How Often Should You Change the Oil in a New Car?

New cars should have their oil changed approximately every three months. Engine oil is the lifeblood of a car, serving functions such as lubrication, sealing, rust prevention, cushioning, and cleaning. Engine oils are primarily categorized into three types: mineral oil, semi-synthetic oil, and fully synthetic oil. Commonly used oils include mineral oil and semi-synthetic oil, which typically have a lifespan of around 5,000 kilometers or six months, hence the recommendation for minor maintenance every 5,000 kilometers. Fully synthetic oil has a longer lifespan, usually around 10,000 kilometers, and is often used in mid-to-high-end vehicles. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent, determining the fundamental properties of the oil, while additives compensate for and enhance the performance shortcomings of the base oil, providing certain new properties, making them a crucial part of engine oil.
I just went through this! The first maintenance for a new car is crucial. Usually, the 4S shop requires it to be done at 5,000 km or within 6 months (whichever comes first), mainly to remove debris generated during the engine break-in period. My Japanese car manual states 8,000 km for the first maintenance, but the 4S shop guy specifically advised me to come in at 5,000 km. Avoid aggressive driving during the break-in period—my friend took his new car on mountain roads in the first month, and the oil drained during the first maintenance was as black as ink. Turbo cars with particulate filters need timely oil changes even more; repairs for clogs can be painful. Remember, the maintenance manual is the most accurate guide—requirements vary significantly by brand.
Actually, it depends on two things: the manual's specifications and the type of oil you use. Mineral oil usually needs to be changed every 5,000 kilometers—my cousin's entry-level commuter car uses this. Semi-synthetic can last up to 7,500 kilometers, and many domestic cars come with this from the factory. Full synthetic is the most hassle-free; my German car with Mobil 1 can go 12,000 kilometers or a year. But don't delay the first oil change—even with full synthetic, it's recommended to change it within 5,000 kilometers. A new car's engine is breaking in, and changing the oil early is like lubricating the new gears of a treadmill. Don't believe the nonsense about 'special formula oil for new cars'—change it when it's due.
