Oil filter, air filter, cabin air filter, engine oil, coolant, brake fluid, etc. Engine oil replacement: Engine oil is the lubricating oil for engine operation. It lubricates, cleans, cools, seals, and reduces friction in the engine. It plays a significant role in reducing wear on engine components and extending their service life. You can determine whether the oil needs to be replaced by observing changes in its viscosity, checking if its odor has faded, and examining any color changes. Oil filter replacement: The oil filter is the component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, moisture, and additives. During engine operation, metal particles generated by friction between components, airborne impurities, and oil oxidation products are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circuit, it will adversely affect the engine's performance and lifespan. Air filter replacement: During operation, the engine inhales a large amount of air. If the air is not filtered, the dust in it can accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe cylinder scoring. The air filter's function is to remove dust and particles from the air, ensuring that sufficient, clean air enters the cylinder.
I've been driving BMWs for many years, so I'm quite familiar with routine maintenance. It's necessary to get it done every 5,000 to 10,000 kilometers, mainly for oil and oil filter changes, otherwise the engine wears out too quickly and might even need a major overhaul. Next, check the brake pads and discs to ensure they're thick enough—safety first. Tire inspection is also essential, carefully checking both pressure and wear to prevent skidding in the rain. The entire lighting system should be tested, including headlights, taillights, and turn signals, to avoid accidents when driving at night. It's also a good idea to replace the cabin air filter to keep the air inside the car clean and healthy. Regularly check and top up the coolant and battery to prevent breakdowns on the road. I've learned my lesson—last time I delayed maintenance, and a faulty spark plug cost me over 2,000 yuan to fix. Timely maintenance saves money and gives peace of mind. I recommend getting it done at a 4S shop or a trusted repair shop.
