For the first 500 kilometers, avoid heavy loads and keep the speed below 80 km/h. Within the first 1,000 kilometers, slight loads are acceptable, but the speed should not exceed 100 km/h. For the first 2,000 kilometers, the speed should not exceed 120 km/h. Here are some precautions for driving a new car on the highway: 1. Maintain a reasonable speed: A reasonable speed does not mean driving at a constant speed like cruise control, but avoiding both low-speed driving and high-RPM sudden acceleration. The speed should ideally be kept below 100 km/h, and pay attention to the engine RPM and speedometer during driving, ensuring the engine RPM does not exceed 3,000. 2. Avoid flooring the accelerator when starting or slamming on the brakes: Emergency braking can shock the braking system and increase the impact load on the chassis and engine. 3. Use gears appropriately for manual transmission cars: Avoid prolonged low-gear driving, and neither high-gear low-speed nor low-gear high-speed driving is optimal. For automatic transmission cars, relying solely on "D mode" is not recommended; using modes like S or manual mode appropriately is beneficial for the transmission. 4. Avoid full loads and especially overloading: This can cause damage to mechanical components. Additionally, if the new car is used in northern winters, it is best to allow the engine sufficient time to lubricate before starting.

Just got a new car and running on the highway, I always advise beginners to keep the speed between 80 to 90 kilometers per hour. This speed helps protect the engine, allowing it to break in gradually and avoid premature wear on components. At high speeds, wind resistance increases, putting more load on the engine, which can lead to noise or higher fuel consumption. Safety first—when I drive, I maintain a steady speed, and the brakes and new tires are more responsive, preventing skidding. During the break-in period of a few hundred kilometers, it's best not to exceed 100 km/h. Wait until the car runs smoothly before accelerating. Regularly check tire pressure and fluid levels, and don't rush into long-distance trips.

When I first took my new car on the highway, I tried various speeds and found that between 90 to 100 km/h was the most suitable. Keeping the RPM not too high reduces engine load and improves fuel efficiency. New cars need to be treated 'gently'—sudden acceleration or racing can damage components. Highway conditions are complex, so maintaining a steady speed reduces vibrations and enhances seat comfort. During the break-in period, keep an eye on the dashboard; as long as the temperature is normal, you're good. After driving a few thousand kilometers and getting a better feel for the car, you can gradually increase the speed. Don't push the speed limit right from the start.

New car engines have a break-in period, and it's best to maintain a speed between 70 to 90 km/h on highways. This speed keeps the RPM stable, around under 2000 RPM, ensuring even wear of components and extending their lifespan. Exceeding 100 km/h increases the load, leading to a surge in fuel consumption and a higher risk of carbon buildup. Checking tire pressure is essential during high-speed driving, and the new car's suspension system also needs time to adapt. For safe driving, maintaining a constant speed is better than frequent acceleration and deceleration, as it allows for quicker brake response. After the break-in period, the vehicle's performance becomes smoother.

Safe driving is a priority for new car owners. My advice is not to exceed 100 km/h on highways. The suspension and engine of a new car are still stiff, making it harder to control at high speeds, especially in rain or on curves. Maintaining a speed between 80 and 90 km/h is safer, more fuel-efficient, and reduces vibrations. It's recommended to drive at a steady speed to avoid sudden acceleration and brake wear. During the break-in period, conduct regular checks. After the car has run about a thousand kilometers and adapted, you can gradually increase the speed. Avoid rushing and speeding.

I think the appropriate speed for a new car on the highway is within the range of 80 to 100 kilometers. During the break-in period, the engine needs to be taken care of, and maintaining a steady speed on the highway reduces the load, extending the car's lifespan. Driving at excessively high speeds, such as 120 km/h, can cause the RPM to soar, easily leading to oil burning or clutch damage. In terms of safe driving, maintaining a steady speed reduces the risk of accidents, especially since new tires have strong grip and are more reliable. Before the first maintenance, pay extra attention to oil temperature and unusual noises. After a few months of driving, the car will run smoothly, so don't rush to test its limits.

How Many Kilometers Should Thor Engine Oil Be Replaced?

Repsol Thor engine oil typically lasts for 3,000-3,500 kilometers. Markings: The viscosity grade containing "W" indicates all-season applicability. The number preceding "W" denotes the minimum operating temperature – a lower number signifies better low-temperature fluidity and suitability for colder climates. Numbers: The digit following "W" represents the oil's kinematic viscosity at 100°C. Higher values indicate greater viscosity and superior high-temperature stability. For older vehicles with reduced engine performance, lower-viscosity lubricants may be preferable. Always consult professionals when selecting engine oil specifications.
