How many liters of engine oil should be added to the Mercedes-Benz C260?

254915 is the engine model used in the Mercedes-Benz C260, with a maximum horsepower of 204 hp, a maximum power of 150 KW, a maximum power speed of 6100 rpm, and a peak torque of 300 N.m. The engine of the Mercedes-Benz C260 is imported and assembled domestically, with all parts being imported and assembled in the country. For the daily maintenance of the Mercedes-Benz C260 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. 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 will deteriorate, leading to various engine problems. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and the oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing the filter and carrying contaminants back to the lubrication areas, 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, mixing with metal powder from component wear to form sludge. When the amount is small, it remains suspended in the oil; when large, it precipitates out, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
The oil refill capacity for the Mercedes-Benz C260 typically ranges between 5.5 to 6 liters, depending on the model year. As an experienced veteran driver, I strongly advise against haphazard oil top-ups, as excessive oil can increase internal engine pressure, potentially leading to piston burning, while insufficient oil may cause inadequate lubrication and accelerated cylinder wear. The maintenance manual is the gold standard—always consult it before each oil change to confirm the exact amount, noting that newer models and AMG versions may require slightly more. Using the appropriate 0W-20 or 5W-30 synthetic oil enhances durability. Don’t forget to check the oil level regularly, ideally every 5,000 kilometers, to maintain optimal vehicle performance and fuel efficiency. Consistent adherence to these practices can significantly extend your car’s lifespan.
