How many kilometers can a new car run on the highway?

Generally, you can take the car for a high-speed run only after the first maintenance. Below is some information about running the car at high speeds: Reasons for running at high speeds after the first maintenance: Before the first maintenance, the engine oil is the first batch, which contains the most metal shavings and impurities. Using this oil with a large amount of debris for high-speed runs will significantly increase engine wear and may even cause abnormal wear. As a result, the vehicle after the break-in period may not be in the best condition. Precautions: Drive at low speed with high engine RPM, keeping the engine above 3000 RPM before shifting gears. For automatic transmission cars, you can switch to "manual mode" or use low gears to adjust.

When I first bought my new car, the manual said not to drive too fast for the first 1,000 kilometers, mainly breaking it in around the city. By the time I hit 1,500 kilometers, I felt the engine was much smoother, so I took a 200-kilometer short trip on the highway. I maintained a steady speed of around 100 km/h, avoiding sudden acceleration or braking, which helps the piston rings break in and clear carbon deposits. An experienced driver told me that modern cars have shorter break-in periods, but running them at high speeds too early carries risks—if internal parts wear out, repairs can be extremely expensive. To be safe, I always carry a bottle of water and stop at service stations to check the tires and oil temperature.

Don't rush to hit the highway with your new car! Manufacturers generally recommend driving about 1,500 kilometers before pushing it on high speeds. For example, like me, I only drove to and from work during the first month, waiting until the engine runs smoothly before speeding up. Maintaining a steady speed of 80-100 km/h on the highway is ideal. Pushing it too early without proper break-in may lead to higher fuel consumption. A friend once took a long trip after only 500 kilometers, resulting in engine noise and a 5,000 yuan repair bill. Don't forget to check tire pressure and coolant, and warming up the engine before driving is common sense.

I've been driving for over 20 years, and it's best to wait until after 1500 kilometers before taking a new car on the highway. For the first thousand kilometers, drive in the city to break in the components, avoiding high RPMs. After that, maintain a steady speed of around 90 km/h on the highway to help clean engine deposits and improve performance. Don't believe in immediately pushing the car to high speeds—it causes excessive wear and shortens the lifespan. Safety is the top priority; stopping on the highway due to a malfunction is dangerous.

Save money on car maintenance starts with the break-in period. From my experience, it's more cost-effective to take your new car on the highway only after driving around 1,600 kilometers. Driving too early consumes more fuel and harms the engine. Waiting until the break-in is complete and then driving at a constant speed on the highway actually saves fuel. For example, driving 100 kilometers on the highway can save you a few dollars in fuel costs and also extend the engine's lifespan. Check the manual to ensure you don't exceed the manufacturer's recommendations.

Engine internal components require gentle operation for the first 1,500 kilometers for break-in. I always recommend maintaining a steady high-speed cruise after completing the mileage, keeping below 100 km/h to avoid high RPM damage. This helps piston rings achieve better sealing and reduces subsequent oil consumption issues. Before driving, ensure proper tire pressure and normal coolant temperature.
