Can New Cars Be Driven on Highways During the Break-in Period?
2 Answers
New cars can be driven on highways during the break-in period, but it is not mandatory. Driving on highways does not necessarily mean running the engine at high RPMs. Modern vehicles are manufactured with high precision and undergo a cold break-in phase before leaving the factory, so their mechanical performance is already in good condition. Therefore, it is acceptable to drive on highways during the break-in period. However, there are a few points to note when driving a new car on highways during the break-in period: 1. Avoid sudden acceleration and hard braking; 2. Monitor the engine oil condition regularly; 3. Use appropriate gear shifts; 4. Ensure fuel quality. Driving a new car on highways during the break-in period is not only fine but may even be better than stop-and-go city driving, which can be less ideal for the break-in process.
As a veteran driver with over a decade of experience, I can confirm that the break-in period for new cars deserves careful attention. While older vehicles required more cautious break-in procedures, modern manufacturing precision has improved, but highway driving is completely fine—the key is to avoid excessive speed or prolonged trips. I always recommend new car owners maintain a speed around 90 km/h on highways, avoid sudden acceleration or hard braking, and keep the engine running smoothly. Internal engine components need time to break in, so keep RPMs below 3,000 at high speeds to prevent increased wear. It's also important to monitor oil and coolant temperatures, ensuring they don't become excessively hot. Drive a few hundred kilometers in city conditions before taking longer highway trips—this helps the car adapt better and ensures more stable future performance. Overall, highways aren't off-limits; just follow the manual's guidelines.
