How many liters of engine oil should be added to the BMW 118i three-cylinder engine?

The BMW 118i three-cylinder engine requires 4 liters of engine oil. Engine oil plays a crucial role in lubrication, cleaning, sealing, buffering, rust prevention, and heat dissipation within the engine. Without engine oil, the engine cannot operate. Over time, the performance of engine oil degrades, necessitating regular replacement. During each oil change, the oil filter should also be replaced. The BMW 118i is a performance sports car produced by BMW, equipped with a 1.6-liter turbocharged engine featuring BMW TwinPower Turbo technology. This includes a twin-scroll single turbocharger, high-precision direct injection system, VALVETRONIC electronic valve control, and Double VANOS dual variable camshaft timing system. It delivers a maximum power of 125 kW and a maximum torque of 250 Nm.
I've previously owned a BMW 118i three-cylinder model. The oil capacity is approximately 4.25 liters, and I always strictly adhere to the standard range during oil changes. Fully synthetic oil like 5W-30 is the most suitable choice—don't forget to replace the oil filter, or old contaminants may clog the system. For routine maintenance, I make it a habit to check the dipstick to ensure the oil level stays between min and max marks. Overfilling increases engine pressure, while underfilling accelerates component wear. Before long trips, I always verify oil quality. Though three-cylinder engines are fuel-efficient, they tend to run hot—proper oil levels prevent overheating issues. Never neglect regular maintenance intervals; following the dealership's recommended 10,000-km oil change schedule keeps the car running smoothly and safely.
From a mechanic's perspective, the BMW 118i three-cylinder engine typically requires 4.3 liters of oil. I've personally changed oil on quite a few of these. When it comes to tools, using a measuring cup for accuracy and selecting the right oil specification is crucial—5W-40 is common, but always check the manual for recommendations. The process is straightforward: first drain the old oil from the oil pan, clean the filter housing before installing the new filter, and pour in the new oil slowly without rushing. I always remind car owners to run the engine for a few minutes after an oil change and then recheck the oil level, keeping it within the standard range for optimal performance. Neglecting oil issues can lead to increased engine noise or oil burning, potentially resulting in repair costs upwards of a thousand dollars. Regular maintenance is the most cost-effective and worry-free approach.
