120 km/h at 1500 RPM is not normal, the normal RPM range should be between 2000 and 3000. The following are the maintenance precautions for car engines: Use high-quality engine oil: Engine oil, which serves as the lubricant for the engine, provides lubrication, cleaning, cooling, sealing, and wear reduction. Only by using qualified lubricating oil can you reduce the wear of engine components and extend their service life. Therefore, it is important to always use high-quality lubricating oil. Regularly clean the car's fuel system: To maintain the engine, it is essential to properly care for the fuel system. Regularly cleaning the car's fuel system can control the formation of carbon deposits, keeping the engine in optimal condition. Periodically clean the radiator scale: Rust and scale buildup in the engine radiator are common issues. Rust and scale can restrict the flow of coolant in the cooling system, reducing heat dissipation and causing the engine to overheat, which may even lead to engine damage. Therefore, in daily maintenance, it is necessary to choose a coolant with the appropriate ratio based on specific conditions.
