The BMW 325 is equipped with a 4-cylinder engine, model B48B20B, with a maximum power output of 135 kW and a maximum torque of 300 Nm. The engine of the BMW 325 is assembled in China using German technology and is produced at the Shenyang Tiexi factory. For daily maintenance of the BMW 325 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment 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 standard meets or exceeds the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any lubricating oil will degrade over time. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may rupture or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Regularly 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. These mix with metal particles from component wear, forming sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.
