Major is generally performed every 20,000-30,000 kilometers or approximately every 2 years. Additionally, it is advisable to follow the specific maintenance schedule recommended by the vehicle manufacturer for different car brands. Below is a detailed introduction: 1. Maintenance Items: Major maintenance is more comprehensive than minor maintenance. Minor maintenance primarily includes: oil change, air filter replacement, oil filter replacement, and a full vehicle inspection; Major maintenance includes all minor maintenance items plus: fuel filter replacement, coolant replacement, gear oil replacement, hydraulic oil replacement, and power steering fluid replacement. 2. Power Steering Fluid: The full name of power steering fluid is power steering oil, which is a special liquid in the power steering pump. It automatically provides hydraulic assistance during steering, making the steering wheel more flexible and easier to operate.

As a long-time driver, I've found that the frequency of major for new cars typically falls between 15,000 to 30,000 kilometers, depending on the car brand and the recommendations in the owner's manual. When you first buy a new car, a minor maintenance check is usually done at around 5,000 kilometers to inspect the break-in condition, followed by the first major maintenance at approximately 15,000 kilometers. This includes oil changes, air filter replacement, and tire balance checks, which help extend engine life and improve fuel efficiency. If you drive frequently, such as daily highway commutes or carrying heavy loads, it's best to service your car every 15,000 kilometers. Conversely, if your driving is lighter, you can stretch it to 25,000 kilometers. From my experience, neglecting maintenance accelerates part wear and increases repair costs, so I always follow the manual's guidelines to keep my car in top condition.

From my years of driving experience, the standard interval for major of a new car is approximately every 20,000 kilometers. Major maintenance is no small matter—it involves checking the brake system, transmission fluid, and cabin air filter to ensure everything runs smoothly. Some vehicles, such as hybrids or SUVs, may have different recommended intervals in the manual, so it's best to adjust based on road conditions. For example, areas with heavy dust may require earlier maintenance. Regular maintenance can prevent issues like spark plug carbon buildup, saving you significant repair costs. I recommend not delaying too long; at least perform maintenance every two years for the car's longevity and your safety.

As a new car owner, I've found that major is typically scheduled between 10,000 to 20,000 kilometers. My manual recommends the first service at 15,000 kilometers, including oil change and suspension system inspection. Maintaining regular intervals during city driving helps reduce fuel consumption issues. If mileage is low, servicing at least every two years prevents oil degradation. This simple and practical approach maintains vehicle performance.

From a safety perspective, it is recommended to perform a major service for a new car every 20,000 kilometers or within two years. This service checks critical components such as brakes and steering systems to prevent failures that could lead to accidents on the road. Neglecting maintenance increases the risk of tire blowouts or brake failures, especially during rainy or snowy conditions. It is advisable to strictly follow the vehicle's manual to maintain overall reliability.

The interval for major is not fixed. For new vehicles under harsh conditions such as muddy roads or frequent overtaking, maintenance may be required every 15,000 kilometers; under relaxed driving conditions, it can extend up to 30,000 kilometers. The manual usually serves as a reference benchmark, and the optimal interval should be adjusted based on driving habits and environment. Regular inspections can help identify minor issues early for timely resolution, ensuring long-term stability.
