cause RPMs to spike, leading to overheating and permanent damage. I recommend checking the owner's manual for specific guidelines - generally, avoid rapid acceleration and full loads during the first 1,000 miles. Vary your driving routes weekly, such as slow city driving on weekdays and light highway practice on weekends. This ensures even break-in of engine components, extending lifespan by 15%. Don't forget to check tire pressure and oil levels to ensure everything is normal. Taking it easy during break-in benefits the vehicle and prevents costly repairs later.
