How Much Engine Oil Remaining Requires Maintenance
1 Answers
Under normal circumstances, when the engine oil life drops below approximately 10%, the vehicle's combination meter will issue a reminder, indicating the need for maintenance. Below are the key considerations for automotive maintenance: 1. Use lubricating oil of appropriate quality grade: The selection standard should not be lower than the manufacturer's specified requirements. 2. Regularly change the engine oil and filter: The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, potentially causing various engine issues. To prevent malfunctions, oil should be changed regularly based on usage conditions, maintaining an appropriate oil level. 3. Maintain good crankcase ventilation: Regular maintenance of the PCV system is necessary, including cleaning contaminants around the PCV valve. 4. Periodically clean the crankcase: 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. Small amounts remain suspended in the oil, while larger quantities can precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Additionally, oil oxidation at high temperatures forms varnish and carbon deposits that adhere to pistons, increasing fuel consumption, reducing power, and in severe cases, causing piston rings to seize and cylinder scoring. Therefore, regular crankcase cleaning is essential to maintain engine cleanliness. 5. Periodically clean the fuel system: As fuel travels through the fuel lines to the combustion chamber, it inevitably forms gums and carbon deposits that accumulate in fuel passages, carburetors, injectors, and combustion chambers, disrupting fuel flow, altering the air-fuel ratio, impairing fuel atomization, and leading to engine issues such as rough idling, knocking, unstable acceleration, and poor performance. Regular fuel system cleaning ensures optimal engine operation. 6. Regular radiator maintenance: Rust and scale buildup in the engine radiator are common issues. These deposits restrict coolant flow, reducing cooling efficiency and potentially causing engine overheating or damage. Oxidized coolant can also form acidic substances that corrode metal radiator components, leading to leaks. Regular radiator cleaning to remove rust and scale not only ensures proper engine function but also extends the lifespan of both the radiator and the engine.
