How often should the engine be maintained?

[LaJoel]

Engine maintenance is recommended every 5,000 kilometers or every six months. The maintenance interval also depends on the type of oil used. For ordinary mineral oil, it's every 5,000 kilometers, while for better semi-synthetic oil, it can be extended to around 7,000 kilometers. Key points of engine maintenance: 1. Use the appropriate grade of engine oil and change the oil and filter regularly; 2. Maintain the air filter frequently and replace it periodically; 3. Clean the fuel system regularly and replace the fuel filter; 4. Maintain the radiator mesh regularly; 5. Replace spark plugs periodically. Essential maintenance tasks include changing the engine oil and oil filter. Regular car maintenance should include frequent car washing, and key areas to check regularly are tire surface and pressure, oil level, coolant level, and brake fluid level.
