Mainly replace the engine oil and oil filter. Below are the relevant details about car maintenance: 1. Engine oil and oil filter replacement: The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter removes impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car requires maintenance every 5,000 kilometers. 2. Air filter replacement: The air filter cleans the air before it enters the cylinders by removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced every 20,000 to 25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are part of the inspection items during routine maintenance and should be serviced or replaced based on their condition.
My car just passed 100,000 kilometers recently, and I had a long chat with the mechanic. Besides the routine oil and three-filter changes that are must-dos, there are several key areas to focus on: the transmission fluid needs a complete replacement, as prolonged neglect can lead to gear shift jerks; check the brake disc thickness and brake pads – last time mine were worn down to only 3mm; the coolant should also be replaced, or else it's prone to overheating in summer. Pay special attention to the belts, particularly the timing belt, which the mechanic checked for me using an endoscope while inspecting the engine condition. The aging of chassis rubber bushings is easily overlooked – the lower control arm bushings on my car were cracked. It's advisable to conduct a full electrical system check, as wiring in older cars tends to develop issues. Hitting 100,000 kilometers is like a physical check-up for your car; don't skimp on the necessary inspections.
