It is not mandatory to service a car every three months. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. Maintenance items include: 1. Changing engine oil, oil filter, air filter, and fuel filter; 2. Inspecting the body and tires; 3. Checking the braking system; 4. Examining the chassis for damage; 5. Checking the fluid levels. The benefits of car maintenance: 1. Ensuring the vehicle's optimal performance; 2. Enhancing driving safety; 3. Reducing engine noise; 4. Extending the vehicle's lifespan.

As a veteran driver with over 20 years of experience, I can tell you that maintenance intervals aren't strictly every three months. Every vehicle's owner manual clearly specifies the schedule - my Japanese car requires service every six months or 5,000 km. It largely depends on the oil type: mineral oil might justify three-month intervals, but most modern cars using full synthetic can easily go 10,000 km. The key factor is your driving conditions - my highway-heavy usage allows longer intervals, whereas frequent off-road or construction site driving would require more frequent maintenance. Last time at the dealership they pushed for three-month service, but checking the manual revealed it was just upsell.

When I first bought my new car, I was also puzzled about the maintenance intervals. Later, I found that manufacturers' recommendations vary greatly. The owner's manual for American cars suggests every six months or 8,000 kilometers, while German cars directly mark one year or 15,000 kilometers. Nowadays, the lifespan of mainstream full synthetic oils generally exceeds 10,000 kilometers, unless you're off-roading in mud every day or frequently making short trips with constant starts and stops. During my last maintenance, I asked the mechanic to check the oil condition, and after eight months of driving, it hadn't oxidized or turned black. In fact, regularly checking tire pressure is much more important than rigidly adhering to a three-month cycle—it saves unnecessary expenses and doesn't harm the car.

The technology in new cars nowadays is far from what it was a decade ago, and maintenance intervals are much more flexible. My turbocharged car followed the manual's recommendation of servicing every 10,000 kilometers for the first two years, and the engine still runs smoothly. The key factors to consider are: don't skimp on oil quality—it's advisable to choose SP-grade full synthetic oil; whether your actual driving habits are aggressive; and how frequently the vehicle is used. My neighbor's city commuter car only clocks 3,000 kilometers in six months, so it waits a full year for maintenance as per the manufacturer's standard. Of course, exceptions exist for extremely cold winter regions in the north, where low temperatures do necessitate shorter intervals to check the antifreeze.
