How Often Should the First Major Maintenance Be Performed on a New Car?

[VanBriella]

Major maintenance is typically performed every 30,000 to 40,000 kilometers. Major maintenance refers to the routine replacement of engine oil, oil filter, air filter, and fuel filter within the time or mileage specified by the manufacturer. Details about major maintenance are as follows: Introduction to Major Maintenance: Major maintenance is a comprehensive service that includes not only routine items but also inspections or replacements of previously unaddressed components. Generally, it is recommended to perform major maintenance every 50,000 kilometers. Basic items include: Replacement of engine oil, oil filter, air filter, cabin air filter, and spark plugs; inspection of brake pads, brake fluid, and tires; additionally, checking for carbon buildup in the throttle body and engine cylinders. During operation, the engine generates various frictions, and the resulting debris mixes with the engine oil. If the oil is not filtered regularly, it will directly affect the lubrication performance of the engine.

I think the first major maintenance for a new car should generally be done at around 10,000 to 15,000 kilometers or after one year. I remember when I first started driving, I accidentally delayed it until 20,000 kilometers before getting it checked, and the engine oil was all sticky—my engine almost gave out. Now I go on time every time. For example, changing the engine oil is the top priority because metal debris can come out during the new car's break-in period, and if not cleaned promptly, wear and tear accelerates. You also need to check critical parts like brake pads and tire pressure, especially if you frequently drive on mountain roads or in heavy traffic—then major maintenance should be done earlier. I’ve also developed a habit of checking the oil level every two months myself; catching small issues early saves money and hassle.

Don't rush to hit the road after getting a new car. The first major maintenance is crucial, usually at 1 year or 15,000 km. The manual clearly states different requirements for different cars - I remember Volkswagen recommends first service at 10,000 km. Treat the manual as your bible, don't just follow friends' advice. Driving habits matter too - avoiding hard acceleration and sudden braking can delay maintenance needs. Make it a habit to check warning lights on the dashboard after parking. Safety comes first - this money is well spent.

From a technical perspective, the first major maintenance for a new car is recommended at 10-15k kilometers or after one year. The core task is changing the engine oil and oil filter, as initial part break-in during the early stages of a new car generates debris. Failing to replace the oil accelerates its degradation, reducing engine efficiency and increasing fuel consumption. Additionally, the air filter should be inspected, as excessive dust accumulation can impair combustion quality. Owners shouldn't solely rely on 4S shops; learning basic checks like coolant level and battery condition monitoring can prevent unexpected failures and extend vehicle lifespan.

As parents who take care of kids at home, the first major maintenance of a new car must be closely monitored—safety comes first. Generally, you should visit the repair shop once a year or every 13,000 kilometers, focusing on checking the braking and lighting systems to avoid any mishaps when taking the kids out. Especially in areas with heavy snowfall in winter, check the antifreeze to prevent pipes from freezing and cracking in cold weather. I additionally recommend an air conditioning system check to ensure clean and fresh air inside the car. Keeping the car well-maintained saves hassle, reduces repair costs, and provides peace of mind when taking the whole family out for fun.

If you care about the environment, the first major maintenance for a new car should be done promptly at 1 year or 12,000-15,000 kilometers. Timely maintenance ensures more efficient engine operation, and changing to new oil reduces harmful emissions, making a significant contribution to the environment. Remember to check tire wear and the brake system for efficient driving with less smoke. Electric vehicles are more special; the first maintenance should focus on battery care and the use of recycled parts. Good maintenance extends the car's lifespan, reduces waste, saves money, and protects the planet.
