What is the recommended speed during the break-in period of a new car?

New cars typically have a break-in period of 1,000 to 3,000 kilometers. The break-in period, also known as the run-in period, has the following key points: 1. Before assembly, each moving part of a car is manufactured separately, and during this process, geometric deviations are inevitable. As a result, some moving parts may have direct localized contact after assembly, making it difficult for lubricating oil to reach the friction surfaces, which can lead to early wear. The break-in period is designed to wear down these direct contact points over a certain period, hence the name. 2. The break-in period for a new car or a major overhauled vehicle generally ranges from 1,000 to 1,500 kilometers. This is the essential mileage required to ensure that components fully contact, friction, adapt, and settle. During this time, the car's components can adjust and enhance their ability to adapt to the environment while wearing down any protrusions on the parts. The quality of the break-in period significantly impacts the car's lifespan, safety, and fuel efficiency.
During the break-in period for a new car, it is recommended to keep the speed between 80 to 100 km/h. When I bought my first car, I followed the manual's instructions—keeping the speed moderate helps the engine break in smoothly and avoids excessive friction between internal components. My friend maintained this speed range during highway driving, and the car later proved to be more fuel-efficient and had a longer lifespan. Driving too fast or accelerating aggressively during this period may cause premature engine wear, increasing future repair costs. The break-in period typically lasts for the first 1,000 kilometers, but checking the manual for specific requirements based on the car model is crucial. During this time, avoid sudden braking or long-distance driving with a full load to give the vehicle more time to adapt. Also, remember to regularly check the engine oil and tire pressure to ensure a smooth transition to normal driving conditions.
I'm more of a technical person and understand that the engine needs a smooth break-in period. It's safer to keep the speed under 100 km/h and the RPM below 3000. When new components start working, gentle driving can reduce friction damage. I personally prefer cruising at around 90 km/h, especially avoiding long-distance high-speed driving to prevent overheating. The break-in period is roughly the first 1,600 kilometers, during which the transmission and braking system also need time to adapt, so maintaining a steady speed is more prudent. Remember to check the owner's manual for specific details, as recommendations may differ between gasoline and diesel models. Simple maintenance and mindful driving habits can significantly extend the engine's lifespan.
From a safety perspective, maintaining a moderate speed during the break-in period is more reassuring. It's recommended to keep the speed around 85 km/h and avoid rushing too fast, allowing the new car to adapt to your control and prevent accidents. Sudden turns or rapid acceleration may lead to loss of vehicle control, especially during the testing phase. In my experience, gentle driving helps the brake system and tires break in better, reducing the risk of sudden malfunctions. The first 1,000 kilometers are the golden period to familiarize yourself with the car, so don't rush to drive at high speeds. Additionally, ensure all lights and dashboard indicators are functioning properly for a smooth journey.
