For a car at 45,000 kilometers, the routine maintenance includes changing the engine oil and oil filter, replacing the air filter, cabin air filter, and fuel filter—essentially replacing all three filters. Additionally, a comprehensive inspection and cleaning of the entire vehicle should be performed. The most critical aspects of car maintenance are changing the engine oil and oil filter, washing the car, and regularly checking the tire tread and pressure, oil level, coolant level, and brake fluid level. Below are five key points for engine maintenance: Maintenance points: Use the appropriate grade of engine oil and change it regularly (every 5,000 kilometers) along with the filter. Maintain the air cleaner frequently and replace it periodically (every 20,000 kilometers). Clean the fuel system regularly and replace the fuel filter (every 30,000 kilometers). Service the radiator cooling mesh periodically (every 30,000 kilometers). Replace the spark plugs (every 40,000 kilometers or based on driving conditions).
