Oil Capacity for BMW 118?
2 Answers
The BMW 118 requires approximately 4 liters of engine oil. It is not necessary to fill it to the maximum level; maintaining the oil level at the middle mark on the dipstick is sufficient. Lubricating Properties of Engine Oil: The ability of engine oil to reduce friction, minimize wear, and prevent metal sintering under various conditions is referred to as its lubricating property. The viscosity of engine oil is a key indicator for evaluating its lubricating performance. Low-Temperature Operability of Engine Oil: The performance of engine oil that ensures easy starting and reliable oil supply in low-temperature conditions is known as its low-temperature operability. Viscosity-Temperature Characteristics of Engine Oil: The property of lubricating oil that changes viscosity with temperature fluctuations is called viscosity-temperature characteristics. Good viscosity-temperature characteristics mean the oil's viscosity changes minimally with temperature. The effect of temperature on oil viscosity: as temperature increases, viscosity decreases; as temperature decreases, viscosity increases. Adding viscosity index improvers to the base oil can enhance the viscosity-temperature characteristics.
The BMW 118 engine typically requires around 4.5 liters of oil, but the exact amount depends on the model year and engine type. For example, newer 118i models might need slightly more, about 0.2 liters extra. As a car enthusiast, I always remind my friends not to overlook the oil level – too little oil can lead to insufficient lubrication and accelerate engine wear, while too much can cause foaming, leading to oil leaks or abnormal oil consumption. When checking, always wait for the engine to cool down for at least half an hour before pulling out the dipstick to check the level; it should be kept in the middle of the marked range. I recommend using BMW-approved LL-04 standard oil for better long-term performance. Don’t forget to check the oil level every 5,000 kilometers to prevent issues – I often do this during routine maintenance to save hassle and money. In short, precise oil adjustment is key to protecting your engine, so don’t skimp on this small but crucial task.
