It is recommended to perform maintenance and change the engine oil every 50,000 kilometers. General maintenance is divided into internal and external upkeep. External upkeep, such as paint care, can be done by yourself. This includes car washing and waxing every 2-3 months. Otherwise, the car's paint surface may develop small scratches, oxidation layers, dirt, etc. So, regular maintenance is essential—after all, the paint represents your car's appearance. Personally, I use E8 wax, which has worked well for me over several months. You can check it out on Taobao—it's best to get the complete set. For internal maintenance, the most critical tasks are changing the engine oil and oil filter. The key areas to frequently inspect include tire surfaces and pressure, oil level, coolant level, and brake fluid level. These tasks cannot be done by yourself and require a professional service. Here are five essential points for engine maintenance: 1. Use the appropriate grade of engine oil and change it regularly (every 5,000 kilometers); 2. Frequently maintain the air filter and replace it periodically (every 20,000 kilometers); 3. Clean the fuel system regularly and replace the fuel filter (every 30,000 kilometers); 4. Maintain the radiator and cooling system (every 30,000 kilometers); 5. Replace spark plugs (every 40,000 kilometers or as needed based on driving conditions).
