How to Maintain a Car Engine?

Here are specific methods for maintaining a car engine: 1. Maintain good crankcase ventilation. Most gasoline engines today are equipped with a PCV valve, but airborne contaminants can accumulate around the valve, potentially clogging it. Regularly clean the contaminants around the PCV valve. 2. Change the oil and oil filter regularly. The quality of any grade of lubricating oil will degrade over time during use. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. 3. Clean the crankcase regularly. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Therefore, the crankcase should be cleaned regularly to keep the engine interior clean. 4. Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB-CD grade diesel engine oil according to mechanical load, ensuring the selected standard meets or exceeds the manufacturer's specified requirements.

I have plenty of experience in engine maintenance. Regular oil changes are absolutely fundamental – I always supervise the mechanic during service to ensure fresh oil and a new filter are installed. Before daily startup, I check the coolant level to prevent engine overheating and cylinder scoring. On highways, I pay special attention to the temperature gauge and pull into rest areas if anything seems abnormal. Every six months, I remove and clean the air filter myself. For engines with severe carbon buildup, adding some fuel system cleaner helps. Just last week, I serviced my five-year-old car, and the engine still sounds crisp – the key is never delaying maintenance intervals and sticking to scheduled mileage-based servicing.

Engine maintenance involves four key aspects: Lubrication management requires selecting a full-synthetic oil with the appropriate viscosity, replacing it every 8,000 kilometers or six months. Intake system maintenance involves checking the air filter monthly, with shorter replacement intervals in dusty areas. The cooling system must maintain the antifreeze at the correct ratio, with a complete replacement every two years. The fuel system requires regular addition of legitimate fuel additives. Additionally, pay special attention to worn engine mounts causing abnormal vibrations, and the throttle body should be removed and cleaned every 30,000 kilometers. Lastly, do not forget to replace the oil filter whenever changing the engine oil.

Listen up, sisters! Here's my little maintenance secret: don't skimp on oil changes by choosing semi-synthetic oil. Good full synthetic oil protects your engine longer. Last time, my bestie's car was shaking badly, and we found out it was due to carbon buildup on the spark plugs. Now I always use 95-octane fuel with fuel additives. When driving, avoid stomping on the accelerator—being gentle is better for the engine. Remember to turn off the AC before parking to reduce startup strain. The dealership recently told me my engine internals look brand new, all because I stick to regular maintenance. Oh, and if your coolant turns cloudy, change it immediately—this is super important!
